Abstract

AbstractThe melt of potassium thiocyanate can be used as solvent and as supplier of sulphur for the preparation of crystals of sulphides and complex sulphosalts. The solubilities of some sulphides in the KSCN melt were determined at 250°C. Small crystals of sulphides of Cu, Ag, Tl, Hg, Pb, Ni and of ternary As‐ and Sb‐sulphosalts of these metals could be obtained from this flux in a temperature gradient. Moreover, crystals of sulphides were formed by a direct slow reaction of metals with molten KSCN.
