Abstract : Heat capacity and electrical resistivity of a carbon--carbon composite has been measured in the range of 1500 to 3000 K. The melting point of palladium has been measured. Apparatuses for the measurement of thermal expansion and thermal diffusitivity are described. The enthalpy of pure silicon carbide has been measured in the range of 273 to 1200 K. A discussion of the experiments leading to the electronic ground state of FeO is provided. The vibrational spectrum of Boron trimethyl is provided with the thermodynamic implications. (Author)
