Calcium phosphate glass-based materials in the pyrophosphate region are briefly reviewed. Calcium pyrophosphate glasses can be prepared by including a small amount of TiO(2) (<or=10mol%). Bonelike apatite forms on some of the glasses in simulated body fluid. By heating powder-compacts of the glasses, they are crystallized and subsequently are sintered, resulting in fabrication of high-strength glass-ceramics with machinability; they are easier to be machined using conventional tools in comparison with conventional calcium phosphate ceramics. beta-Ca(2)P(2)O(7) crystal formed in the glass-ceramics plays an important role in the machinability. Their apatite-forming ability in simulated body fluid is drastically enhanced after autoclaving in distilled water. The glass-ceramics can be easily coated on a new beta-type titanium alloy using a conventional glazing technique.
简要综述了焦磷酸盐区域内基于磷酸钙玻璃的材料。焦磷酸钙玻璃可通过加入少量TiO₂（≤10mol%）来制备。在模拟体液中，某些此类玻璃表面会形成类骨磷灰石。通过加热玻璃的粉末压块，它们会结晶并随后烧结，从而制造出具有可加工性的高强度微晶玻璃；与传统磷酸钙陶瓷相比，使用传统工具加工它们更容易。微晶玻璃中形成的β-Ca₂P₂O₇晶体在可加工性方面起着重要作用。在蒸馏水中高压灭菌后，它们在模拟体液中的磷灰石形成能力会大幅增强。使用传统的釉面技术，微晶玻璃可以很容易地涂覆在新型β型钛合金上。
