Abstract

The use of two parallel thermochemical reactions, sulfidization and fluorination, to increase the sensitivity of the spectrographic determination of zirconium in molybdenum was investigated. To determine zirconium quantitatively in amounts of 1x10−4 or more the molybdenum is first converted to the trioxide, and the thermochemical reactions are then used to form volatile zirconium tetrafluoride which evaporates in the arc, leaving the nonvolatile molybdenum sulfide behind.
