White Fused Alumina

Calcined Alumina
Calcined Alumina is a commercial Alumina or Aluminum Oxide. It is white powder. One of the outstanding characteristics of Calcined Alumina is its hardness which is 9 on mohs scale. There is board industrial field of applications for this type of alumina and number of distinctive grade are produced to meet various needs.

Identification of grades
1) Calcined Aluminum S-100 grades: White granular free flowing powder passes through 150 m.
2) Calcined Aluminum S-300 grade: White superfine powder passes though 45 micron.
3) Calcined Alumina SCM grade: It is finally ground grades consisting entirely of superfine passes through 45 micron.
4) Calcined Alumina S-300 PT: It is finely ground grade consisting entirely of superfine with surface treated.

Uses
Use as a bedding material in the heat treatment of special alloy steels, It is use as a fluxing medium in the meeting of special steels as a component of low expansion glass. It is use as a constituent of special china dazes & it is use as a raw material for the manufacture of dental porcelains. It is use for refractory application such as electrical insulators. It is use as a abrasive resistant. It is use glazing ceramic tiles.

White Fused Alumina to industrial alumina powder as raw material, in the arc by more than 2000 degrees after high temperature melting made of, by crushing and shaping, magnetic to iron, sieved into a variety of particle size, the texture of dense, high hardness, Angle.
The abrasive tools made of it are suitable for the grinding of high carbon steel, high speed steel and chilled steel. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.

Applications
1. White Fused Alumina abrasives are suitable for the beautification of various high-end products, processes or hardware products. White Fused Alumina sandblasted surface without any impurities, eliminating cleaning troubles.
2. White Fused Alumina can be used as a polisher as well as various product additives. At the same time, it can do solid and coated abrasives, wet or dry or jet sand, suitable for crystal, electronic industry, super-precision grinding and polishing and making advanced refractory materials.
3. White Fused Alumina is suitable for processing hardened steels, alloy steels, high speed steels, high carbon steels and other materials with harder hardness and greater tensile strength. Can also be used as touch media, insulators and precision foundry sand.
4. White Fused Alumina is used to remove rust, decontaminate and remove scales from iron work pieces to increase the adhesion of coatings and coatings. It is also used for the descale of aluminum work pieces, as well as surface strengthening and light decoration.
5. White Fused Alumina is also used for deoxidation of copper work pieces, matt effect, glass products crystal matte, carved pattern matte effect of plastic products, denim and other special fabric plush processing and effect patterns.

Advantage
1. the use of white Fused Alumina does not affect the color of the work piece.
2. It can be used for sandblasting in the process of forbidden iron powder residue.
3. fine powder white Fused Alumina is very suitable for wet sandblasting and polishing work.
4. The amount of iron oxide it contains is extremely low for sandblasting where iron residue is strictly prohibited.
5. it is through the pickling step to remove impurities.
