1:Introduction:
Brown corundum(A) is manufactured from bauxite with anthracite and iron scurf fused at high temperature of over 2000C.
It has the advantages of high purity and hardness,good toughness,low line expansion and corrosion resistance.
2:Applications:
It has been widely used to make bonded and coated abrasive tools,wet or dry blasting, superprecision grinding and polishing, high quality refractory materials, malleable cast iron,hard bronze and semi-conductor materials.
