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.

Alumina ceramic beads can be used in the grinding of lithium batteries. This is an emerging industry. alumina ceramic beads can show their charm through their own materials.

In fact, the alumina ceramic normal pressure sintering method is the entire process of sintering the green body under atmospheric conditions. This method will have a higher sintering temperature, so the requirements for the kiln are higher, and energy is wasted. It is also very large.

Industrial ceramic is a polycrystalline inorganic material, generally composed of grains, grain boundaries, pores and so on. In general, the opacity of ceramics is caused by the discontinuity of the refractive index between the grains due to the randomness of the non-equiaxed crystal grains in the alignment orientation, and the scattering caused by factors such as grain boundary effects and pores.

Nowadays, the refining technology of alumina ceramic parts has been continuously improved, and it has been used more and more in daily life.

Corundum castable and corundum mullite castable are common amorphous refractory materials, which is better, corundum castable or corundum mullite castable, which can be used for lining of various high-temperature industrial kilns? The difference between corundum castable and corundum mullite castable needs to be known before knowing which is better.
