Aluminium Oxide ( what can I do with it)

gardul - 2-2-2015 at 09:12

Good morning everyone.

Due to my recent studies; and many many failed experiments in making a stable aluminum chlorohydrate. I now have 143.40g of aluminium oxide. I need some suggestions in what I can do with it?

Catalyst or catalyst substrates, chromatography, filler, refractory, abrasive, ceramics...

Or make some Aluminum metal electrolytically.

You could make some TLC plates from microscope slides if you need them. This link uses silica, but alumina can be substituted without issue.

LOL! Slightly outside the capacity envelope of most hobbyists, I feel...

There is in fact a chemical method of preparing Al (and I'm not talking Wohler's method). Can anyone guess?

Threadjacking, sorry!

I believe the trichloride can be reduced by a Hg amalgam of Na or K.

That works but I think he's referring to the electrolysis of anhydrous AlCl3 in an alcoholic solvent and producing an amalgam. This method works with the rare earths according to Brauer.

[edit] oh, chemical method.

Reduction of AlF<sub>3</sub> with Mg in a thermite-style reaction is very exothermic. Working on it.

I may have to try that.

thanks everyone for the ideas.. I can't believe i types chloro chloro. Perhaps it's the chemist version of toro toro?
