Abstract

The invention provides a high-toughness ceramic material and a preparation method thereof and belongs to the technical field of preparation of ceramics. The high-toughness ceramic material is mainly prepared from red mud, calciclase, silica sand, kaolin, wollastonite, chromite, aramid fiber, viscose acetal fiber, carbon fiber, polypropylene fiber and polythene fiber. By the addition of the fiber components, good toughness of ceramics is achieved, shortcomings the a traditional ceramic material is high in fragility and prone to cracking are overcome, and wide market prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a high-toughness ceramic material and a preparation method thereof. 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...
