Abstract
Calcium sulfate-based powders with contents of phosphate groups of 5, 10, and 20 mol % were synthesized by chemical precipitation from aqueous solutions. The products were studied by powder X-ray diffraction and IR spectroscopy. The synthesized powders were used to prepare cement pastes with distilled water as a cement fluid. The phase composition, solubility, microstructure, setting time, and compressive strength of the cement materials were studied. It was shown that the synthesis gave composite powder materials consisting of calcium sulfate and tricalcium phosphate. Materials that could find use in clinical practice as bioresorbable cements to replace bone tissue defects were produced.
