Synthesis of Calcium-Phosphate Powder from Calcium Formiate and Ammonium Hydrophosphate for Obtaining Biocompatible Resorbable Biphase Ceramic Materials
Source abstract
Abstract
Calcium phosphate powder was synthesized from calcium formiate Ca(CHO2)2 and ammonium hydrophosphate (NH4)2 HPO4 with Ca/P ratio in the initial water solutions equal to 1. The phase composition of the powders synthesized from 0.5M solutions was represented by brushite CaHPO4 · 2H2O and octacalcium phosphate Ca8(HPO4)2 (PO4)6 · 6H2O. After firing at 1100°C the phase composition of the powder was represented by calcium pyrophosphate β-Ca2P2O7 and tricalcium phosphate β-Ca3 (PO4)2. The synthesized powder can be used to obtain biocompatible resorbable biphase ceramic materials and composites with a polymer matrix.
