In the recent years, metal sulfide nanostructured materials have become established in different research fields thanks to their excellent properties. Among the potential applications, metal sulfides may have a high standing role for gas sensing, in which, despite the wide assortment of sensing materials, still metal-oxides maintain a leading role because of their high sensitivity, low cost, small dimensions and simple integration. Experimentation carried out in this work with CdS and SnS2 thick film sensors has showed an unexpected improvements of the chemoresistive properties with respect to their oxides counterparts, in particular toward selectivity to specific compounds, stability and the possibility to operate at room temperature. This opens towards the study of a novel class of sensing materials, which may solve the constant drift of the signal suffered by metal-oxides and ascribed to the in/out diffusion of oxygen vacancies, which alters the doping level.

Metal oxides are of great technological importance in environmental remediation and electronics because of their capability to generate charge carriers when stimulated with required amount of energy. The promising arrangement of electronic structure, light absorption properties, and charge transport characteristics of most of the metal oxides has made possible its application as photocatalyst. In this article definition of metal oxides as photocatalyst, structural characteristics, requirements of the photocatalyst, classification of photocatalysts and the mechanism of the photocatalytic process are discussed.

Silicon compound:  This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of silicon. For each compound, a formal oxidation number for silicon is given, but the usefulness of this number is limited for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. The term hydride is used in a generic sense to indicate compounds of the type MxHyand not necessarily to indicate that any compounds listed behave chemically as hydrides. In compounds of silicon (where known), the most common oxidation numbers of silicon are: 4, and -4.

Metal oxides are crystalline solids that contain a metal cation and an oxide    anion.A general property of metal oxide is that they tend to react with water to form basic solutions of metal hydroxide . For example copperoxide and sodium hydroxide.  Numerous theoretical and experimental aspects of metal oxide nanostructures used in the energy harvesting have been demonstrated.
Metal Carbonate:  Metal carbonates such as calcium carbonate break down when heated strongly. This is called thermal decomposition. ulfuric acid + zinc carbonate → zinc sulfate + water + carbon dioxide. The salt that is produced depends upon which acid and which metal react. The following table provides a summary of the name of the salt produced by different reactions between acids and metal carbonates.

Metal carbonate:

Carbonates are compounds formed between a metal and the carbonate ion, (CO3)2-. When a carbonate decomposes, a metal oxide and carbon dioxide gas are produced. The general pattern of a decomposition of a carbonate reaction is: MCO3 --> MO + CO2 (M is used to represent the metal. CO3 is carbonate.)

Mixed metal oxide (MMO) pigments, also known as complex inorganic color pigments (CICPs), have been around since the early 1800s. Their use in the ceramic and pottery industries is well known due to their overall inertness, which contributes to outstanding heat, chemical and UV resistance. The use of MMOs in industrial coatings is less common and more for special purposes. This paper will discuss the benefits of formulating coatings with MMOs as a replacement for, or in conjunction with, the more common organic types.                                                Metal sulphide: Metal sulfides (designated as MSs, M = Fe, Co, Ni, Cu, Mo, Ti, W, Sn, Sb, etc.) have recently attracted increasing research interest worldwide. Benefiting from their high electrochemical activities, these MSs will play significant roles in low-cost and environmentally friendly energy storage/conversion systems. In this review, we summarize the up-to-date progress on the rational design and efficient synthesis of MSs with controlled morphologies, sizes, compositions, and micro/nano-structures, along with their applications as electrode materials for lithium/sodium/magnesium-ion batteries and supercapacitors, and electrocatalysts for the oxygen reduction reaction and the hydrogen evolution reaction. The associated challenges, problem-solving strategies, and future trends to broaden the horizons of MSs for energy-related applications will also be presented.
Sillicon:Silicon is a chemical element with symbol Si and atomic number 14. A hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor. It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, and lead below. It is rather unreactive, though less so than germanium, and has a very large chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by Jöns Jakob Berzelius. Its melting and boiling points of 1414 °C and 3265 °C respectively are the second-highest among all the metalloids and nonmetals, being only surpassed by boron (carbon sublimes rather than melts at atmospheric pressure, albeit at a higher temperature than boron).

Mixed metal oxide pigments are compounds comprised of a group of two or more metals and oxygen. The most common crystal structures are rutile (MeO2) hematite (Me2O3) or spinel (Me3O4). Metals commonly present include: cobalt, iron, trivalent chrome, tin, antimony, titanium, manganese and aluminum. Different metal combinations produce a wide spectrum of hues ranging from black to brown to green, blue, yellow and red. All MMOs are produced by a calcination process consisting of an intimate mixture of appropriate metal precursor materials being fired at temperatures of 800 to 1300 °C. It is this calcining process that creates the extremely stable metal oxide bonds. The chemical stability of these bonds affords the outstanding durability of this class of color pigments.

UV Durability

The chemical inertness of inorganic MMOs renders their excellent resistance to UV radiation and the elements encountered in the most extreme outdoor environments. Most organic pigments degrade when exposed for more than a few years in UV-intense tropical environments. High-performance organic pigments that do provide acceptable durability are typically very expensive, commanding two to four times the cost of a metal oxide pigment. MMOs are therefore the colorant material of choice for architectural coatings requiring extremely high durability such as the performance specified in AAMA 2605-05 (Architectural Aluminum Manufacturers Association). This specification calls for maintenance of color and gloss after 10 years exposure in south Florida.

Chemical Resistance

The exceptionally stable chemical bonds characteristic of MMO pigments make them insoluble in most chemicals including strong acid and alkali, and virtually all organic solvents. Because of this insolubility, coatings formulated with MMOs will not lose color due to pigment degradation even with the most extreme exposure to aggressive chemicals. Atmospheric pollution including acid rain, volcanic fallout and waste incineration does not chemically attack these pigments. Moreover, coatings requiring resistance to strong chemical exposure such as laboratory and chemical manufacturing facilities can use MMOs and be assured of color stability.

(METAL OXIDE)
its Due to its electronegativity, oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. Noble metal such as gold or platinum) are prized because they resist direct chemical combination with oxygen, and substances like gold(III) oxide must be generated by indirect routes.
The surface of most metals consists of oxides and hydroxides in the presence of air. A well-known example is aluminium foil, which is coated with a thin film of alunimium oxide that passivates the metal, slowing further corrosion. The aluminium oxide layer can be built to greater thickness by the process of electrolytic anodising. Though solid magnesium and aluminium react slowly with oxygen.Most metals, burn in air, generating very high temperatures. Finely grained powders of most metals can be dangerously explosive in air. Consequently, they are often used in solid fuel rocket

Metal Oxides thus typically contain an anion of oxygen in the oxidation state of - 2. Most of the Earth's crust consists of solid oxides, the result of elements being oxidized by the oxygen in air or in water. Hydrocarbon combustion affords the two principal carbon oxides: carbon monoxide and carbon dioxide. Even materials considered pure elements often develop an oxide coating. For example, aluminium foil develops a thin skin of Al₂O₃ (called a passivation layer) that protects the foil from further corrosion.[2] Individual elements can often form multiple oxides, each containing different amounts of the element and oxygen. In some cases these are distinguished by specifying the number of atoms as in carbon monoxide and carbon dioxide, and in other cases by specifying the element's oxidation number, as in iron(II) oxide and iron(III) oxide. Certain elements can form many different oxides, such as those of nitrogen.

Natural Mineral and It's Uses

The metallic compounds which are formed with metal and oxygen in the form of oxide ion (O ²⁻) are called as metal oxide.  Over 90% of the aluminium oxide, normally termed Smelter Grade Alumina (SGA), produced is consumed for the production of aluminium, usually by the Hall–Héroult process. The remainder, normally called speciality alumina is used in a wide variety of applications which reflect its inertness, temperature resistance and electrical resistance.  Is used in making  favored filler for plastics. Aluminium oxide is a common ingredient in sunscreen and is sometimes also present in cosmetics such as blush, lipstick, and nail polish.  Aluminium oxide flakes are used in paint for reflective decorative effects, such as in the automotive or cosmetic industries.  Aluminium oxide is widely used to remove water from gas streams.  Zinc oxide is added to many food products, including breakfast cereals, as a source of zinc, a necessary nutrient. (Zinc sulfate is also used for the same purpose.) Some prepackaged foods also include trace amounts of ZnO even if it is not intended as a nutrient.  Micronized and nano-scale zinc oxide and titanium dioxide provide strong protection against UVA and UVB ultraviolet radiation, and are used in suntan lotion, and also in UV-blocking sunglasses for use in space and for protection when welding, following research by scientists at Jet Propulsion Laboratory (JPL).

Metal Carbonate :  Silver carbonate is used as a reagent in organic synthesis such as the Koenigs-Knorr reaction. In the Fétizon oxidation, silver carbonate on celite serves as an oxidising agent to form lactones from diols. It is also employed to convert alkyl bromides into alcohols. As a base, it has been used in the Wittig reaction .  The main use of calcium carbonate is in the construction industry, either as a building material or limestone aggregate for road building or as an ingredient of cement or as the starting material for the preparation of builder's lime by burning in a kiln.  In the oil industry, calcium carbonate is added to drilling fluids as a formation-bridging and filtercake-sealing agent; it is also a weighting material which increases the density of drilling fluids to control the downhole pressure. Calcium carbonate is added to swimming pools, as a pH corrector for maintaining alkalinity and offsetting the acidic properties of the disinfectant agent.

Metal Sulphide :  Silver sulfide (Ag
₂S) is the sulfide of silver. It is useful as a photosensitizer in photography.  Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics. Sodium sulfide is primarily used in the kraft process in the pulp and paper industry.It is used in water treatment as an oxygen scavenger agent and also as a metals precipitant; in chemical photography for toning black and white photographs; in the textile industry as a bleaching agent, for desulfurising and as a dechlorinating agent; and in the leather trade for the sulfitisation of tanning extracts. It is used in chemical manufacturing as a sulfonation and sulfomethylation agent. It is used in the production of rubber chemicals, sulfur dyes and other chemical compounds. It is used in other applications including ore flotation, oil recovery, making dyes, and detergent. It is also used during leather processing, as an unhairing agent in the liming operation.

Silicon Compund : Silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula Si O 2. An estimated 95% of silicon dioxide produced is consumed in the construction industry, e.g. for the production of Portland cement. Silica, in the form of sand is used as the main ingredient in sand casting for the manufacture of metallic components in engineering and other applications. The high melting point of silica enables it to be used in such applications. Crystalline silica is used in hydraulic fracturing of formations which contain tight oil and shale gas. In cosmetics, its useful for its light-diffusing properties and natural absorbency. Hydrated silica is used in toothpaste as a hard abrasive to remove tooth plaque.  Several industrial and medical applications exist for silane and functionalized silanes. For instance, silanes are used as coupling agents to adhere fibers such as glass fibers and carbon fibers to certain polymer matrices, stabilizing the composite material. In other words, silane coats the glass fibers to create better adhesion to the polymer matrix. They can also be used to couple a bio-inert layer on a titanium implant. Other applications include water repellents, masonry protection, control of graffiti applying polycrystalline silicon layers on silicon wafers when manufacturing semiconductors, and sealants. The semiconductor industry used about 300 metric tons per year of silane in the late 1990s.  Silane is also used in supersonic combustion ramjets to initiate combustion in the compressed air stream.

More than two-thousand minerals have been identified and most of these contain inorganic compounds formed by various combinations of the eight elements (O, Si, Al, Fe, Ca, Na, K, and Mg) that make up 98.5% of the Earth’s crust. Industry depends on about 80 of the known minerals.

A mineral deposit is a concentration of naturally occurring solid, liquid, or gaseous material, in or on the Earth’s crust in such form and amount that its extraction and its conversion into useful materials or items are profitable now or may be so in the future. Mineral resources are non-renewable and include metals (e.g. iron, copper, and aluminum), and non-metals (e.g. salt, gypsum, clay, sand, phosphates).

Minerals are valuable natural resources being finite and non-renewable. They constitute the vital raw materials for many basic industries and are a major resource for development. Management of mineral resources has, therefore, to be closely integrated with the overall strategy of development; and exploitation of minerals is to be guided by long-term national goals and perspectives.
