Six Applications Of High Purity Alumina
High-purity alumina is white micropowder with uniform particle size, easy to disperse, stable chemical properties, moderate high temperature shrinkage performance, and good sintering performance; high conversion rate and low sodium content, it is generally used in the following areas:
Luminescent material: used as the main raw material of rare earth tricolor phosphor, long afterglow phosphor, PDP phosphor and LED phosphor;
Transparent ceramics: used as fluorescent tubes for high-pressure sodium lamps, electrical programmable read-only memory windows;
Single crystal: used to make ruby, sapphire, yttrium aluminum garnet;
High-strength and high-alumina ceramics: used in the manufacture of integrated circuit substrates, cutting tools, and high-purity crucibles;
Abrasives: abrasives used in the manufacture of glass, metals, semiconductors, plastics;
Others: High-purity alumina can also be used as active coatings, adsorbents, catalysts and catalyst carriers, vacuum coating, special glass raw materials, composite materials, resin fillers, bioceramics, etc.
