  3. 2. Thermal Conductivity of Uranium Mononitride

    Master-uppsats, Linköpings universitet/Tunnfilmsfysik

    Författare :Mikael Valter; [2015]
    Nyckelord :uranium nitride; porosity; thermal conductivity; laser flash analysis; nuclear fuel;

    Sammanfattning : Thermal conductivity is a crucial parameter for nuclear fuel, as it sets an upper limit on reactor operating temperature to have safety margins. Uranium mononitride (UN) is a prospective fuel for fast reactors, for which limited experimental studies have been conducted, compared to the currently dominating light-water reactor fuel, uranium dioxide.

  4. 3. Synthesis and characterization of nano-structured CoSb3 thermoelectric material

    Master-uppsats, KTH/Materialvetenskap

    Författare :Abdullah Khan; [2009]
    Nyckelord :Thermoelectric CoSb3; Intermetallics; Spark Plasma Sintering; MS Thesis;

    Sammanfattning : In this project, nano powder of CoSb3 thermoelectric material was synthesized using chemical alloying novel co-precipitation method. This method involved co-precipitation of TE precursor compounds in controlled pH aqueous solutions followed by thermo-chemical treatments including calcination and reduction to produce nano-particulates of CoSb3.
