High alumina refractories(bricks) are made from bauxite, a naturally occurring material containing aluminum hydroxide and kaolinitic clays. These raw materials are roasted to produce a mixture of synthetic alumina and mullite (an aluminosilicate mineral with the chemical formula 3Al2O3 · 2SiO2).


High alumina refractories can be divided into two kinds: shaped refractories and unshaped refractories. The main shaped refractories are high alumina bricks and the unshaped refractories are mainly high alumina castable.
Application: These high alumina refractories are mainly used in vertical kiln, rotary kiln, cement kiln, steel plant, power plant, EAF(Electric Arc Furnace) fertilizer plant and chemical plant.
