Abstract:The thermal behavior and properties of metal cluster compounds (n-Bu)4N]3WS4Ag3X3Br](X=Cl,Br,I) in a dynamic nitrogen atmosphere were studied by simultaneous TG-DTG-DTA technique. The probably expelled compositions in all the reaction stages were determined with help of elemental analysis for the intermediates during the processes; their thermal behaviors, meanwhile, were discussed in light of the chemical structure themselves. The thermal decomposition kinetics was investigated and the complexities of these processes were estimated based on the dependence of activation energy on extent of reaction.
Keywords:silver  tungsten  sulfur-containing metallic cluster    thermal analysis  thermal analysis kinetics
