Temperature field analysis in tungsten-copper alloy powder preparation by molten salt electrolysis

Based on the research of preparing tungsten copper alloy powder from Na₂WO₄ and CuO by molten salt electrolysis method, the temperature field distribution of the electrolysis cell and the influence of the electrochemical behavior around temperature distribution nearby the electrode area are analyzed. Temperature is measured by the displacement method and the experimental error is analyzed. The results show that temperature field distribution and electric field distribution in the electrolytic cell interact with each other, and the electrode potential is affected by temperature conditions. In the meanwhile, the external electric field disturbs the temperature field in electrolysis cell to make the uneven distribution of temperature field around electrode area.
