- Аннотация: Powder mixtures of b-tricalcium phosphate b-Сa3(РО4)2 and potassium hydrogen sulfate КНSO4 homogenized under mechanical activation in acetone medium in planetary mill were used for producing of ceramics in K2O-CaO-SO3-P2O5 system. Powder mixtures were prepared at molar ratios of Сa3(РО4)2/KНSO4 established as 7/2, 4/2 and 1/2.According to XRD analysis data b-tricalcium phosphate b-Са3(РО4)2 was the main phase inall powder mixtures after treatment in planetary mill in acetone media. Only powder mixture «1/2» has slight quantities of additional phases. K8H9(SO4)7PO4 and K4H5(SO4)3PO4 werefound additionally to b-tricalcium phosphate b-Са3(РО4)2 in powder mixture «1/2».According XRD analysis after firing at 800oC phase composition ofceramic samples «7/2» and «4/2» contained potassium calcium phosphate Ca10K(PO4)7, β-calcium pyrophosphate β-Ca2P2O7 and calciolangbeinite K2Ca2(SO4)3. Phase composition ofceramic samples «1/2» contained calciolangbeinite K2Ca2(SO4)3, β-calcium pyrophosphate β-Ca2P2O7 and potassium sulfate K2SO4. Up to our knowledge all phases of prepared ceramic samples are biocompatible. It should be noted that potassium sulfate K2SO4 presented in ceramics «1/2» is water soluble salt.Acknowledgements: The financial support of RFBR project # 20-03-00550.Key Words: calciolangbeinite; potassium calcium phosphate; potassium sulfate; calcium pyrophosphate; ceramics
