    Abstract: The invention relates to the field of synthetic materials and is industrially applicable in the manufacture of wear-resistant construction parts for use under conditions of elevated temperatures, loads, and aggressive media, for cutting and machining tools, and in medical equipment. The technical problem of optimization of the performance parameters of the material, including crack resistance, hardness, and wear resistance, is solved. The objective is achieved by the fact that a material based on zirconium dioxide, containing yttrium and obtained by directed crystallization from batch mixture melted in a cold container, contains at least two tetragonal phases whose axes of tetragonality are 80-90°. The components of the batch mixture for obtaining the material are contained in the following ratio (in mol %): yttrium oxide, 2.8-3.7; zirconium dioxide, the remainder.
