Tungsten　carbide　was　utilized　as　anode　to　extract　tungsten　in　a　NaCl-KCl-Na2WO4　molten　salt,　and　the　electrochemical　dissolution　was　investigated.　Although　the　molten　salt　electrochemical　method　is　a　short　process　method　of　tungsten　extraction　from　tungsten　carbide　in　one　step,　the　dissolution　efficiency　and　current　efficiency　are　quite　low.　In　order　to　improve　the　dissolution　rate　and　current　efficiency,　the　sodium　tungstate　was　added　as　the　active　substance.　The　dissolution　rate,　the　anode　current　efficiency,　and　the　cathode　current　efficiency　were　calculated　with　different　contents　of　sodium　tungstate　addition.　The　anodes　prior　to　and　following　the　reaction,　as　well　as　the　product,　were　analyzed　through　X-ray　diffraction,　scanning　electron　microscopy,　and　energy　dispersive　spectrometry.　The　results　demonstrated　that　the　sodium　tungstate　could　improve　the　dissolution　rate　and　the　current　efficiency,　due　to　the　addition　of　sodium　tungstate　decreasing　the　charge　transfer　resistance　in　the　electrolysis　system.　Due　to　the　fact　that　the　addition　of　sodium　tungstate　could　remove　the　carbon　during　electrolysis,　pure　tungsten　powders　with　100　nm　diameter　were　obtained　when　the　content　of　sodium　tungstate　was　1.0　pct.
