What is the difference between aluminiun oxide and iron oxide?
One is oxidized aluminum and the other is oxidized iron. Iron oxide is magnetic. Aluminum oxide is not. Most of the clear semi precious gems like rubies and emeralds are made from aluminum oxide. Iron oxide is in hematite the black, opaque mineral.
What is name of the compound Al2O3?
Al is the symbol for Aluminum and O is the symbol for oxygen. When oxygen is paired in a compound, it is changed to oxide. The name then is aluminum oxide.
Is aluminum oxide metallic?
No, aluminum oxide is not metallic. But aluminum is.

The definition of aluminum oxide is various forms of aluminum oxide. This only occurred naturally as corundum.
What compound is this Al3O2?
Al2O3 is aluminum oxide, which is also called aluminium(III) oxide, alumina, aloxide, aloxite, or alundum. It occurs naturally as the mineral corundum.
What is sapphire's mineral name?
A variety of corundum, an aluminum oxide. Al2O3
What is chemical formula for Aluminum oxide?
That's about as scientific as it gets. The compound is also called "alumina", but that's not really its "scientific name".
Ruby a mineral or a rock?
Rubies (and sapphires also) are compounds of a crystallized mineral called corundum that consists mostly of aluminum oxide (Al2O3).
What is the simplest gem in regard to its chemical composition?
Diamond is pure carbon Also, Sapphire is Aluminum Oxide. (Analogous to how Iron Oxide is rust!)
