Calcium Phosphate, Tribasic, occurs as a white powder that is stable in air. Tribasic Calcium Phosphate consists of a variable mixture of calcium phosphates having the approximate composition 10CaO • 3P2O5 • H2O. It contains NLT 34.0% and NMT 40.0% of calcium (Ca). It is insoluble in alcohol and almost insoluble in water, but it dissolves readily in dilute hydrochloric and nitric acids.



1) In the food industry, it can be used as anti-caking agent, nutritional supplement, flavoring agent, buffer, pH regulator, and also as a poultry feed additive and antacid.

2) Used as a mordant, and also used for the coloring of ceramics, glass, paint, etc.
