Microstructure Evolution of Solid State Reacted HAp/β-TCP Composite Powders by Post-Treatment Processing

ABSTRACT

Biphasic Calcium Phosphate (BCP) consisted of hydroxyapatite (HAp) and $beta$-tricalcium phosphate (P-TCP) has been prepared by solid state reaction. The size reduction of the resultant BCP agglomerate was carried out by reaction with hot water under atmospheric condition uld also under high pressure using an autoclave. The influence of processing conditions on the change of crystalline phase and composition, relative amount of constituent, specific surface area, and microstructure was investigated by means of XRD, FT-IR, BET method using a nitrogen adsorption and SEM.

Key words: Solid state reaction, BCP, HAp, $\beta$-TCP, Size reduction
