Product Description

Product Description

Bauxite is also called the alumina oxide,whose main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.
Calcined bauxite is one of the principal ore of aluminum. Calcined bauxite is obtained by calcining (heating) superior grade bauxite at high temperature (from 850ºC to 1600ºC). 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 84% to 88%.Besides, through calcination, the density and refractory resistance will also be improved to varying degrees. The grade of bauxite can be increased greatly.

Product Application

1,Calcined Bauxite for refractory material
Such calcination of bauxite has the properties of high alumina, low iron, high hardness, small thermal expansion coefficient, high refractoriness, and stable thermal chemical performance, so it is the main raw material of producing alumina and artificial corundum refractory materials.
2,Calcined Bauxite for precision casting
The alumina clinker which is processed into fine powder and made into cast mould can be used in military, aerospace, communications.
3,Calcined Bauxite for aluminum refining Industry
It can be used for national defense, aviation, automobiles, electrical appliances, chemicals, daily necessities.
4,Calcined Bauxite for high friction surface coating
Calcined bauxite has been the most commonly used aggregate material used for High Friction Surfacing. The inherent nature of Calcined Bauxite resists shear stresses that lead to polishing of the road surface. Always be used in anti-akid road surface.

Besides, calcined bauxite can be also used in making refractory bricks, castable, welding flux, etc.
