Beyaz Erimiş Alümina/Beyaz Alümina Oksit/Beyaz Alüminyum Oksit/Beyaz Korindon/Beyaz Elektrik Korindon/WFA

White Fused alumina was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.
It is white with the main crystal phase α-Al2O3.
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.
