What is corundum

White fused alumina powder as raw materials in industry, at more than 2000 degrees by arc melting temperature after cooling is made by crushing plastic, magnetic separation to iron, sieving into a variety of particle size, its texture is dense, high hardness, grain formation of sharp corners form for use in manufacture of ceramics, resin bonded abrasives and grinding, polishing, sandblasting, precision casting (casting special corundum), etc., can be used to manufacture high-grade refractories, code-named "WA" on internationally accepted standards, national standards , the majority for export, there is a certain amount of supply domestic users.
Particle size in accordance with international standards and national standards of production, processing granularity according to user requirements. General size number of F4 ~ F320, depending on its chemical composition and different particle sizes. Prominent feature is the small crystal size, impact resistance, if the self-processing mill crushed particles are mostly spherical particles, dry surface cleaning, easy binding agent combination.
Corundum density:
Density is divided into two, one corundum bulk density, the second is the true density corundum.
