Abstract
The electrodeposition of tungsten and voltammetric experiments were performed in basic ZnCl2NaClZnCl2NaCl (40-60 mol %) melts containing various tungsten compounds at 450°C. In constant potential electrolysis, metallic tungsten was obtained from WO3,WO3, K2WO4,K2WO4, WCl4,WCl4, and K2WCl6,K2WCl6, but not from K3W2Cl9K3W2Cl9 and WCl2.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. © 2000 The Electrochemical Society. All rights reserved.Keywords
