Synthesis and Characterization of Pure and Co-Substituted ß-TCP Powders

Abstract

According to the similarity of calcium phosphate structure with that of human bone, they are the most used in different medical applications. Among these bioceramics, β-TCP has very important and different properties, which can be modified by several approaches, including changing chemical composition by substitution. This chapter objects to work on cationic substitution using magnesium (Mg) and copper (Cu); this study aims to synthesize pure monophasic β-TCP powders and other β-TCP powders substituted by bivalent ions of Mg and copper, using the aqueous precipitation method with controlled amounts of Mg2+ and/or Cu2+ ions. The results obtained describe the variation of unit cell parameters and the grain size with the nature of substituted ions and the substitution rate.
