摘要
研究了硼硅酸盐玻璃(0B、1B和H12)的组成在0.25M K2HPO4水溶液中对其模拟矿化能力的影响。采用X衍射、傅立叶红外和扫描电镜技术分析了矿化产物的晶体结构和形貌特征。结果表明:三种玻璃均矿化形成了碳酸羟基磷灰石(HCA)片状晶体,并交叉堆积排列呈多孔网络结构;1B玻璃形成的HCA晶体堆积密集、晶化较完全;0B玻璃形成的HCA晶体堆积疏松、晶化不完全;H12玻璃则位于两者之间。综合分析表明,B和Na元素使玻璃矿化能力增强,Al元素使玻璃矿化能力减弱。
The mimetic mineralization ability of three kinds of borosilicate glasses （designated 0B, 1B and H12） immersed in 0.25M K2HPO4 aqueous solution was investigated. The structures and morphologies of the mineralized products were characterized using XRD, FTIR and SEM techniques. The results showed that the glasses have were converted to plate-like carbonated hydroxyapatite（HCA）crystals, and the overlapping arrangement assumed the porous structures. The crystallization of the HCA was more complete and more compact in stacking arrangement for 1B glass, less for 0B glass and between the both for H12 glass. The comprehensive analysis indicate that the boron and sodium element promotes mineralization, conversely, the aluminum element inhibits it.
