SYNTHESIS OF BIPHASIC CALCIUM PHOSPHATE MINERALS FROM SHELLS OF POKER-CHIP VENUS

Abstract

The scientific community is widely interested in synthetic biomaterials, calcium phosphate - based bioceramics, such as biphasic calcium phosphate (BCP), because of its potential applications. Biphasic calcium phosphate (BCP) is known as a bioceramic which is a mixture of hydroxyapatite and β -tricalcium phosphate in fixed ratios that can be used for a bone substitute. In this research, biphasic calcium phosphate was synthesized from the shell powder of poker-chip venus by using ethyl phosphate as a reducing agent by the aqueous precipitation technique. The sample powder was determined by X-ray diffraction and the morphology of the synthesised powder was determined by field emission scanning electron microscopy while Fourier-transform infrared spectroscopy was used to confirm the chemical bonds in the BCP powder.
