- Аннотация: Powder mixtures of hydroxyapatite Са10(РО4)6(ОН)2 and potassium hydrosulfate КНSO4 wereinvestigated to confirm possibility of creating ceramic composites with biocompatible andbioresorbable phases of tricalcium phosphate Са3(РО4)2, potassium rhenanite KCaPO4, potassiumsubstituted tricalcium phosphate Ca10K(PO4)7 and calcium sulfate anhydrite СаSO4. Powdermixtures of calcium hydroxyapatite Са10(РО4)6(ОН)2 and potassium hydrosulfate КНSO4 werestudied to reveal processes taking place under heating. STA 409 PC Luxx thermal analyzer(NETZSCH, Germany) were used in experiment.In fact, the following phases were found in samples after firing in interval of 700–900 °C:potassium calcium phosphate Ca10K(PO4)7, potassium calcium double sulfate K2Ca2(SO4)3 andpotassium sulfate K2SO4. The obtained data indicate the need to adjust the composition of thestaring powder mixtures for creating of ceramic composites in the K2O–CaO–SO3–P2O5 systemwith adequate for the intended use in regenerative medicine phase composition and solubility.Acknowledgements The financial support of RFBR project # 20-03-00550.
