Abstract：

A　new　electrochemical　method　for　efficient　and　green　recovery　of　cemented　carbide　in　a　molten　salt　is　described.　Tungsten　powder　is　the　main　product　when　recovering　cemented　carbide　by　molten　salt　electrolysis.　However,　the　main　purpose　of　tungsten　powder　is　to　make　tungsten　carbide.　Based　on　this,　a　new　method　for　preparing　tungsten　carbide　by　in　situ　reduction　was　developed.　Pure　tungsten　carbide　powder　was　successfully　prepared　in　situ　by　pulse　electrolysis　in　a　NaF-KF　molten　salt　system　at　1073　K.　This　not　only　effectively　recovers　the　spent　cemented　carbide,　but　also　enriches　the　product　system　and　optimizes　the　method　for　preparation　of　tungsten　carbide　powder.
