Filed: 1990-11-16
Abstract: PURPOSE:To prevent gaseous H2 from being mixed with gaseous NF3 and to safely produce the gaseous NF3 by forming the material of a cathode of Ni at the time of producing the gaseous NF3 by a fused salt electrolysis method. CONSTITUTION:The gaseous NF3 is produced by electrolyzing a fused salt of a KF-NH4F-HF system or the like in an electrolytic cell 1 by the fused salt electrolysis method and generating the gaseous NF3 and gaseous N2 from an anode 5 and the gaseous H2 from the cathode 6.
