Abstract:

The fluorination rates of elementary boron, silican and carbon and of TiB2 have been determined over wide ranges of temperature and fluorine partial pressures. The thermal decomposition of solid CF has been shown by gas chromatographic and mass spectrometric techniques to yield a variety of perfluorocarbons with up to 16 carbon atoms. High temperature heat capacities have been measured and analytical expressions representing experimental data over wide ranges of temperature have been derived for several borides, carbides, nitrides and oxides.
