How do you do a oxidation equation with aluminum oxide?

Answer 1

Aluminum oxide is on the surface of any aluminum metal, however you probably want more than that. There are three ways to produce the aluminum-oxide.

1. You can melt the aluminum in a furnace. There will be a thin film on top of the molten metal, that is the aluninum-oxide. You can skim this off with anything of a melting point higher than aluminum. This method leaves you with messy gobs of aluminum oxide mixed with small amounts of aluminum.

2. You can mix up a batch of thermite and light it. Aluminum oxide is a by-product of the reaction. However, this is very dangerous and I don't know how you could collect the aluminum-oxide(it is probably mixed with the iron).

3. (My favorite)You grind the aluminum into powder, probably with a bench grinder, and burn it! You get a container that won't burn and set the container with the aluminum in it in a fire(big fire)! The aluminum will burn/oxidize and you are left with a container of aluminum-oxide!

Have fun be safe, oh and make some rubies while you're at it!!!

#4. use some red devel drain cleaner (* 99% Lye *) and mix in a small cup of hot water than place an aluminum bar into it.. it will produce ALLOT of heat, as the reaction is endothermic, as well as lots of hydrogen and FOAM. use a little WD40 in the water to reduce foam.. after the reaction has finished, the aluminum will be converted to Aluminum OXIDE and lye.

allow the mix of water/lye/aluminum oxide to evaporate in a tin. then add a little cutting oil to turn it into a paste.

when adding oil to lye, it turns it into SOAP.. so you'll end up with a polishing compound that will also cleaning agent.. be carefull LYE will cause burns from both the chemical and heat produced while the aluminum is converted to aluminum oxide. so use protective gear, face shield, gloves, and aprin.

enjoy.

Answer 2

Alumin(i)um Oxide Al2O3 is first of all dissolved in molten cryolite Na3AlF6 with calcium fluoride CaF2 and then electrolytically reduced to alumin(i)um at a temperature of approximately 965 °C .

An alternative process which converts the oxide to the carbide is in the process of being developed.

Answer 3

scrub it with bakeing soda, then use a metal polish on it,

Answer 4

This would be done by just heating it. Has to be hot enough to decompose though.

Example

Sn(OH)2 + Heat --> SnO + H2O

Answer 5

Aluminium oxide can be obtained by the calcination of aluminium hydroxide.

Answer 6

The reduction reaction is with aluminium and a typical example is:
Fe2O3 + 2 Al = 2 Fe + Al2O3
