This research was divided into four interrelated parts. It was an outgrowth of an investigation on the corrosion of nickel in SO2Ar and in SO2SO3Ar gas mixtures at 800 C. From the earlier studies it became clear that the transport properties of the sulfide, the oxidation of the sulfide itself and the transport properties of the duplex scale wre needed data. In addition, the thermodynamics of the sulfides were needed. Accordingly the following research was performed 1. Transport Properties of Ni3 or - xS2 a electrical conductivity b chemnical diffusilvity c radio tracer sulfur diffusion 2. Gibbs Free Energy of Ni3 or - xS2 and Fe1-xS by Galvanci Cells 3. Oxidation of Ni3 or - xS2 in oxygen at 700 C 4. Transport in NiO-Ni3S2 composites. In what follows, a brief summary of each researdch objective is presented followed by the publications and extended abstracts which contain the details. Originator supplied keywords include Electrical conductivity, Galvanci Cells, Composites, Thermodynamics, Sulfides.
