We all know that white aluminium oxide has a wide range of applications. Product granularity is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size number is F4~F220, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact-resistant. If it is processed and broken by a self-grinding machine, the particles are mostly spherical particles, the surface is dry and clean, and it is easy to bond with a binder.
White aluminium oxide micropowder is the main raw material of alumina powder, suitable for chromium oxide, etc., and is smelted at high temperature. Chromium corundum is pink in color, similar in hardness to white aluminium oxide, and higher in toughness than white aluminium oxide
Abrasives made of white aluminium oxide have good durability and high grinding smoothness. It is suitable for precision grinding of measuring tools, machine tool spindles, instrument parts, threaded workpieces and sample grinding.
White aluminium oxide In the metallurgical industry, chromite is mainly used to produce ferrochromium and metal chromium. Ferrochromium alloys are used as steel additives to produce a variety of special steels with high strength, corrosion resistance, wear resistance, high temperature resistance and oxidation resistance, such as stainless steel, acid-resistant steel, heat-resistant steel, ball bearing steel, spring steel, tool steel, etc. Metal chromium is mainly used for smelting special alloys with cobalt, nickel, tungsten and other elements. These special steels and special alloys are indispensable materials for the production of guns, missiles, rockets, ships, etc. in the aviation, aerospace, automobile, shipbuilding, and defense industries. In refractory materials, chromite is used to make chrome bricks, chrome-magnesium bricks and other special refractories.
In addition, white aluminium oxide is made from industrial alumina powder, which is smelted in an arc at a high temperature of more than 2000 degrees and then cooled. Sharp angle, suitable for manufacturing ceramics, resin bonded abrasives, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc., and can also be used for manufacturing advanced refractory materials.
