Abstract
The strength (MPa), hardness (Hv), shrinkage (%) and biological properties of the HAp were measured by using an organic plasticizer which facilitates the molding and heat treatment. Mechanical properties such as compressive strength, bending strength and hardness were increased with increasing amount of plasticizer, but mechanical properties were decreased when plasticizer was added more than 7 %. This is because addition of the plasticizer above the allowable value causes cracking during molding, and such cracks promote the generation of microcracks and pores at the time of sintering, resulting in a decrease in mechanical properties. As a result of the antimicrobial activity test, no bacteria were detected regardless of the addition amount of plasticizer.
