摘　　要：在熔盐电解法由Na2WO4和CuO制取钨铜合金粉体的研究基础上,分析电解槽内的温度场分布,特别是电极区域的温度分布情况对电解行为的影响.通过位移法测量,采取比较法分析实验误差,结果表明:电解过程中2个主要的外部条件,即电解槽内温场分布与电场分布是联动的;温度条件影响着电极电位;同时,外部槽电压通过电流扰动槽内温场,使电极区域温场分布不均.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.
