  • A mathematical model for differential thermal analysis

    Creator:
    Kaakinen, J. W.
    Abstract:
    A mathematical model of a differential thermal analysis (DTA) system was formulated so that influence of the various physical parameters on the DTA peak could be determined. The specific DTA apparatus simulated had cylindrical sample holes drilled into a nickel block considered to have a negligible thermal resistance, and the...

  • Efficiency of thorium extraction by primary amines as a function of pulse frequency and amplitude in a pulsed sieve-plate column

    Creator:
    Davis, Bernard Eric, 1937-
    Abstract:
    The amine extraction process is evaluated for pulse column operation. A 0.1 M solution of Primene JM-T (a commercial mixture of tertiary-alkyl primary amines) in a kerosene-base diluent is the extractant for thorium feed in aqueous acidic sulfate solutions. Equilibrium isotherms at room temperature are presented at aqueous acidities of...

  • Kinetics of thermal decomposition of tungsten hexacarbonyl

    Creator:
    Knapp, Samuel Boyd
    Abstract:
    The thermal decomposition of tungsten hexacarbonyl was investigated in an apparatus which allowed a solid sample of the material to be sealed into a preheated batch reactor. Because the reaction occurs with an increase in the number of moles of gas, it was possible to monitor the progress of the...
