The new class of corundum abrasive, the revolutionary new abrasive
Characteristic of Ceramic Abrasives prepared by sol-gel method
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.
A Ceramic Abrasive in the particle size of 46# contains a billion grains. During the grinding, grains of conventional electro-melting corundum will become flat passivation after the working face being wear off, and under the action of the grinding force, it is easy for grain to fall off from the grinding wheel, which leads to a short service life. However, the whole wear process of Ceramic Abrasives prepared by sol-gel method is also the self sharpening process of abrasive grains.
During the service life, the blunt tiny grains on the surface layer will continuously expose new sharp micro-grinding edge after it falls off from the abrasive grains under the action of grinding force, which makes the grains always in a sharp situation. The grinding tools made of Ceramic Abrasives have the characteristic of long life, good self-sharp ability, high cutting efficiency, and low possibility of workpiece burning.
It is different of the grain fracture behavior of Ceramic Abrasive prepared by sol-gel method from other abrasives because of its different microstructure. The performance of Ceramic Abrasive is intergranular fracture, and the performance of conventional electro-melting corundum is wear crystal fracture. The grain toughness of ceramic corundum abrasive is much higher than that of conventional electro-melting corundum.
The chemical composition of Ceramic Abrasive prepared by sol-gel method is more pure than that of white corundum, much less impurity and higher hardness. Its uniform and fine microcrystalline structure, high roughness and micro crushing properties makes it widely used in the aspect of grinding the hard processed materials such as tool steel, all kinds of alloy steel etc.
