Abstract

The invention provides a high-strength and high-toughness ceramic material, which is prepared from the following raw materials: zirconite, kaoline, a fibrous material, silicon carbide, titanium dioxide, a composite admixture, aluminum nitride, calcium carbonate, a toughening agent, a foam stabilizer, acetate and a cosolvent. The high-strength and high-toughness ceramic material provided by the invention has good bending strength, fracture toughness and impact resistance, and is excellent in thermal stability and corrosion resistance; the high-strength and high-toughness ceramic material also has excellent high temperature resistance and thermal shock resistance, so that alumina titanate ceramics can be used in practical applications; therefore, the high-strength and high-toughness ceramic material can be widely applied to industrial production.

Description

technical field [0001] The invention relates to the technical field of ceramic inorganic non-metallic materials, in particular to a high-strength and high-toughness ceramic material. Background technique [0002] Ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds after forming and high-temperature sintering. They have high melting points and excellent chemical stability at high temperatures; their thermal conductivity is lower than that of metal materials, but still good. When the temperature changes, ceramics have good dimensional stability. Ceramic materials are not easy to oxidize at high temperatures, and have good corrosion resistance to acids, alkalis, and salts, and have high wear resistance and oxidation resistance. And other advantages, can be used as structural materials, tool materials. In terms of thermal and mechanical properties, ceramic materials have the advantages of high temperature resistance, heat in...
