骨的无机成分为称作羟基磷灰石的磷酸钙结晶，它在中性到碱性域生成。为了得到生物活性磷酸盐玻璃，必须由PO43-和P2O74-离子构成，为此，必须导入大量二价阳离子，以连结这些磷酸盐基团。选择添加TiO2，使能结合成O-P-O-Ti-O-P-O，促进形成长链化玻璃，提高玻璃的化学稳定性， The inorganic component of bone is a calcium phosphate crystal called hydroxyapatite, which is formed in the neutral to basic domains. In order to obtain a bioactive phosphate glass, it must consist of PO43- and P2O74- ions, to which end a large quantity of divalent cations must be introduced in order to link these phosphate groups. Select to add TiO2, enable the combination of O-P-O-Ti-O-P-O, to promote the formation of long-chain glass, improve the chemical stability of the glass,
