Corundum Chrome Brick

Corundum Chrome Brick (KPA) is the premium version of Alumina Chrome Brick

Corundum Chrome Brick (KPA ) made primarily of high purity chrome corundum clinker, alumina and chrome oxides under high temperature burning, KPA has better properties in refractories, RUL, MOR, high temperature creep, volume stability and resistance to slag corrosion compared with pure corundum bricks. It can be used as enhanced High Purity Corundum Brick (HPA)

It has excellent acid resistance and high temperature resistance. Widely used in chemical industry, glass, waste incineration, non-ferrous metal smelting and other key parts of the industry.

Corundum Chrome Brick
Alumina Chrome Brick
consist of combinations of the two oxides fired to develop a solid-solution bond. A wide range of products are available depending upon Cr2O3 content. These include a 90% Al2O3-10% Cr2O3 product based on high purity sintered alumina and pure chromic oxide. The solid solution developed in firing results in brick with exceptional cold strength, hot strength and load-bearing ability. In addition, the solid-solution bond between alumina and chromic oxide is inert to a wide variety of slags. Brick with higher Cr2O3 contents is also available. Based on a special fused grain high in chromic oxide, these products are selected for the most extreme cases of high temperature and corrosiveness.
