Details information

 

 

 

Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron.From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.

 

 

Application:

 

1. Aluminium metallurgy
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. Aluminium silicate refractory fiber: The high alumina bauxite grog can melt under 2000°C-2200°C in the electric arc furnace.After a series of processing, it can become aluminium 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
7. Abrasives
8. Ceramics industry
9. Chemistry industry for all kinds of aluminium compound.
