SOLID STATE ROUTES TO CRYSTALLINE GROUP IIB CHALCOGENIDES. APPLICATIONS OF METATHESIS REACTIONS

Thermolysis (500°C) of mixtures of MC1 2 (M = Zn, Cd, Hg) and Li 2 E (E = O, S, Se, Te) produces ME via an exothermic reaction.The ME compounds were characterised by microanalysis, scanning electron microscopy (SEM)/energy dispersive X-ray analysis (EDXA), FTIR and X-ray powder diffraction.Mixed metal-sulphides, M x M' y S and metal sulphide-selenides, MS x Se y were made by reaction of ground powders of MC1 2 , ΜΌ2 and L12S or Li2(So.5Seo.5).Recent interest has centered on the development of systematic routes to new and existing advanced materials with controls on substance morphology, stoichiometry, Volume I7, No. 8, 1994 Solid State Routes to Crystalline Group IIB Chalcogenides.Applications of Metathesis Reactions
