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 avoid secondary pollution of alumina powder
Alumina powder is the main raw material for abrasives such as white corundum sand. If the materials used to hold the alumina powder are not clean or the packaging is unqualified, impurities will enter the alumina powder, causing differential secondary pollution and affecting its use Effect, in order to make
