Corundum series, which is made of fused cast white corundum, plate corundum and superfine powder, is sintered under high temperature. There are generally three moulding methods of it: pressure moulding, casting moulding and vibration moulding.
According to different contents of alumina, it can be divided into:
High purity corundum products;
Sintered corundum products:
Corundum mullite products;
It is mainly used in glass furnaces. Furthermore, it is able to be applied to key parts of furnaces in industries of steel, petrochemical, chemical fertilizer, non-ferrous metal, electronics, refractory materials, etc.
It has advantages of high temperature resistance, high compressive strength, high temperature erosion resistance and washing-out resistance. Especially, it has a good reputation of zero pollution for the parts contacting with liquid glass.
