Abstract

The invention discloses a compound ceramic material. The compound ceramic material is prepared from the following components in parts by weight: 80-100 parts of kaolin, 25-45 parts of silicon carbide, 6-10 parts of boron nitride, 1-8 parts of nano-zirconia, 2-10 parts of glass fibers, 1-3 parts of carbon fibers, 5-9 parts of nano-zirconium dioxide, 3-6 parts of magnesium oxide, 2-4 parts of gallium oxide, 2-4 parts of a saline coupling agent, 5-9 parts of polyethylene glycol and 5-8 parts of methyltriacetoxysilane. After being sintered at a high temperature, the compound material has the characteristics of good corrosion resistance, good thermal change tolerance, high strength, good thermal shock resistance and good impact resistance, has a certain adsorption performance, and is an environment-friendly ceramic material.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a composite ceramic material. Background technique [0002] Traditional aluminosilicate ceramics have poor purity, uneven particle size, and low molding pressure, which cannot meet market demand. With the development of ceramic manufacturing technology, the performance of ceramic materials is getting better and better. Ceramic materials have a certain porosity. Porosity can not only ensure that ceramic materials have special excellent properties, but also reduce the weight of ceramic materials. Ceramics prepared from different raw materials have different properties. How to improve the mechanical properties and thermal properties of ceramic materials Characteristics, electrical characteristics and other properties are problems that need to be further solved for ceramic materials. [0003] Composite ceramic materials have excellent properties such as high hardness, good wear resistance, ...
