Abstract—

To produce materials based on the P₂O₅–CaO–TiO₂ system, we have prepared film-forming solutions of four compositions, containing 70, 75, 85, and 95 wt % titanium(IV) oxide. The suitability of the film-forming solutions for film growth has been shown to be limited to viscosity values in the range from 3.4 to 3.7 mm²/s. At 70 and 75 wt % titanium(IV) oxide, a CaTiO₃ (perovskite) phase has been identified in the P₂O₅–CaO–TiO₂ system. The most uniform deposition of particles, with a large number of open pores after immersion in simulated body fluid (SBF), has been observed at 70 and 75 wt % titanium(IV) oxide. These compositions are thus the best suited for practical application.

TiO 2含量对薄膜磷酸钙材料合成及理化性能的影响

摘要—

为了生产基于P ₂ O ₅ -CaO-TiO ₂系统的材料，我们准备了包含70、75、85和95 wt％氧化钛（IV）的四种成分的成膜溶液。已经表明成膜溶液对膜生长的适用性限于在3.4至3.7mm ² / s的范围内的粘度值。在70％和75 wt％的氧化钛（IV）下，在P ₂ O ₅ –CaO–TiO _{2中发现了}CaTiO ₃（钙钛矿）相。系统。浸入模拟体液（SBF）后，在70％和75 wt％的氧化钛（IV）下观察到了最均匀的颗粒沉积，并带有大量的开孔。因此，这些组合物最适合实际应用。
