説明
The anodic dissolution of vanadium from VC-type carbide was investigated in two kinds of electrolytes, KCl–NaCl–NaF–K2NaVF6(44–44–7–5 mol%) and KF–NaF–K2NaVF6(62–33–5 mol%), in the temperature range of 700–850°C and in the cell voltage range of 0.8–1.4 V. A high degree of vanadium extraction was made from the spongy vanadium monocarbide anode which was prepared carbothermically from a mixture of V2O5 and medium coal tar pitch. This anode did not disintegrate even at an extraction percentage of 98%. Anode current efficiency of 40–50% and a high degree of vanadium extraction were obtained under the electrolytic conditions of 1.0–1.2 V and 825°C in the KF–NaF–K2NaVF6 electrolyte and also 1.4 V and 725°C in the KCl–NaCl–NaF–K2NaVF6 electrolyte.
