White fused alumina is got by fusing calcined alumina in an arc
electric furnace under carefully
WA-REF is kind of refractory grain with white color, high purity,
less heat, acid & alkali proof, high
temperature resistance and good thermal stability.
WA-REF is used for making high purity refractory shapes, basic
material for corudum-mullite refractory products and casting
