Mg metal reax w/ metal salts


I'm looking for information on reacting magnesium turnings with metal salts. I did a search and didn't come up with anything I could use. I want to combine magnesium with another metal by way of the other metal's salt. This is outside my experience. I'd appreciate any info and especially on what is most likely to combine most readily with Mg.

Thanks.

Any specificity as to what metal you want to combine the magnesium metal with?

Halides are the best bet, any oxysalt like sulfates is likely to undergo reduction of the anion as well. Also the halides frequently have lower melting points that the oxysalts, and the magnesium halide will be in liquid form to unlike MgO.

Like the Goldschmidt process/thermite reaction, magnesium reductions tend to be energetic. The production of titanium and uranium are illustrative of the process, although calcium is more frequently used for uranium.
