Application

Calcium phosphate monobasic monohydrate may be used in the preparation of calcium polyphosphate (CPP) powders.

General description

Calcium phosphate monobasic monohydrate is mainly used in the manufacture of fertilizers and as an acidulant in food industry. Aqueous solution of calcium phosphate monobasic monohydrate (MCPM) mixed with α-tertiary calcium phosphate forms dicalcium phosphate dihydrate cement. It is also used in composing brushite cement.

Calcium phosphate cements (CPCs) have been widely used as bone graft substitutes. However, the undesirable osteoinductivity and slow degradability of CPCs greatly hamper their clinical application. The aim of this study was to synthesize a type of injectable, bioactive cement.
