Global Bauxite Market Report and Forecast
Bauxite is a silt rock, that has a high aluminium content. It is the main source of aluminium in the world. Primarily, bauxite consists of minerals like gibbsite, hematite, boehmite, anatase, goethite, and ilmenite. It is generally found near the surface of the terrain; therefore, strip mining, a form of surface mining, is conducted.

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world''s main source of aluminium and consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γAlO(OH)) and diaspore (αAlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH) 4) and small ...
Alumina Powder Al2O3 Maxwell Global Exports
Al2O3 + 3 H2O. The formed Al2O3 from bauxite is alumina. The alumina formed tends to be multiphase;, constituting several of the alumina phases rather than solely corundum. The production process can therefore be optimized to produce a tailored product.

News About the performance of high alumina bricks
The starting deformation temperature of highalumina bricks under load is greater than 1400℃, and it increases with the increase of Al₂O₃ content. For products with Al₂O₃ content less than %, the load softening temperature depends on the quantity ratio of mullite and glass phase, and it increases as the quantity of mullite increases.
