Our high alumina brick is manufactured with selected bauxite chamotte as main material, fired at high temperature by advanced process with strict quality control. High alumina, as the name tells, meaning the content of alumina percentage is higher than
45. And alumina is one of the most chemically stable oxides, it offers excellent hardness, strength and spalling resistance. Our high alumina brick is widely used in industries which need heat insulation, such as the linings of masonry furnaces, hearth and shaft of blast furnaces, ceramic kilns, glass tanks, cement rotary kilns and so on.
