LiF—NaF—K2TiF6熔盐中Ti（Ⅳ）的电化学还原

用循环伏安法和卷积技术研究了ＬｉＦ－ＮａＦ低共熔体中，以Ｋ２ＴｉＦ６形式加入的Ｔｉ（Ⅳ）在铂电极上钥极还原机理，计算了各还原步骤所传递的电子数。结果表明：Ｔｉ（Ⅳ）的电化学还原机理为耦联均相歧化反应的三步骤电荷传递反应。

High-temperature Reference Electrodes Used in Molten Fluorides

The thermodynamic and dynamic behaviour of Ni~(2+)|Ni couple in FLINAK melt is investigated by us-ing EMF measurement and micropolarization method.The couple shows the Nernstian reversibility and alarge exchange current density(6 mA·cm~(-2)).A single crystal LaF_3 which is a fluoride ion conductor usedas a membrane of the Ni~(2+)|Ni couple reference electrode is reliable in FLINAK melts at 973 K.The poten-tial of LaF_3 membrane reference electrode is constant within±2 mV.The boron nitride used as a saltbridge was not good in FLINAK melts.The platinum electrode is studied by using micropolarization.Theequilibrium potential of Pt electrode is dependent on the absorption and the electrochemical reaction.Thepotential is stable for a constant composition at constant temperature.
