Abstract
Reaction of elemental zinc, cadmium, or mercury with sulfur in liquid ammonia at room temperature produces X-ray amorphous metal sulfide MS (M = Zn, Cd, Hg). Thermolysis of this material at 250–300°C produced crystalline MS (α-ZnS (wurtzite), α-CdS (greenockite), α-HgS (cinnabar), and β-HgS (metacinnabar). Products were characterised by microanalysis, FT-IR and Raman spectroscopy, SEM/EDAX, X-ray powder diffraction, magnetic moment measurements, and X-ray photoelectron spectroscopy.
