Calcium electrolysis with alternative salts


Shouldn't it be easy (in theory) to find a Calcium salt with a low melting point (CaH2PO4 melts at 109°C) and perform an ordinary electrolysis to obtain Calcium? Calcium is said to be hard to make by an amateur

I would think using an acid phosphate the hydrogen would be released first.

Using a eutectic with salts that can not be reduced easily, from memory the eutectic can contain sodium or potassium. I think there is a thread about it.

Sorry I could not find the thread.

Damn I wish I could find this thread. Do you remember any details, like what the anions could have been?

I had an other search and found the following but I don't think its the one I was thinking about.

We successfully made a small amount of calcium metal by electrolysis of a barium chloride, calcium chloride, strontium chloride and potassium chloride (http://www.google.com/patents/US3226311). Addition of the other chlorides lowers the melting point of the mixture to around 600 C (and calcium is pretty much the product). We were wondering if barium could be made in a similar way.

Does anyone know anything about this?

Search for "Calcium electrolysis" there are a few more
