Sol-gel corundum grain F24 F36 F46
Introduction of Sol-gel corundum grain F24 F36 F46
Ceramic Alumina abrasive grain is featured for its extream tiny crystal size and durability.It is also be called SG abrasive grain or ceramic alumina. Ceramic alumina grain is made by a sol-gel method instead of fusing process. The main structure of ceramic alumina grain is
α-Al2O3. White color and blue color sol-gel alumina grains are made from different seeded formulas. The white one is of higher aluminum oxide purity. And white color is more suitable for vitrified boned abrasive wheels.
