In order to prolong the service life of high purity alumina furnace tubes and reduce the losses caused by damages due to improper use, the following suggestions are hereby put forward for users' reference

The last order before the Spring Festival holiday was a custom alumina ceramic ring. Production was originally planned to begin after the holidays. Due to the outbreak of the virus, we extended our holidays and we were unable to process ceramic rings on time.

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.

Do nucleic acid on time, actively respond to home isolation, do not go out without contact, wear a mask when going out, and do a good job of disinfection and disinfection and sterilization when going home.

Main products: alumina ceramic, alumina ceramic tube, alumina furnace tube, alumina crucible, alumina ceramic beads, alumina ceramic plate, alumina ceramic rods, alumina ceramic parts, industrial ceramic, thermocouple tube, Alumina Ceramic Tube, Alumina Ceramic Crucible, Alumina Ceramic Plate , Alumina Ceramic Beads, Alumina Ceramic Rods, Alumina Ceramic Parts.

Alumina Ceramic Crucible is mainly made of zirconium dioxide. It is fired at high temperature with a special formula. It is a refractory with high fire resistance. It can withstand temperatures of 1800 degrees Celsius and high temperature resistance. It is usually used for smelting precious metals, nickel And other metals, with excellent chemical resistance and high temperature resistance.
