Ternary Sulphide Phase Systems

The NagS-AsgSg system has been studied by thermal, JT-ray, and chemical analyses, at temperatures less than 870 °C. D.t.a. curves were obtained and compared for Na2S, AsgSa, NaAsSg, NagAsSj, and 1 1,2 1, and 3 1 mixtures

The superconductivity and structure of some ternary molybdenum sulphides 258 the non-stoicheiometry of ZrS2 259 and the phase systems ZnCd-S, ZnHg-S, and CdHg-S260 have all been investigated. The reaction of carbon disulphide with the metals of the transition groups IV, V, and VI, has been studied.261 In most cases, the product of the reaction at 800—1000 °C is a sulphide (or more rarely a mixture of two sulphides), but in the case of the metals niobium and tantalum a mixture of carbides is produced.
