Question

Metallothermic production of zirconium (Zr) would involve the reaction of sodium (Na) with zirconium tetrachloride (ZrCl4) to produce zirconium and NaCl.

Answer 1

Yes, that's reasonable. Titanium, which is just above zirconium, is made this way. Both Ti and Zr are very active metals, and only a still more active metal, such as sodium, can reduce them.
