Bauxite

Bauxite is a common refractory material, mainly composed of alumina and silicate。 It has excellent fire resistance and high temperature resistance, chemical corrosion resistance, and good resistance to acids, alkalis, etc. Additionally, bauxite also has certain insulation properties. It plays an important role in many high-temperature, refractory, and chemical industries.

Product Application:

Refractory materials, used to produce various high alumina refractory products and unshaped refractory materials。 Bauxite as raw material produced refractory precision devices or refractory fibe. Used in Aluminum smelting industry, precision casting. The high alumina clinker used to produce refractory bricks for the lining of high-temperature kilns in industries such as smelting, chemical industry, and glass.

In addition, bauxite is also used to make ceramics, grinding materials, fireproof materials, insulation materials, etc.
