Alumina is a very chemically ionized substance with a high melting point, hardness and high chemical stability, especially it can maintain high hardness and strength at high temperatures, and this AlO is widely used. Used in metallurgy, machinery, chemical industry, electronics, medicine, aviation and national defense. Due to the ultra-micronization of alumina powder, its surface electronic structure and crystal structure have changed, resulting in surface effects that macroscopic objects do not have. , Small size effect, quantum effect and macroscopic quantum tunneling effect.
How to control the quality and effect of alumina powder
White corundum is the most suitable raw material for obtaining alumina powder, but the first step is to destroy it to a certain extent through a drum destroyer. Considering that there are many impurities in the raw materials, pickling and water washing are needed after destruction to effectively remove the
