Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a formulation of a high-temperature-resistant tough ceramic material. Background technique [0002] Ceramic materials are the materials with the best rigidity and the highest hardness among engineering materials, and their hardness is mostly above 1500HV. Traditional ceramics mainly use natural rocks, minerals, clay and other materials as raw materials, while new ceramics use artificially synthesized high-purity inorganic compounds as raw materials, which are made by molding, sintering and other treatments under strictly controlled conditions. Organized inorganic materials. New ceramic materials have their unique advantages in performance. In terms of thermal and mechanical properties, it has high temperature resistance, heat insulation, high hardness, wear resistance, etc.; in terms of electrical properties, it has insulation, piezoelectricity, semiconductor, magneti...
