Abstract
Solid phases have been synthesized in Ca(NO3)2–(NH4)2HPO4–gelatin–H2O systems with the variable ratio Ca/P and variable pH at biopolymer concentrations of 0–2 g/L. Physicochemical studies show that calcium phosphate and gelatin based composites precipitate under our experimental conditions. The mineral composition and the amount of organic component in the precipitate are dictated by pH in the initial reaction system. The dissolution rates of composites in 0.9% NaCl are found to be two to three times the value for stoichiometric hydroxylapatite (HA) and increase in going to samples containing octacalcium phosphate (OCP) and brushite.
