White Alumina Oxide sand for refractory material
Price: FOB 899$/MT
Product Introduction
White alumina oxide was made from the high quality alumina by melting above 2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alphaAl2O3.
White alumina oxide produced intitling electric arc furnace has the adwantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.
Chemical and physical parameters
Model&Application
White alumina oxide in complete model of 8-5mm,5-3mm,3-1mm,1-0mm etc.
20mm MAX . Customized size is accepted with pleasure
Suitable for fire-proof materials and other high temperature material and usually used in smelting factory,industrial furnace, etc.
