Description:

White fused alumina is got by fusing calcined alumina in an arc electric furnace under carefully

controlled condition.

WA-REF is kind of refractory grain with white color, high purity, less heat, acid & alkali proof, high

temperature resistance and good thermal stability.

Applications:

WA-REF is used for making high purity refractory shapes, basic material for corudum-mullite refractory products and casting industry.
