✦ Synopsis

Akstraet-The impurities expected to be present in alkali cyanide melts are discussed, and methods for their removal from a (K, Na)CN eutectic melt are then suggested. It was found that room-temperature vacuum-drying, combined with melting of the salt in the presence of silicon powder, gives the best results. The purity of melts is evaluated by iufrared spectroscopy on quenched melt samples.

Oscillographic polarography has been used to determine the diffusion coefficient of silver ion over a wide composition range of NaNO,-KNO, at 315, 340 and 360°C. Agreement of the polarographic diffusion coefficient with the chronopotentiometric diiusion coefficient has been found. The Ag+ diffusion
