White Fused Alumina
White Fused Alumina ,high grade refractory material,is made from high quality alumina by melting above 2000 in the eletric arc furnance.
Characteristic
1.It has higher hardness and slightly lower toughness compared with brown fused alumina.
2. It is also characterized by its high purity, ability of self-sharping , better cutting ,less heat emit ,higher efficiency ,acid and alkali resistance ,good thermal stability.
