White corundum is a kind of artificial abrasive. The content of aluminum oxide (Al2O3) is above 99%, and it contains a small amount of iron oxide, silicon oxide and other ingredients, and it is white.
The product particle size is produced according to international standards and national standards, and can be processed according to the particle size required by the user. 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 crushed by a self-grinding machine, the particles are mostly spherical particles with a dry and clean surface, which is easy to bind with a binder.
