通过添加少量 TiO2 制备了含有 P2O72− 和 PO43− 离子的磷酸钙反相玻璃。在 37°C 温度下的模拟体液 (SBF) 中检查磷酸盐倒置玻璃表面骨状磷酸钙磷灰石的形成。浸泡20 d后，6CaO·3P2O5·TiO2反相玻璃上沉积有叶状磷灰石颗粒（基于摩尔比）。与偏磷酸盐玻璃相比，该玻璃对 SBF 具有更高的化学耐久性； P离子没有从6CaO·3P2O5·TiO2玻璃中过量溶解，因此磷灰石的形成没有受到抑制。
Calcium phosphate invert glasses, which contain P2O72− and PO43− ions, have been prepared via the addition of a small amount of TiO2. The formation of bonelike calcium phosphate apatite on the surface of the phosphate invert glasses was examined in simulated body fluid (SBF) at a temperature of 37°C. Soaking for 20 d resulted in the deposition of leaflike apatite particles on 6CaO·3P2O5·TiO2 invert glass (based on molar ratio). The glass had much-greater chemical durability against SBF, in comparison with a metaphosphate glass; P ions were not dissolved excessively from the 6CaO·3P2O5·TiO2 glass, so the apatite formation was not suppressed.
