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.

磷酸盐基团对硫酸钙基骨水泥结构和性能的影响

通过从水溶液中化学沉淀合成磷酸基团含量为 5、10 和 20 mol% 的硫酸钙基粉末。通过粉末X射线衍射和红外光谱对产物进行了研究。合成的粉末用于以蒸馏水作为水泥流体制备水泥浆。研究了水泥材料的相组成、溶解度、微观结构、凝结时间和抗压强度。结果表明，合成得到了由硫酸钙和磷酸三钙组成的复合粉末材料。生产出可在临床实践中用作生物可吸收水泥以替代骨组织缺损的材料。
