ВЛИЯНИЕ KI НА КИНЕТИКУ КАТОДНОГО ПРОЦЕССА В РАСПЛАВЕ KF-KCL-K2SIF6 И МОРФОЛОГИЮ ОСАЖДАЕМОГО КРЕМНИЯ

Abstract

The process of electrochemical reduction of silicon on glassy carbon in the melt (mol %) 66.5KF–33.3KCl–0.23K2SiF6 was studied by linear voltammetry. The influence of the addition of 2 mol. % KI on the electroreduction of silicon was studied. The effect of the meniscus on the peak value of the cathode current density of the electrochemical reduction of silicon on glassy carbon is estimated. It has been found that the addition of potassium iodide to the melt under study has no effect on the kinetics and mechanism of the electrochemical reduction of silicon ions.
