Product Specifications
Various specifications of sand and powder
Scope of application
Bauxite is mainly used in welding rods, flux, aluminum smelting industry, precision casting, refractory products, aluminum silicate refractory fiber, bauxite cement, etc.
Products Description
Bauxite (aluminous soil; bauxite), also known as bauxite or bauxite, is divided into raw bauxite and cooked bauxite. It can also be divided into converter bauxite, vertical kiln bauxite, and inverted flame kiln bauxite. According to the particles, it can be divided into two types: aggregate and powder. The main component is alumina, which is hydrated alumina containing impurities and is an earthy mineral. White or off-white, brown or light red due to iron content. Density 3.9~4g/cm3, hardness 1~3, opaque and brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid and sodium hydroxide solutions.
Mainly used for aluminum smelting and high-grade refractory materials .
