Can you mix molten metal and molten salt?
« on: 12/10/2010 12:57:30 »
I was wondering if it is possible to mix molten metal and molten salt. I understand the difference in boiling points might play a role, but if one were to get it right what would the properties of the product be?

Tried to find it on the internet but couldn't.

No, you can't, because there are no attraction between molten metal atoms and molten salt ions/molecules, the kind of bonding in a metal and in a salt is completely different.

Cool, thanks. They make carbon steel, so i was wondering what happens if you try it with other stuff.

Metallic Aluminium is produced by passing an electric current thru a molten salt

Some metals will indeed dissolve to some extent in their molten salts (for example, metallic sodium in molten sodium chloride): https://pubs.acs.org/doi/pdf/10.1021/ja01607a016

Yes you can.
A metal ion in a metal surrounded by electrons and a metal ion in a molten salt surrounded by negative ions are quite similar.

Mercury is slightly soluble in water and in hexane , why wouldn't it dissolve in a molten salt?
