What are the methods of making corundum

Corundum structure is very special, and general usage of corundum is different, following a brief introduction about the purpose of corundum .
Corundum high quality bauxite as raw material, anthracite , iron Xiao , in the arc melting temperatures above 2000 degrees by made ??by shaping from the mill grinding , magnetic separation to iron , sieving into a variety of particle size , its dense texture , hardness high formation of spherical particles , for the manufacture of ceramic , resin high abrasive and grinding, polishing , sandblasting, precision casting , etc., can also be used to manufacture advanced refractories .
Corundum with high purity, good crystalline liquidity, low coefficient of linear expansion , corrosion-resistant characteristics. After dozens of proven refractory manufacturer , the product in the application process has not detonate , not powder, not crack characteristics. In particular, its price is much higher than conventional corundum , and more to become the best corundum refractory aggregate and filler.
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, due to a self- processing mill broken particles are mostly spherical particles , corundum with high purity, dense texture , bulk density, self-sharpening strength , good toughness, magnetic material Features ultra-low levels , with its made of abrasive grinding sharp , low fever , grinding ratio .
