【摘要】 进一步探索了用溶胶-凝胶法制备羟基磷灰石粉末的工艺条件。实验表明:获得理想样品的最主要条件是硝酸钙和磷酸三甲酯的质量比约为2.86∶1,溶胶液的pH值应取7左右。烧结温度控制在550~650℃,恒温时间控制在1.5~3h,对于制备HA复合种植体特别重要。

【Abstract】 The technique conditions for the preparation of HA powder by SolGel process are investigated again.The experiment shows that the principal conditions to gain the perfect sample is the mass ratio of Ca(NO32·4H2O∶(CH3O)3·PO=2.86∶1;the pH value of Sol liquid should be taken 7;the sintering temperature should be controlled at 550~650 ℃ and the constant temperature maintained 1.5~3 h.These conditions are of great importance to the preparation of Hydroxyapatite conplex growth bed.
