Bauxite with Cheap Price Originated in China Popular Foundry Products

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.  From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle.  Very difficult to melt.  Insoluble in water,  soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material. 

2.Main Features of the Calcined Bauxite

Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite contains hydrous aluminum oxides and aluminum

hydroxides, formed through the laterization of aluminous rocks in tropical and subtropical areas .Calcined bauxite is obtained by calcining (heating)superior grade bauxite at high temperature (from 85OC to 1600C) .This removes moisture there. By increasing the alumina content,compared to an alumina content of about 57%to 58% in raw bauxite, calcined bauxite has an alumina content of 84%to88%.The heating is carried out in rotary kilns. 

3.Main usage of the 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 compound.
