Fused-salt systems reference electrodes

Reference Electrodes For Use in Fused-Salt Systems. The kinds of investigations that require reliable reference electrodes in molten salts duplicate those in aqueous electrolytes. Specifically, these include (1) thermodynamic... 

The literature on fused-salt systems is too vast to survey here, but good access to the literature is provided in two reviews.55,56 Both contain useful information on solvent systems and suitable reference electrodes.

When the electrolysis is carried out in molten salts at high temperatures, special, chemically highly resistant reference electrodes should be used. In most cases pseudo-reference electrodes or quasi-reference electrodes, such as a piece of metal (Mo, Al-Li alloy, etc.), are used (see Chap. 14). However, in many two-electrode systems one of the electrodes consists of a metal and its fused salt, e.g., Ag AgCl, Mg I MgCl2, Pb PbCl2, Tl TlCl, and Zn ZnCl2 or oxide, e.g., Al AI2O3 which makes the comparison of the electrode potentials possible (see Chap. 8).
