Tabular Alumina
Tab Alumina’s raw material is industry Al2O3 powder. After grinding, forming to balls and drying, it is rapidly heated in the ultra-high temperature shaft kiln of 1950 ±20℃, then cooling down to get the dense crystal balls. Tab Alumina has high purity, high refractoriness, high hardness, good thermal shock stability, good erosion resistance and abrasive resistance. Widely used in steel, casting, petrochemical, castable, ceramics and other high-performance refractory materials.
White Fused Alumina
White Fused Alumina based on industry Alumina Powder, smelting by tilting furnance or fixed furnance. WFA color is pure white, hardness is good, good property on acid and alkali resistance. abrasion resistance, anti-resistance and volume stability good at high temperature. It's one of the most important raw materials for high grade abrasive and refractory materials.
Brown Fused Alumina
Brown Fused Alumina use bauxite as raw material, through 2200 ℃ tilting furnance or fixed furnance electric fusion. Tilting furnance BFA color shows dark brown, fixed furnance BFA color shows dark brown with little bit red. BFA shows high hardness, toughness, it is an very important raw material for refractory and abrasive applications.
