Abstract
An apparatus is described which is suitable to study fused chlorides by the polarographic technique. Dropping bismuth is used in a way analogous to dropping mercury. Polarographic waves are shown for 
, 
, and 
in a 
eutectic melt at 450°C. The method serves as an analytical tool at high temperatures, besides yielding physicochemical information such as diffusion coefficients by application of the Ilkovic equation.
