White Fused Alumina Description

Main ingredients: Aluminum oxide content is more than 98%, and contains a small amount of iron oxide, silicon oxide, and other components. It is made by smelting in an arc at a high temperature of more than 2000 degrees and then cooling. It is crushed, shaped, and magnetically separated. After removing iron, it is sieved into various particle sizes. Its texture is dense and hard, and the particles form sharp corners.

Available Size

White Tabular Alumina

White tabular alumina is an abrasive material with a white color and no obvious impurities. It is usually prepared from aluminum oxide and has a plate-like or sheet-like form.
