Since its establishment in 2002, Jinzhou Yunxing Industrial Ceramics Co., Ltd. will carry out the largest one-time investment and construction project-the corundum ceramic project this year. The first phase of the project was officially launched today.

The Rockwell hardness of alumina ceramics‍ is HRA80-90. The hardness of alumina ceramics is second only to that of diamond, which far exceeds the wear resistance of wear-resistant steel and stainless steel.

Piezoelectric ceramics have piezoelectric effect. As a new functional material, high temperature piezoelectric ceramics are widely used in many special fields such as aerospace, nuclear energy, metallurgy, petrochemical industry, geological exploration, etc.

Alumina ceramicsare divided into two types: high-purity and ordinary.

After the powder is formed, a biscuit with good shape is obtained, and then the biscuit is heated at a certain temperature. The biscuit undergoes volume shrinkage and finally becomes a compact sintered body. This process is called sintering. The driving force of alumina ceramic green body sintering is mainly the change of powder surface energy, that is, the surface energy of powder decreases, the surface area decreases, and the ceramic densifies. In the process of ceramic sintering densification, material transfer can be carried out through solid phase diffusion, including surface diffusion, grain boundary diffusion, lattice diffusion, etc. Normal pressure sintering is generally used in industry.

In the past few years, the development of industrial ceramic materials has developed to control and manipulate its specific microstructure, which will greatly expand its application scope in all walks of life. Therefore, industrial ceramics are considered to be one of the most effective materials today.

Ceramics are usually composed of commonly available materials, such as carbon, silicon, oxygen and nitrogen.
