Abstract
The nickel-nickel oxide [ Ni NiO 1 + x ( 0 ≦ x < 0.5 ) ] composites prepared from a mixture of Ni and LiNiO 2 or NiO powders at 900°C under 2000 atm for 2 h by hot isostatic pressing were employed as the anode for electrolytic production of NF 3 . In electrolysis of a molten NH 4 F ⋅ 2 HF with and without LiF at 100°C and at 25 mA/cm2, the anode gas generated at the Ni NiO 1 + x composite anode was composed of N 2 , O 2 , NF 3 , N 2 F 2 , N 2 F 4 , and N 2 O , and its composition was almost the same as that at the Ni sheet anode. The current efficiency for ...Keywords
