On the development of an apatitic calcium phosphate
Abstract. Development of an apatitic calcium phosphate bone cement is reported. 100 µ Particles of tetra-calcium phosphate (TTCP) and dicalcium phosphate dihydrate (DCPD) were mixed in equimolar ratio to form the cement powder. The wetting medium used was distilled water with Na 2HPO 4 as accelerator to manipulate the setting time.
