| Abstract: | The CaCl2-(NH4)2HPO4-C8H11O7Na-NH3-H2O system was studied at 25°C using the solubility method (Tananaev’s residual concentration method) and pH measurements. The solid phases isolated from the system were characterized using chemical analysis, X-ray powder diffraction, IR spectroscopy, and thermogravimetry. Nanocrystalline carboxymethylcellulose-containing calcium hydroxylapatites Ca10(PO4)6(OH)2 · xH2O · yC8H11O7Na with x = 6–12 and y = 0.1–0.5 were found as a result of the characterization. |
