  In the broad field of materials science, alumina family has become a hot spot of research and application because of its huge member system and diversified characteristics. Each member of this family has a unique preparation "code", such as alpha-alumina, which needs to be calcined in a high-temperature furnace at about 1300 ° C to show its excellent heat resistance and chemical stability; Gamma-alumina, on the other hand, has chosen a milder path, forming at relatively low temperatures of about 500 ° C and exhibiting unique physical and chemical properties. In addition, the performance of doped modified alumina can be customized by skillfully introducing iron, chromium, lanthanum and other elements. The high-purity alumina is like an artist who has the ultimate pursuit of purity, strictly excluding all external impurities.   In the face of such diverse alumina production needs, the  alumina tray , the vehicle in the calcination process, plays a crucial role.
