Calcium phosphate tribasic CAS 12167-74-7 TCP

Tricalcium phosphate (TCP) is a compound with calcium phosphate as the main component, with the chemical formula of Ca₃(PO₄)₂, which is widely used in the fields of food, medicine and materials. ‌

Basic properties
Tricalcium phosphate is a white crystal or amorphous powder, which is insoluble in water and soluble in dilute acid. Its melting point is 1670℃ and it is stable in air. As a food additive, it mainly plays the role of anti-caking, buffering pH value, and retaining moisture. It is commonly used in the processing of flour, milk powder, candy, etc. ‌

Medical application
As a bioceramic material, tricalcium phosphate is highly matched with the inorganic components of human bone tissue (accounting for 65%). After implantation, it can form a chemical bond with the host bone through the formation of a hydroxyapatite layer on the surface to achieve a bone repair effect. It is mainly used for the repair of non-load-bearing bone defects (such as alveolar ridge augmentation, ear ossicle replacement, etc.), and can be used as a drug sustained-release carrier
