FUSED ALUMINIUM OXIDE
[EIRI/DPR/0911] J.C.9534
INTRODUCTION
Aluminium containing compound have been used by man as far back as 5300 BC. Two principal types of ores gibbsite Al2O3 3H2O and boehmite Al2O3 3H2O are of primary interest in todays commercial process because they contain 40-60% Al2O3 . If these two minerals become depleted in the far future clay rich in alumina (30-40%) are available in great abundance all over the world.
Bauxite ore can be white gray or cream coloured. The ore being used commercially today have a wide range of chemistries, Aceptable composition include the following range.
Al2O3 3H2O, -35-60%, Sio2, Fl2o3, 5-40%
Tio2, -1-4% H2o -10-35% other 0-2.0%
Aluminium Oxide are among the most versatile in modern industry for this reasons aluminium oxide is used virtually every important industry.
The important and versatile use of Aluminium oxide makes the product more demandable.
Aluminas (Alumminium Oxide) used in virtually every important industry to name just a few aluminas are used to purify water to make to produce steel alloys for waterproofing textiles for coating caramics and for making abrasive, refactory materials, cosmetics and electronics equipments.
The purity Al2O3 enterning the electrolytic process determines the purity of aluminiesproduced. Commercial grade of Al2O3 contain 99-99.5%, Al2O3 plus such impurities as H2o (0.10%), Sio2, (0.005-0.01%) Fl2o3 )0.005-0.03%) Tio2 (0.005) Zno (0.01-03%) and traces of V2o3, Na2o, P2o5, Nio,Cuo, Cr2o3, K2o, Cap and others.
More refined hence more expensive aluminas are produced for electrolytic cell where 99.9%+ aluminum is desired. The refined aluminas however find greater use in the chemical and ceramic industries.
