摘　　要：The mechanisms of the electrochemical reduction and nucleation process of B（Ⅲ） on the platinum electrode in the LiF-NaF-KF-KBF4 molten salt at 700℃ were first investigated using cyclic voltammetry and chronoamperometry techniques. It was found that the electrochemical reduction of B（Ⅲ） occurs in single-step charge transfer： B（Ⅲ） ＋ 3e → B, and the cathode process is reversible. The electrocrystallization process of B（Ⅲ） is instantaneous.The mechanisms of the electrochemical reduction and nucleation process of B（Ⅲ） on the platinum electrode in the LiF-NaF-KF-KBF4 molten salt at 700℃ were first investigated using cyclic voltammetry and chronoamperometry techniques.
