The paper raises questions about the search for the possibility of obtaining a construction ceramic material using a special type of raw material component. Diopside concentrate was chosen as the basis for the ceramic masses due to its positive parameters necessary to improve the strength properties of the material and to support local deposits of raw materials in the East Siberian region. To reduce the optimal firing temperature, an aqueous-alkaline solution of sodium silicate was used in small quantities. The chemical composition of the diopside rock showed mainly the presence of silicon oxides. X-ray diffraction analysis revealed the presence of diopside, quartz and calcite. Sodium-silicate glass is characterized by a full content of silica and a modulus of 3. Using the state diagram of three-component systems, the temperature limits necessary for sintering ceramic masses are established. The fusibility curves show that at a temperature of 1040oC, the values of the primary melt for various compositions are 4-14%, and the total melt content is observed at 1475oC. The parameters of physical and mechanical properties of the ceramic material were determined, where at the firing temperature of 1000-1100oC the value of fire shrinkage was no more than 1%, water absorption up to 10%, and compressive strength up to 31 MPa. Moreover, with an increase in the amount of diopside to 90% by weight, the strength increases, and shrinkage decreases. X-ray phase analysis of the compositions determined mainly analytical lines of diopside, which begin to decrease by 1000oC, which determines the relationship with the liquid glass. The DTA and TG curves of the thermogram showed endothermic and exothermic effects due to the release of adsorbed water and crystallization of glass. The possibility of obtaining high-strength low-shrink ceramics using diopside raw materials as the basis of ceramic masses when adding sodium-silicate glass in the form of a melt is established.
