White fused alumina(WFA), a kind of high-grade refractories, is made from the imported quality alumina by melting above 2000 c in the electric arc furnace and cooling. It is white with the main crystal phase a-AL2O3. The white alumina produced in the titling electric arc furnace has the advantage of high bulk density and low porosity, thus the volume stability and thermal shock resistance can be improved..
For Refractory:White Fused Alumina(WFA or WA)is made from chemical by Higgns furnace or Tilting furnace at high temperature.It is very important raw material for advanced refractories and abrasives.Its properties are as folowing.
