Calcined Brown Aluminum Oxide

After calcinations at a certain temperature according to different grit numbers and subsequent processing, the organic matters inherent in the abrasives will vaporize and the abrasive will have higher purity, cleanliness, stronger hydrophilicity, smaller expansion coefficient, higher toughness, lower content of magnetic material and higher strength.

Typical Chemical analysis in wt.% (F24):
