High alumina brick's raw materials are high bauxite grog, cyanite, andalusite and sillimanite, compound mullite and electro-cast aluminum oxide. It has a high quality of refractoriness, and a good corrosion resistance for acid and alkali slag. Its high temperature mechanical strength is really high. It includes the following types:

 Ordinary high alumina brick;

high refractoriness under load and low creep high alumina brick used in blast furnaces, hot blast stoves;

wear resistance and peeling off resistance high alumina brick in cement kiln;

slag resistance and good thermal stability high alumina brick used in steel metrological industry.
