摘 要: 通过对不同温度和保温时间制备的多孔HA种植体试样进行测试分析,研究了烧结条件对材料气孔率、 体积密度、 吸水率、 晶粒尺寸和弯曲强度的影响。 结果表明: 随着烧结温度的升高和保温时间的延长, 气孔率和吸水率减小, 体积密度和弯曲强度升高;晶粒长大填充气孔, 使多孔材料孔隙率下降而强度增加。

Abstract:Through the testing and analysis of porous HA implant prepared under different sintering conditions, the effects of sintering temperature and time on the porosity, bulk density, water absorption, grain size and bending strength were studied. The results show that the porosity and water absorption decrease and the bulk density and bending strength increase, along with the sintering temperature raising and the time prolonging. The grains growth filling in the pores causes the porosity to decrease and the strength of the porous material to increase.
