- Аннотация: Powder mixtures of hydroxyapatite Са10(РО4)6(ОН)2 and potassium hydrosulfate КНSO4 were investigated to confirm possibility of creating ceramic composites with biocompatible and bioresorbable phases of tricalcium phosphate Са3(РО4)2, potassium rhenanite KCaPO4, potassium-substituted tricalcium phosphate Ca10K(PO4)7 and calcium sulfate anhydrite СаSO4. Powder mixtures of calcium hydroxyapatite Са10(РО4)6(ОН)2 and potassium hydrosulfate КНSO4 were homogenized in acetone medium in planetary mill. Powder mixtures were made with molar ratio of КНSO4/Са10(РО4)6(ОН)2 established as 2/1, 4/1 and 6/1. In fact, the following phases were found in samples after firing in interval of 700-900oC: potassium calcium phosphate Ca10K(PO4)7, potassium calcium double sulfate K2Ca2(SO4)3 and potassium sulfate K2SO4. The obtained data indicate the need to adjust the composition of the staring powder mixtures for creating of ceramic composites in the K2O-CaO-SO3-P2O5 system with adequate for the intended use in regenerative medicine phase composition and solubility.Acknowledgements The financial support of RFBR project # 20-03-00550.
