A double-reduction process for producing Zr and Hf is described. The ZrCl/sub 4/ vapor is passed over a stirred bed of NaCl, ZrCl/sub 2/, ZrCl/sub 3/, and Na at 325 to 400 C. The product of this reaction, essentially NaCl and ZrCl/sub 2/, is again reduced with Na to produce sponge. For Hf the first reduction is with Na at 200 C, and the second reduction with Na at 960 for 4 hr. (T.R.H.)
