Brown Fused Alumina is made from reduced fusion of quality bauxite,iron and coal in electric arc furnace under 2500 degrees
Refractory
Because of its high purity,high cleanliness,coarse grain, low magnetic contents,high density,high bulk density,chemical stability,low porosity rate,nice crystal structure,corrosion and acid resistant,no cracks, corrosion or spot during production of refractory products,is a mineral for shaped and unshaped refractory products in fire-proof,precision casting,foundry and coating industries.
Abrasive Tools and Sandblasting
Brown Fused Alumina,made according to FEPA,JIS Standard etc.with its hardness,toughness,sharp edge andself-sharpening character,is an ideal synthetic abrasives material for production of abrasive tools,sand blasting and surface treatment.
