What is “White Aluminum Oxide”?
Definition: A kind of artificial abrasive. The content of aluminum oxide (Al2O3) is more than 99%, and contains a small amount of iron oxide, silicon oxide and other components, which is white.
Product particle size is produced in accordance with 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-mill, the particles are mostly spherical particles, and the surface is dry and clean, and it is easy to bond with the binder.
White corundum is made from industrial alumina powder, smelted at a high temperature of more than 2000 degrees in an electric arc, and then cooled. It is crushed and shaped, iron is removed by magnetic separation, and sieved into a variety of particle sizes. Its texture is dense, high in hardness, and the particles form sharp corners. It is suitable for manufacturing ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing high-grade refractory materials. The code "WA" is consistent with international general standards and national standards. , Most of them are for export, and there is also a certain amount for domestic users.
