湿法合成纳米羟基磷灰石粉末的研究

摘要

Synthesis of hydroxyapatite(HAP)ranometer powder by wet process from Ca(NO3)2·4H20 and (NH4)2HPO4 in two different solvent system(water and water-alcohol) was studied. The results show that solvent system, reacting temperature, washing agent and washing-leaching times can influence the perticle size of HAP powder. HAP ultrafine powder with 20～50 nm was obtained under a suitable condition.%对以硝酸钙和磷酸氢二铵为先驱体，在水及水－乙醇两种体系下采用湿法制备纳米羟基磷灰石粉体进行了研究。研究发现，溶剂体系、反应温度、凝胶清洗用剂及洗滤次数等对所得的粉体粒度有较大的影响。在适当的条件下制备出了粒度为20～50nm的羟基磷灰石超细粉体。
