Product Details
Description:
White fused alumina is got by fusing calcined alumina in an arc electric furnace under carefully controlled condition.
WAREF is kind of refractory grain with white color, high purity, less heat, acid & alkali proof, high temperature resistance and good thermal stability.
WALN is kind of low sodium cotent refractory grain with white color, high purity, less heat, acid & alkali proof, high temperature resistance and good thermal stability.
Applications:
White fused alumina is used for making high purity refractory shapes, basic material for corudum-mullite refractory products and casting industry.
