Ceramic Abrasive Grain


Ceramic abrasive grain is a sintered abrasive made by sol-gel method with special alumina as the main raw material and various modified components. Each individual ceramic abrasive has a very small grain size of only 100-300 um, which is a few percent of the crystal size of ordinary corundum abrasive grains. Ceramic grain alumina can be applied to bonded abrasives, coated abrasives and other special abrasive tools, which has much higher performance than fused alumina abrasives in the specification of hardness, strength, toughness and friability etc. Its grain containing hundred thousand and even ten million of alumina micro crystals instead of only a few crystals in the grain of the fused alumina abrasive, and its macro crystal falling off accordingly in the grinding process, and that’s why ceramic abrasive grain can multiply increase the life and efficiency of the abrasive tools and have the advantages of machining accuracy and cool cutting as well.


We have produced three product ranges and micro-powder, including BSG, WSG and WSG-1. BSG (blue) has stacked nanosheet structure, which can satisfy requirements of physical specifications in difference applications. WSG and WSG-1 have polyhedron structure, in which WSG-1 is strongly recommended since it can be applied to replace super abrasive competitively.

BSG: Blue Sol Gel Abrasive Grain

WSG 1: White Sol Gel Abrasive Grain- the Substitute of Diamond and CBN

WSG1 is a brand new sogel abrasives.It is unique in the world developed by us.It is especially strongly recommended since it can replace the super abrasives diamond & CBN competitively.

Product Property


Recommended Apllications

  • It is suitable for making resin bond, vetrified bond and metal bond abrasives(replacement of Tungsten alloy).

  • It is suitable for high material removal ratio, e.g. bearing.
