Abstract
A new processing technique for preparing hyroxyapatite (HAp) ceramics has been developed using the hydrothermal hot-pressing (HHP) method, p owder mixed dibasic calcium phosphate dihydrate and calcium hydroxide mixed with a Ca/P ratio of 1.67 was treated at 150 degrees C and 40 MP a. The HHP method with the selection of the powder enabled the HAp to be solidified at the low temperature, The resulting HAp ceramics had a tensile strength of approximately 10 MPa, Furthermore, the HAp cerami cs possessed a lamellar microstructure and high porosity.
