Bauxite, the main component is alumina, hydrated alumina containing impurities, is a kind of clay mineral. White or grayish white, brownish yellow or light red. Density 3.45g/cm3, hardness 1~3, opaque, brittle. Extremely difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used in aluminum smelting, refractory materials.
Size: 0-1mm,1-3mm,3-5mm,200mesh,325mesh,or as buyer's request.
2.Precision casting/Investment casting: bauxite grog fines can be made into mold for precision casting.
3.Refractory: high alumina bauxite's refractoriness can reach 1780°C.It is charactered by good chemical stability and mechanical performance.(Al2O3 ≥48% with low Fe2O3)
4.Aluminum silicate refractory fiber: The high alumina bauxite grog can melt under2000°C-2200°C in the electric arc furnace. After a series of processing, it can become aluminum silicate refractory fiber, which can be made into fiber blanket,plate,cloth.
5.Mixing magnesia and bauxite grog with binders to pour the molten steel ladle for better overall lining performance.
6.Producing bauxite cement.
9.Chemistry industry for all kinds of aluminum compound.
