Brown corundum abrasive undergoes medium temperature calcination, resulting in pure quality, higher cleanliness, better hydrophilicity, smaller expansion coefficient, higher toughness, lower magnetic content, and stronger strength, which can significantly improve the grinding efficiency and accuracy of the grinding tool.

1. Improved hydrophilicity and strong compatibility with ceramic binders;

2. Low coefficient of thermal expansion, no mesh cracks or rust spots after making ceramic grinding tools;

3. Improved toughness and strength, significantly improved grinding efficiency and durability.
