For purpose of improve the bonding behavior of grains,regular brown fused alumina could be modified the surface by ceramic coating.Thereafter,the coating will create a ligament between grains and resin.Meantime,the heat treated during process could also modify the crystal to increase the toughness of the grains.

We symbol this treatment as“CC”.

For purpose of further improve the performance of grains,regular brown fused alumina can modified the surface by ceramic coating after heat treated at 1350 centigrade(open annealed).

We symbol this treatment as“HTCC”

RBT are produced by selected the high purity bauxite with accurately fusion control which achieve lowest unstable foreign oxide and free carbon and sulfur contents.The chemical compositions of RBT strictly design for vitrified application,so that RBT is completely reliable product for vitrified abrasives.
