New Applications of High Purity Alumina by Hengjing New Materials


Release time:

2018-12-10

The new applications of high-purity alumina from Hengtong Crystal In recent years, high-purity alumina has expanded its role beyond being a raw material for electrolytic aluminum. Internationally, the development of high-purity alumina has been particularly rapid, with a wide range of applications. High-purity alumina appears as a white micro-powder, with uniform particle size, easy dispersion, and stable chemical properties. It also has moderate high-temperature shrinkage performance and good sintering performance conversion rate, with relatively low sodium content. This product is a basic raw material for producing heat-resistant, wear-resistant, and corrosion-resistant products. The applications of high-purity alumina also include its use in translucent alumina sintered bodies, as a carrier for phosphors, as an additive for special gases, and in sapphire production.

New Uses of High Purity Alumina from Hengtong Crystal In recent years, high purity alumina has expanded its role beyond being a raw material for electrolytic aluminum. Abroad, the development of high purity alumina has been particularly rapid, with a wide range of applications. High purity alumina appears as a white micro powder, with uniform particle size, easy to disperse, and stable chemical properties. It has moderate high-temperature shrinkage performance and good sintering performance conversion rate, with relatively low sodium content. This product is a basic raw material for producing heat-resistant, wear-resistant, and corrosion-resistant products. The applications of high purity alumina also include use in translucent alumina sintered bodies, phosphor carriers, additives for special gases, sapphires, and many other areas, making its range of applications quite broad. Other main uses include: - Luminescent materials: Used as the main raw material for rare earth trichromatic phosphors, long afterglow phosphors, PDP phosphors, and LED phosphors. - Transparent ceramics: Used for fluorescent tubes in high-pressure sodium lamps and windows for electrically programmable read-only memory. - Single crystals: Used for manufacturing rubies, sapphires, and yttrium aluminum garnets. - High-strength high-alumina ceramics: Used for manufacturing integrated circuit substrates, cutting tools, and high-purity crucibles. - Abrasives: Used for manufacturing abrasives for glass, metals, semiconductors, and plastics.
