Abstract

The invention relates to a wear-resistant ceramic tube and a preparation method thereof and belongs to the technical field of production of ceramic materials. The wear-resistant ceramic tube comprises the following components in parts by weight: 30-50 parts of silicon oxide, 40-55 parts of aluminum oxide, 10-20 parts of aluminum nitride, 10-20 parts of yttrium oxide and 0.5-10 parts of silicon carbide. The preparation method comprises the following steps of weighting raw materials, mixing, stirring, drying in vacuum, ball milling, sieving, carrying out dry pressing and cold isostatic pressing, removing binder and carrying out pressureless sintering. The ceramic tube has the characteristics of good wear resistance, few air pores and good density.

Description

technical field [0001] The invention relates to a ceramic tube and a preparation method thereof, in particular to a wear-resistant ceramic tube and a preparation method thereof, and belongs to the technical field of ceramic processing. Background technique [0002] Ceramic material is the most important kind of inorganic non-metallic materials that people pay attention to after metal materials and non-metallic polymer materials, because it has the common advantages of both metal and polymer materials, and is constantly being modified. In the process, its brittle performance has been greatly improved. [0003] The word ceramics (Ceramics) comes from the word Keramos in ancient Greece, which means the god of the earth. Traditional ceramic materials have a wide range of meanings and are relatively complicated. It mainly refers to nitrides, carbides, glass and silicates of aluminum and silicon. kind. Their main feature is that they are hard and crystalline, but brittle. Tradi...
