Preparation of Porous Hydroxyapatite/TCP Composite Block Using a Hydrothermal Hot Pressing Method
The hydrothermal hot pressing (HHP) technique is a method by which hard solid bodies of powders can be produced in a short time and at a relatively low temperature under saturated vapor pressure. In this study, the hydrothermal hot pressing (HHP) technique is used for preparing porous hydroxyapatite/TCP block having a high mechanical strength. The SEM result of the sample shows that all the pores are interconnected from 200µm to 300µm in sizes. The observed X-ray powder diffraction pattern of the sample after sintering at 1200oC is composed of hydroxyapatite and tricalciumphosphste.
