    FUNKCE

    Druh umělé abrasive.3 obsahu oxidace 2 hlinitého (AI2O3), více než 98%, a prostředek, jako je, obsahujícího malé množství oxidu železitého, oxidu křemičitého, appera bílé.
    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.
