CARACTERISTICAS
Una especie de artificial abrasive.3 oxidación 2 de aluminio contenido (Al2O3) más del 98%, y la composición, tales como que contiene una pequeña cantidad de óxido férrico, óxido de silicio, APPera blanco.
white aluminium oxide a kind of high grade refractories, was made from the high quality alumina by melting above 2000 in the aluminium oxide grit electric arc furnace and cooling. It is white with the main crystal phase alphaAl2O3. 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.
