The main applications of sodium are the preparation of dyes, detergents, the manufacture of sodium vapor lamps and the manufacture of tetraethyl lead. It is also used in the preparation of very valuable organic substances: obtaining sodium cyanide, obtaining sodium peroxide which is used as a bleach and oxidant in the textile and paper industry. Sodium is also used to increase the life of the exhaust valves of aviation engines based on their high thermal conductivity. Sodium fluoride, NaF, is used as an antiseptic, as poison for mice and rats, and for ceramics.
Sodium nitrate is used as fertilizer. Sodium thiosulfate, Na2S2O3 • 5H2O is used in the photograph as fixative. Sodium hydroxide, known commercially as caustic soda, is used in the manufacture of soap, rayon and paper, in petroleum refining and in the textile industries
