- Аннотация: Silicon carbide is a promising material for heat-loaded units due to its high strength at elevated (up to 1500 °C) temperatures and excellent thermal conductivity. Silicon carbide ceramics is widely used for structural applications, yet production of such materials belongs to extremely energy-consuming industries, thus it becomes an important task to carefully adjust ceramics compositions and methods of manufacturing.The present paper discusses the correlation between mechanical behaviour (dependent variable, calculated as single contact strength) and process parameters (independent variables), namely sintering aid type, amount and preparation technique (solid-state synthesis combined with heterophase co-precipitation or microwave-assisted drying), green body pressure value, and fine fraction content for SiC-based compositions with oxide sintering aids in ternary systems CaO - Al2O3 - Y2O3 (CAY) and MgO - Al2O3 - Y2O3 (MAY) respectively. The experimental data were processed by statistical methods and the conclusions concerning complex influence of factors on ceramics properties were done based on the calculated effects of factors.The research was carried out within the framework of a full factorial design where independent variables were varied on two levels and regression models for SiC - CAY and SiC - MAY ceramics were constructed
