White fused alumina \ white aluminum oxide (WA)
•Introduction
White aluminium oxide is electrically fused in the furnace with high grade bayer processed alumina as raw material..It has high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency,acid and alkali resistance,good thermal stability.
