Introduction of calcined bauxite :

Raw Bauxite is the primary source of aluminium metal.The Clinker are pale yellow and dark gray, it is mainly used for high aluminum refractory material, can also be used to make the fused corundum, bauxite cement, abrasives, aluminium compound, precision casting. Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 850℃ to 1600 ℃ ) this removes moisture thereby increasing the alumina content, compared to an alumina content of about 57%to 58%in raw bauxite, calcined bauxite has an

alumina content of 75%to 90%, the heating is carried out in rotary kilns.

Applications of calcined bauxite :

(1) aluminium industry. Used in national defense, aerospace, automotive, electronics, chemical industry, daily necessities, etc. 
(2) precision casting. Alumina clinker made after the mould precision casting processed into fine powder. Used in military industry, aerospace, communications, instrumentation, machinery and medical equipment department. 
(3) is used for refractory products. High bauxite clinker refractoriness is as high as 1780, chemical stability strong, and good physical properties. 
(4) aluminum silicate refractory fiber. With light weight, high temperature resistance, good thermal stability, low thermal conductivity, heat capacity is small and the advantages of resistance to mechanical shock. Used in iron and steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. 
[5] in magnesia and bauxite clinker as raw materials, add the appropriate binder, used for pouring ladle whole ladle lining has particularly good effects. 
[6] manufacture alumina cement, abrasive materials, ceramic industry and chemical industry can be aluminum of various compounds
