The chemical attraction of oxygen to aluminum is greater than that to carbon, so Al oxide 'wins' from C oxide to be formed or stay intact.

Reaction: 2 Al2O3 + 3 C --> 4 Al + 3 CO2 does NOT run to the right, as Fe2O3 does alright.

Aluminum oxide is a very stable compound, and it requires a lot of energy to break the strong bonds between aluminum and oxygen atoms. Coke does not provide enough reducing power to break these bonds and convert the aluminum oxide into aluminum metal. As a result, reduction of aluminum oxide with coke is not a practical method for obtaining aluminum metal.

aluminium oxide is ionic in nature. it forms a very strong bond .aluminium is stronger than coke and has stronger affinity on oxygen than on coke.

Aluminum is higher on the reactivity series than carbon, and so carbon cannot replace it in a compound as it can with iron.

What is the ore from which aluminium oxide is obtained?

Aluminium oxide is typically obtained from bauxite ore through the Bayer process. Bauxite is a sedimentary rock that contains high amounts of aluminium hydroxide minerals, which are processed to extract aluminium oxide, also known as alumina.


When bauxite is mined and purified what compound is obtained?

I think it is called Aluminium Oxide and the formula for it is Al2O3


What is the word equation for heating aluminium powder with iron oxide?
