摘要
用粉末-烧结法制备了钙磷酸盐微晶玻璃,通过DTA,XRD,SEM测试探讨了材料的制备过程、相组成及显微结构。玻璃粉末在烧结的同时进行晶化,热处理后得到了主晶相为β-Ca3(PO4)2和β-Ca2P2O7的微晶玻璃,随着烧结温度的提高,β-Ca2P2O7的含量先减小后增大,950℃烧结的微晶玻璃中β-Ca2P2O7的含量最大。实验结果表明,用粉末-烧结法可制得具有生物活性晶相的钙磷酸盐微晶玻璃。
Calcium phosphate glass-ceramics was prepared by powder-sintering method. The preparation process, phase composition, microstructure and bioactive were studied by DTA, XRD and SEM methods. When powder compacts of the glass were heated, the β- Ca3(PO4)2 and β- Ca2P2O7 phases were precipitated in the glass. The content of β- Ca2P2O7 crystalline was attected by the sintering temperature in the glass-ceramics. The largest content of β-Ca2P2O7 was precipitated in the glasses at 950℃ . The results indicate that the glass-ceramics with bioactive crystalline phase can be obtained by powder-sintering method.
