Wear-resistant precision ceramic rods are compounds between metal and non-metal elements. Representative precision ceramic materials are mostly oxides, nitrides, and carbides. For example, zirconia precision ceramics and alumina precision ceramics are composed of ceramics made from clay minerals, cement, and glass, which are typical electrical and thermal insulators and more resistant to high temperatures and corrosive environments than metals and polymers.

1、Wear resistance: Wear-resistant precision ceramic rods are mainly made of high-purity alumina as the main material, and special sintering processes are used to produce precision ceramic materials. The alumina content exceeds 90%, and the hardness reaches HRA90 or above, second only to diamond, with excellent wear resistance.

2、Corrosion resistance: Wear-resistant precision ceramic rods are stable α-alumina formed by alumina powder at a high temperature of about 2000℃, with stable chemical properties and difficult to react with acids and bases. Therefore, it can resist most acid and alkali corrosion. High temperature resistance: Wear-resistant precision ceramic rods are originally sintered in a high-temperature environment and can work normally in an environment of over 1000 degrees.

3、Abrasion resistance: The inner lining of the wear-resistant precision ceramic rod has high smoothness and small connection gaps, showing good durability for large particle abrasion and gas dust abrasion.

4、Light weight and saving manpower and resources: Wear-resistant precision ceramic rods have a small density and light weight, which is convenient for installation, transportation, and maintenance, reduces the load of supports and hangers, and saves manpower and resources.

With the development of modern science and technology, wear-resistant precision ceramic rods have excellent physical and mechanical properties, high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, thermal shock resistance, and outstanding functions in thermal, optical, acoustic, electric, magnetic, chemical, biological, and other aspects. Some properties far exceed modern high-quality alloys and polymer materials. Therefore, it has become the protagonist of the new material revolution and has broad application value and potential in industrial fields such as petroleum, chemical, steel, electronics, textiles, and automobiles, as well as many cutting-edge technology fields such as aerospace, nuclear industry, and military industry.
