High alumina brick is a very common refractory which means bricks of Al₂O₃ content varies 48-90%, is widely used in high temperature kilns and furnace. Due to different Al₂O₃ content and properties, andalusite brick, mullite brick, corudunm-mullite brick, corrision resistanct high alumina, spineal brick are all belonging to branchs of high alumina bricks.

Normally, high alumina brick can be as refractory lining in stove,furnace and kilns, such as anode baking furnace, hot blast stove, non-ferrous furnace for ferronickle making, lime furnace, rotary kiln and etc.
