摘　　要：通过TEM、XRD、TG和DAT分析,研究了用溶胶-凝胶法制备羟基磷灰石过程中,反应气氛、钙磷摩尔比和热处理等条件对反应产物的影响。结果表明,反应气氛和钙磷摩尔比对反应产物结构和性能有重要影响,反应气氛决定着反应产物颗粒的形貌和大小,钙磷摩尔比决定了在热处理过程中可以生成何种晶形。Influences of reaction atmosphere,Ca/P molar ratio and heat treatment on the hydroxyapatite prepared by sol-gel method were studied by using TEM, XRD, TG and DTA analysis. Results show that reaction atmosphere and Ca/P molar ratio have significant effects on the structures and properties of the product. Atmosphere determines the particle size and morphological properties of the product and different Ca/P ratio causes different crystal morphology after heat treatment.
