Aluminium Oxide is a raw material used in the production of advanced ceramics. In the process of oxidization, oxygen molecules form a powerful bond with the aluminium, making aluminium oxide the hardest of all oxides.

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 ceramics are products made from the chemical compound with the same name, alumina ceramic.

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.

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.

The production of alumina ceramics has something in common with the production of traditional ceramics.

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.
