摘　　要：为了方便快速地获得高纯度羟基磷灰石,本研究以(NH4)2HPO4和Ca(NO3).24H2O为原料,利用沉淀法制备纳米级羟基磷灰石粉末。对温度、pH值、分散剂添加比例、钙磷比、烧结温度等反应控制条件进行了研究,对钙磷比及烧结温度做了详细的讨论。结果表明:此法可以得到分散性、均匀性好,纯度高、颗粒小、晶形完整的纳米级羟基磷灰石。To facilitate quick access to high-purity hydroxyapatite,（NH4）2HPO4 and Ca（NO3）2o 4H2O were used as raw materials to prepare nanometer hydroxyapatite powders by precipitation method and the process of preparation was described in detail.The temperature of the reaction,pH value,proportion of added dispersing agent,and especially calcium and phosphorus ratio,and sintering temperature were studied.The results showed that well-dispersed nano-hydroxyapatite powders with good uniformity,high purity,small particle,and high crystallinity can be obtained by this method.
