摘要:
制备纳米级双相磷酸钙(BCP)生物陶瓷粉体。采用溶胶-凝胶法,以(CH3O)3P和Ca(NO3)2·4H2O〖JP〗为主要原料,通过钙XRD、SEM、TEM等检测方法,探索煅烧温度及原料初始Ca/P比对产物组成以及粉体粒径的影响。煅烧温度对产物钙磷比、颗粒尺寸均有一定影响,调节反应物初始Ca/P可控制产物两相组成比例,进而调节产物生物活性、降解速度等特性。通过溶胶-凝胶法制备了粒径为50~100纳米、粒径和组成可控的双相磷酸钙粉体。
Abstract:
To prepare nano-sized biphasic calcium phosphate (BCP) bioceramic powders. BCP was prepared by a sol-gel method starting from (CH3O)3P and Ca(NO3)24H2O. The product was analyzed using XRD, SEM and TEM. The influences of the heat treating temperature and the starting Ca/P mol ratio on the composition and particle size of BCP product were investigated. The heat treating temperature had certain influence on the Ca/P mol ratio and the particle size of the product. The phase constitution which decides the bioactivity and bio-degradation of the product could be controlled by the starting Ca/P mol ratio. Nano sized biphasic calcium phosphate (BCP) bioceramic powders with range from 50nm to 100nm can be derived from sol-gel method. The particle size and the constitution of the product can be controlled by the process condition.
