Abstract

The invention discloses a high-temperature-resistant ceramic material and a preparation method thereof. The high-temperature-resistant ceramic material is prepared from, by weight, 208-233 parts of nanometer zirconium, 25-36 parts of wolfram carbide powder, 20-22 parts of mica powder, 18-20 parts of iron oxide powder, 10-14 parts of tetrapod-like zinc oxide whiskers, 50-53 parts of aluminum nitride powder, 2-6 parts of scandium oxide powder, 30-70 parts of cobalt powder, 10-15 parts of molybdenum carbide powder, 22-28 parts of silicon carbide whiskers, 6-10 parts of aluminum borate whiskers, 3-6 parts of nano-iridium and 3-8 parts of yttrium oxide powder. The high-temperature-resistant ceramic material has good heat dissipation performance.

Description

technical field [0001] The invention relates to a high temperature resistant ceramic material and a preparation method thereof. Background technique [0002] The brake disc, in simple terms, is a round disc that rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the car. Disc brakes provide better braking and are easier to maintain than drum brakes. [0003] The overheating of the brake disc of the automobile will affect the braking performance, and in severe cases, the brake will fail, and the brake will inevitably generate heat. Therefore, it is necessary to provide a brake disc with a good heat dissipation effect. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a high temperature resistant ceramic material with good heat dissipation performance. [0005] In order to solve the above proble...
