White Corundum Refractory Material

white corundum refractory material 1. Description:white corundum, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3.The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.2.Chemical compositions and physical properties:white corundum refractory material Model: White Corundum100FChemical compositionsPhysical propertiesItemsValue of specification (%)itemsPropertyAl2O398.50minColorWhiteNa2O0.50maxBulk density1.75-1.95g/cm3CaO0.50maxGrain density3.90g/cm3minContent of magnetic substance0.03maxMorse hardness93.Application:It is usually used for refractory material. 4.About us:Henan Sicheng Co., Ltd, founded in 1999,is specialized in White Fused Alumina, Brown Fused Alumina, Mullite and other related products.
