This paper considers the possibility of obtaining refractory heat-resistant ceramics for high-temperature applications. The paper analyses the properties of ZrO₂ based ceramic materials that were produced using various techniques for obtaining heat-resistant refractory ceramics. Due to the use of various techniques, the authors were able to understand how such materials can be improved. It is through structural optimization that higher refractoriness and heat resistance of zirconia material stabilized with yttrium, magnesium, and calcium oxides were achieved. To produce the composite material, a cost-saving molding method was used — i.e. uniaxial pressing with additional compression in the isostatic press. The paper describes the results of a study that looked at the relationship between the chemical composition of ZrO₂ ceramic materials and the chemical resistance and physical properties of ceramic refractory sectors operating at T_max of more than 2,000 ^oC.
