Tricalcium phosphate (TCP) is a calcium salt of phosphoric acid with the chemical formula Ca3(PO4)2. It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite. It is a white amorphous powder and non-flammable. Tricalcium phosphate can be produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime.

In some toothpaste hydroxyapatite can be found in the form of nanocrystals.
- To reduce dental hypersensitivity, hydroxyapatite nanocrystals (nHA) have been utilised in toothpaste.
- They assist to repair and remineralize the enamel, which helps to avoid dental sensitivity.
- Tooth enamel can become demineralised as a result of a variety of factors, including acidic erosion and dental caries. If left untreated, this can result in dentin exposure and, as a result, tooth pulp exposure.

Nano-hydroxyapatite possesses a remineralising effect on teeth; prevent damage from carious attacks.

In the event of an acid attack by cariogenic bacteria, nano-hydroxyapatite particles can infiltrate pores on the tooth surface to form a protective layer.

Hydroxyapatite is a potential adsorbent for the defluoridation of drinking water.

When an autogenous bone transplant is neither practical or practicable, tricalcium phosphate can be utilised as a tissue substitute to heal bony abnormalities. It can be employed alone or in conjunction with a resorbable, biodegradable polymer like polyglycolic acid. It can also be used to make a bone transplant when mixed with autologous components.

Tricalcium phosphate is produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime.

Typically double decomposition reactions are employed, involving soluble phosphate and calcium salts, e.g. (NH4)2HPO4 + Ca(NO3)2 is performed under carefully controlled pH conditions. The precipitate will either be "amorphous tricalcium phosphate", ATCP, or calcium deficient hydroxyapatite, CDHA, Ca9(HPO4)(PO4)5(OH), (note CDHA is sometimes termed apatitic calcium triphosphate).

Crystalline tricalcium phosphate can be obtained by calcining the precipitate. β-Ca3(PO4)2 is generally formed, higher temperatures are required to produce α-Ca3(PO4)2.

An alternative to the wet procedure entails heating a mixture of calcium pyrophosphate and calcium carbonate.

Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral  form of  calcium apatite.Usually written Ca₁₀(PO₄)₆(OH)₂ to denote that the crystal unit cell comprises two entities.It crystallizes in the hexagonal crystal system . Pure hydroxyapatite powder is white and also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis.

Chemically, tricalcium phosphate is a calcium salt of phosphoric acid. Its primary function in fortification is to increase the calcium content of foods.

Due to its mineral source, tricalcium phosphate can be used in vegan foods and is also allowed in organic products in the U.S.
