- Аннотация: The development of resorbable composite ceramics based on the Na2O–CaO–SiO2–P2O5 systemis complicated by sensitivity of the phase composition to the initial component ratio and heat treatment conditions,which can subsequently lead to variability of the functional properties of the final product. The compositeceramics obtained in the present study from a powder mixture of tricalcium phosphate Ca3(PO4)2 andsodium metasilicate pentahydrate Na2SiO3·5H2O (molar ratio 4 : 6) and fired in the temperature range of800–1100°C had the target phase composition comprising β-rhenanite β-NaCaPO4 and sodium calcium silicateNa4Ca4Si6O18. It was shown that low-temperature ceramics with a compressive strength of up to 19 MPaand porosity of up to 55% can be manufactured using heat treatment temperature of 500°C. A temperaturerise up to 1100°C caused a twofold increase in the compressive strength accompanied by a 10% decrease inthe porosity. The ceramic materials produced in the Na2O–CaO–SiO2–P2O5 system can be recommendedas resorbable porous materials for the treatment of bone tissue defects.Keywords: tricalcium phosphate, sodium silicate, powder mixture, Na2O–CaO–SiO2–P2O5 system
