Description

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.

Application

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