Dense corundum is the best refractory raw material in the corundum series. 

Dense corundum is a kind of high grade refractory material. The main phase is α-Al2O3, grey-white color. 

Characteristic  :   High melting point, High Bulk Density, Low porosity 

   Properties     :   Good wear-resistance, good slag resistance, good bulk              stability, good thermal shock resistance. 

         Usage     :   Dense corundum is the ideal raw material to make blast furnace     iron  groove castable, ladle castable, ramming mass, precast     shapes,  monolithic refractories and functional refractories for CC      purging plugs, nozzle pocket brick and so on.

Dense corundum is widely used to steel, cement, ceramic and petrifaction industry.
