摘要
以钨丝为工作电极研究了冰晶石基电解质熔盐中ＳｉＯ＿２的阴极还原行为。根据循环伏安法与计时电位法的测定结果，硅在阴极的沉积机理为包含前置均相化学反应的４电子可逆传递过程。
The cathodic reduction of SiO_2 in cryolite-based molten electrolytes was stud-ied using tungsten wires as working electrodes. The results of voltammetric and chronopo-tentiometric measurements showed that the cathodic deposition of silicon involves a prior ho-mogenous chemical reaction,followed by a four electron reduction step.
