Abstract
The interaction in the CaCl2-AlCl3-(NH4)(2)HPO4-NH3-H2O-collagen system at 25 degreesC was studied by the solubility method (the Tananaev method of re sidual concentrations) and pH measurements. The conditions for coprecipitat ion of calcium hydroxyapatite (HAP) with collagen and of calcium hydroxyapa tite with aluminum hydroxide and collagen were found. Collagen-containing c alcium hydroxyapatite and homogeneous mixed phases containing tricalcium ph osphate (TCP), aluminum hydroxide, and collagen or calcium hydroxyapatite, aluminum hydroxide, and collagen were obtained. The isolated solid phases a nd the products of their calcining at 900 degreesC were studied by chemical analyses, X-ray powder diffraction, and IR spectroscopy.
