将羟基磷灰石（HAp）与透钙磷石（TCP）反应烧结，制备了不同配比的HAp/β-TCP陶瓷复合材料。用TG、DTA等方法对反应过程进行了分析，结果表明该反应涉及多步反应。发现β-TCP在约800°C下形成，透钙磷石的存在增强了HAp的初始阶段烧结。产物中β-TCP与HAp的比例可以通过改变初始混合物中透钙磷石的浓度来控制。
Microstructure-controlled ceramic composites composed of various ratios of hydroxyapatite (HAp) and tricalcium phosphate (β-TCP) were formed by reaction sintering of HAp and brushite. Analyses of the reaction by TG, DTA and other methods revealed that several reaction steps were involved. It was found that β-TCP formed at about 800°C and that initial stage sintering of HAp was enhanced by the presence of brushite. The ratio of β-TCP to HAp in the product can be controlled by changing the concentration of brushite in the initial mixture.
