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.
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.
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.
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.
A good alumina ceramic product needs a good molding process. A good molding process can obtain a good green density. The green density affects the ceramic density and the ceramic performance.
With the development of society, some aspects of metal materials can no longer satisfy our better production and life. New materials have emerged, among which alumina is the most common one. Alumina ceramics are made by sintering alumina materials.
