摘要：

The interaction in the system CaCl2-TiCl4(HCl)-(NH4)(2)HPO4-NH3-H2O-collagen at 25 degrees C is studied by the solubility (Tanaev's residual concentrations) method and pH measurements. The conditions for the coprecipitation of calcium and titanium hydroxylapatites are found. Solid phases of calcium hydroxylapatite, titanium hydroxide, and collagen are obtained. The solid phases and the products of their calcining at 950 degrees C are identified by chemical and X-ray phase analyses and IR spectroscopy. Homogeneous phases containing mixtures of Ca-10(PO4)(6)(OH)(2) and TiO2 (rutile) are obtained.
