Electrode and electrolyte for use in preparation of nitrogen trifluoride gas, and preparation method of nitrogen trifluoride gas by use of them |
摘要 |
An electrode for electrolyzing an electrolyte comprising an ammonium fluoride (NH4F)-hydrogen fluoride (HF)-containing molten salt and having a composition ratio (HF/NH4F) of 1 to 3 to prepare a nitrogen trifluoride (NF3) gas and an electrolyte for use in the preparation of NF3 gas, and a preparation method of the NF3 gas by the use of the electrode and the electrolyte. The electrode comprises nickel having 0.07 wt % or less of Si content and containing a transition metal other than nickel. The electrolyte also contains a transition metal other than nickel.
