摘要：

The electrodeposition of tungsten and Voltammetric experiments were performed in basic ZnCl2-NaCl (40-60 mol %) melts containing various tungsten compounds at 450 degreesC. In constant potential electrolysis, metallic tungsten was obtained from WO3, K2WO4, WCl4, and K2WCl6, but not from K3W2Cl9 and WCl2. Similar to the case of acidic melt (60-40 mol %), the oxide ion or an oxochlorotungsten species may participate in the electrodeposition process. The presence of molecular oxygen does not interfere with the process. (C) 2000 The Electrochemical Society. All rights reserved.
