High temperature calcined brown aluminum oxide


Calcined Brown Aluminum Oxide shows blue after calcination at 1350 temperature. The impurities existed in the grains will be separated out & vaporized . The surface of each particle changes coarser, improves the hydrophilicity greatly. After 1350 calcinations ,cracks from crushing and crystal cooling process be closed ,the toughness,strength is some better than normal BFA and enhancing the wear resistance too.
