CARATTERISTICHE
Un tipo di artificiale abrasive.3 contenuti ossidazione 2 alluminio (Al2O3) oltre il 98%, e la composizione come contenente una piccola quantità di ossido ferrico, ossido di silicio, Appera bianco.
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.
