Why don't use aluminum chloride in the industrial production of aluminum element

[Thomas Miller]

A question from my brother.
He felt that aluminium chloride had a lower melting point and was more conducive to electrolysis.

[ChenBeier]

Commercial reason.

Bauxit aluminiumoxide will be produced by mining. This will be molten with an additive of Kryolith Na₃AlF₆.

Aluminiumchloride is not available it has to be produced first. And electrolysis will create chlorine

How volatile is AlCl₃ at elevated temperatures, and would this volatility pose an economic or safety risk during electrolysis?

[ChenBeier]

I wrote already. It creates chlorine gas during electrolysis.

[Thomas Miller]

Thank you for your answers. I asked my teacher, and he said that aluminum chloride is a covalent crystal rather than an ionic crystal, and it cannot ionize ions when melted, so it cannot be electrolyzed to obtain aluminum element.

Then show this to your teacher
