Abstract

A new synthesis technique for making hydroxyapatite (HAp) ceramics has been developed using hydrothermal hotpressing (HHP) method at relatively low temperature below 150°C. Powder mixture of dibasic calcium phosphate dihydrate and calcium hydroxide with the Ca/P ratio of 1. 67 was treated at 150°C and 40MPa. The resulted solidified body could be identified as HAp by X-ray diffraction (XRD) analysis. Moreover we tried to prepare Chitosan-HAp composite for practical utilization of low-temperature-process. Chitosan-HAp composite was improved the tensile strength twice times and over up as compared with plain HAp ceramics.
