brown fused alumina

High temperature Blue fired calcined brown fused alumina aluminum oxide emery powder Blue fired Calcined Brown fused alumina 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

Blue fired alumina F12-F220 for bonded abrasives Blue fired alumina 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.
