Description

General description

Calcium phosphate (tri calcium phosphate) is a colorless amorphous solid. Its pure form can be obtained by melting CaO with phosphorus (V) oxide at 1100°C. It is used as polish in toothpastes and also in making enamels and opaque glasses.

Calcium phosphate occurs naturally as the minerals: oxydapatit, voelicherite and whitlockite. It is mainly used for developing osteoconductive biomaterials for use as bone substitutes.

Application

Composite of calcium phosphate and a bioactive glass may be employed for the manufacture of customized implants, via 3D-printing process. Dense and homogeneous calcium phosphate coatings may be used for coating the metal implants.
