Ceramic abrasives prepared by sol-gel method is a kind of sintered abrasive, grain size is tiny, only 100- 500nm, hundredths of the size of ordinary corundum abrasive crystal. SG abrasive is high purity, ceramic aluminum oxide abrasive with a submicron crystalline structure deprived from a seeded gel sintering process.

SG abrasive is high purity, ceramic aluminum oxide abrasive with a submicron crystalline structure deprived from a seeded gel sintering process.   the grinding tools made of ceramic abrasive have the characteristic of long life, good self- sharp ability, high cutting efficiency, and low possibility of workpiece burning.
