Abstract
In the work, using the methods of cyclic voltammetry and open-circuit chronopotentiometry, and galvanostatic and potentiostatic electrolysis, the processes of the joint electroreduction of molybdate (tungstate) ions with carbonate ions against the background of a melt of potassium chloride at 1023–1173 K are studied. The possibility of the joint electrolysis of molybdenum (tungsten) and carbon in a potassium-chloride melt and the implementation on their basis of the electrochemical synthesis of molybdenum and tungsten carbides in the form of nanodispersed, submicrodispersed, and microdispersed powders. Samples of molybdenum and tungsten carbides are synthesized and characterized by X-ray phase analysis, laser particle-size analysis, and scanning electron microscopy.
该研究采用循环伏安法、开路计时电位法、静电电解法和静电电位法，研究了在 1023-1173 K 的氯化钾熔体背景下钼酸根（钨酸盐）离子与碳酸根离子的联合电还原过程。在氯化钾熔体中联合电解钼（钨）和碳的可能性，以及在此基础上以纳米分散、亚微分散和微分散粉末形式电化学合成钼和碳化钨的实施情况。合成的钼和碳化钨样品通过 X 射线相分析、激光粒度分析和扫描电子显微镜进行表征。
