Abstract:

To avoid microcrack formation caused by the addition of heterogeneous sintering aids, nano hydroxyapatite powder was prepared by precipitation method and doped into commercial hydroxyapatite powders as homogeneous sintering aid. Gelcasting method was used to prepare these hydroxyapatite green bodies. Densification of the blended powder was performed by pressureless sintering in air atmosphere at the range 1100°C to 1400°C for 2h, with a step size of 50°C. The results showed that the nano particle can greatly improve the densification process of the green bodies, and at 1300°C, which is the highest sintering temperature for hydroxyapatite without decomposition in the air atmosphere, the relative sintering densities of the doped green bodies and the ones without doping were 93.99% and 83.13% respectively.
