Application
1. Luminescent materials: used as the main raw materials for rare earth trichromatic phosphors, long afterglow phosphors, PDP phosphors, and LED phosphors.
2. Transparent ceramics: used for fluorescent lamp tubes for high-pressure sodium lamps, read-only memory windows.
3. Single crystal: used to make ruby, sapphire, yttrium aluminum garnet.
4. High strength high alumina ceramics: used to make integrated circuit substrates, cutting tools, high purity crucibles.
5. Abrasives: used to make abrasives for glass, metals, semiconductors, plastics.
6. Lithium battery: Alumina is used as a coating for lithium battery electrodes, which can effectively play the role of heat insulation and insulation to improve safety performance; doping aluminum into lithium cobaltate to form a solid solution, stabilize the lattice, and improve performance and cycle performance.
7. Others: used as active coatings, adsorbents, catalysts and catalyst carriers, vacuum coating, special glass raw materials, composite materials, resin fillers, bioceramics, etc.
