1.Introduction

 

White fused alumina is fused by alumina powder by electric arc furnace under high temperature.

It has white color and little higher hardness and lower toughness comparing with brown fused

alumina. The micro hardness of the product is 2200-2300kg/mm2. It has higher hardness and

slight lower toughness comparing with brown fused alumina. It is also characterized by its high

purity, acid and alkali resistance, good thermal stability. It’s the high grade refractory materials.
