溶胶-凝胶法制备羟基磷灰石粉体化学机理分析

Chemistry Mechanism Discussion of Preparing HAP with Sol-gel Method

利用硝酸钙醇溶液和五氧化二磷醇溶液,通过溶胶-凝胶法,制备了羟基磷灰石(HAP)粉体.对前驱体和不同热处理温度的HAP粉体试样进行了FTIR与XRD测试分析,讨论分析了在溶胶-凝胶法制备HAP过程中HAP生成化学反应的机理.

HAP powder was prepared from Ca（ NO3 ）2 · 4H20 and P2O5 with Sol-gel method. The chemical mechanism of Sol-gel synthesizing Hydroxyapatite was investigated through analyzing the ethanol solution of P2O5 and Ca（ NO3 ）2·4H2O, the Hydroxyapatite precursor powder and the Hydroxyapatite precursor powders calcined at different temperature with analytical methods of FTIR and XRD.
