摘要: 采用循環伏安法首次研究了LiF-NaF-K2TiF6-KBF4熔鹽體系中鈦離子和硼離子在鉑、鉬電極上電化學還原及電合成硼化鈦的陰極過程機理。對恒電位電解的沉積物進行了X射線衍射分析。結果表明,當體系中硼鈦摩爾比B/Ti大于2時,鈦與硼可在同一電位下實現電解共沉積并反應生成硼化鈦。Abstract: The mechanism of the electrochemical reduction of Ti(Ⅳ) and B(Ⅲ) as well as the electrochemical synthesis of TiB2 on platinum and molybdenum electrode in molten Li-NaF-K2TiF6-KBF4 system has been investigated for the first time by. Means of cyclic voltammetry. The electrodeposited coating has been analysed by X-ray diffraction. The results show that the electrolytic codeposition of titanium and boron with the formation of TiB2 can be achieved at molar ratios B/Ti>2.
