White fused alumina was   made from  the high quality alumina   by  melting above2200℃in the electric arc furnace and cooling. 

/MT

White fused alumina was   made from  the high quality alumina   by  melting above2200℃in the electric arc furnace and cooling.
White fused alumina is white with the main crystal phase alpha-Al2O3. White   fused  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.

Tips :
F12-220 is macrogrits for bonded abrasive tools and sand blasting ;
F230-1200 is microgrits for coated abrasive tools and polishing and lapping;
Fine powder is produced by the ball mill with wall lines of aluminum ball or aluminum powder
