摘要： It is a task of the present invention to provide an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt, the electrolytic apparatus being advantageous in that the electrolysis can be performed without the occurrence of the anode effect even at a high current density and without the occurrence of an anodic dissolution. In the present invention, this task has been accomplished by an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt at an applied current density of from 1 to 1,000 A/dm2, the electrolytic apparatus using a conductive diamond-coated electrode as an anode.

摘要： It is an object of the present invention to produce a carbon electrode having a texture with decreased pores and having relatively high mechanical strength by only being subjected to a process where a specified metal fluoride is mixed with a carbon material, then the mixture is baked, and to provide a carbon electrode for producing gaseous nitrogen trifluoride having a long life without the polarization of the carbon electrode even in any case of an NH4F—KF—HF series and an NH4F—HF series. The carbon electrode for producing gaseous nitrogen trifluoride of the present invention has a dense texture with an average pore size of 0.5 μm or less. It is preferable that the carbon electrode contains a carbonaceous material, and at least one of more kinds selected from magnesium fluoride and aluminum fluoride which have a melting point not lower than the baking temperature of the carbonaceous material. Also, it is preferable that the content of at least one of more kinds selected from the magnesium fluoride and the aluminum fluoride is 3 to 10 wt %.
