Abstract
Calcium phosphate is a biomaterial which exhibits excellent biocompatibility, bioactivity and biodegradability for bone replacement and other medical applications. In the present work, multiphasic calcium phosphate compounds consisting of hydroxyapatite (HAp) and tri-calcium phosphates (TCP) were prepared by a solid state reaction method. Effects of calcium carbonate (CaCO3: ±3-5 wt%) on the properties of the studied powders were investigated where calcium carbonate powder was synthesized from a natural product (cockle shell). The phase formation and morphology of the powders were characterization by many techniques such as XRD, SEM and dynamic light scattering techniques. The results showed that amount of calcium carbonate additive affected on the properties of the studied samples.
