- Аннотация: The new approach to obtaining ceramic materials in the Na2O-CaO-SiO2-P2O5 system based on the binder—an aqueous solution of sodium silicate and filler—hydroxyapatite was shown in current research. After heat treatment at 500 °C and 700 °C, the ceramic samples included non-reacted hydroxyapatite Ca10(PO4)6(OH)2, β-rhenanite β-NaCaPO4 and sodium calcium silicophosphate Na2Ca4(PO4)2SiO4. An increase in temperature to 900 °C and 1100 °C allowed to obtain ceramic materials with the following phases: devitrite Na2Ca3Si6O16, β-rhenanite β-NaCaPO4, β-wollastonite β-CaSiO3, and silicon dioxide SiO2. The strength of ceramic samples rose with increasing temperature from ≈ 7.0 MPa (bending) and ≈ 7.2 MPa (compression) at 500 °C to ≈ 9.5 MPa (bending) and ≈ 31.6 MPa (compression) at 1100 °C. At the same time, the apparent density decreased from 1.71 g/cm3 to 1.15 g/cm3. The top of the compressive strength equal to 31.6 MPa was observed when the apparent density was 1.15 g/cm3. Obtained ceramics consisted of biocompatible phases, widely studied in the literature; thus, it confirms the possibility of using an aqueous solution of sodium silicate in medical materials science.
