The paper provides a review of industrial technologies for the production of nuclear zirconium. Their advantages and disadvantages have been shown, a comparative analysis of the quality of zirconium and hafnium salts has been given. Zirconium with a purity of 99.95%, is on a par with the quality of the iodide metal, with a hafnium content of less than 0.005%, was obtained from zirconium tetrafluoride (TFZ) by electrolysis and method of salt recovery with calcium.
