Abstract

The aim of the paper is to justify the choice of the region of the system MgO—Al2O3—TiO2—SiO2, which is promising for the production of functional ceramics under conditions of low temperature synthesis. The structure of the A3S2—M2A2S5—AT—S tetrahedron in detail is considered (Тe = 1400 °C), it found that the minimum eutectic of this region is four-component. Compositions based on the above-mentioned tetrahedron are promising for the synthesis of chemically and thermally stable ceramics. Optimization of tialite and mullite-tialite ceramics at a synthesis temperature of 1250 °C has been carried out while maintaining the ratio MgO : TiO2 = 0.18 in the raw mixtures. The dependencies of the properties of materials on the compositions of the ceramic masses were received by mathematical modeling. Mass compositions of functional ceramics in conditions of low-temperature synthesis with high performance indicators have been developing.
