Bauxite as Refractory raw materials

 

Bauxite is a mixture of minerals that contain various concentrations of hydrated aluminum oxides as well as 

impurities, which is also called calcined bauxite or sintered bauxite. Its main component is alumina, which is a hydrated alumina containing impurities and is a kind of earthy mineral. White or off-white, brown or light red due to iron. Density 2.6 g/cm3, hardness 1-3, opaque, crisp. Extremely hard to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. It is mainly used for aluminum smelting and refractories.

 

Characteristics of Bauxite:
1. High refractoriness.
2. Physicochemical stability.
3. Volume density high .
4. Low porosity.
5. Low water absorption.
6. Fully calcined
7. Low impurity content.
