Calcium phosphate (CAS 7758-87-4), most commonly referred to as tricalcium phosphate or tribasic calcium phosphate, is an inorganic calcium salt of phosphoric acid. It appears as a white, odorless, amorphous or crystalline powder. While practically insoluble in water, it readily dissolves in dilute acids like hydrochloric and nitric acid. Calcium phosphate is a vital mineral component of bones and teeth and is widely utilized across various industries for its chemical and physical properties.
Product Properties:
Property Value CAS Number 7758-87-4 Molecular Formula Ca₃(PO₄)₂ Molecular Weight 310.18 g/mol Appearance White amorphous or crystalline powder Solubility Practically insoluble in water and ethanol; soluble in dilute HCl and HNO₃ Density Approximately 3.14 g/cm³ Primary Form Tricalcium phosphate (Tribasic calcium phosphate) Synonyms Tricalcium phosphate, Tribasic calcium phosphate, Calcium orthophosphate, Bone phosphate of lime (BPL) Product Usage:
Calcium phosphate (tricalcium phosphate) has diverse applications. In the food industry, it serves as an anti-caking agent (e.g., in spices, powdered sugar), a nutritional supplement (providing calcium and phosphorus), an acidity regulator, and an emulsifier in products like powdered drinks and infant formula. Pharmaceutical applications include its use as an excipient (diluent, binder) in tablets and capsules, and as a calcium supplement. It is also a key biomaterial in dental applications and bone grafts due to its biocompatibility. Agriculturally, it’s used in animal feed and as a fertilizer. Other industrial uses include the production of phosphoric acid, ceramics, and polishing agents.
