Preparation of Porous Hydroxyapatite / Tricalcium Phosphate Composite Block Using a HHP Method

Article Preview

Abstract:

Porous hydroxyapatite/tricalcium phosphate composite block has been prepared using a hydrothermal hot pressing (HHP) technique to achieve having a high mechanical strength and controlled biodegradability. The SEM result of the sample shows that the pore sizes are ranged from 100µm to 300µm. The observed X-ray powder diffraction pattern of the sample after sintered 1200oC is composed of hydroxyapatite and tricalciumphosphste.
