Abstract:

Using transonic continuum flow filament reactors adapted for use with dissociated fluorine the authors have successfully studied the high temperature heterogeneous kinetics of a number of important prototype fluorinemetal, semi-metal and insulator gasification reactions, with emphasis on Mo, W, Ir, Pt, B, C and Al2O3. The kinetic studies have combined for the first time a comparison of atomic and parent diatomic reactants, b reactant pressures and gassolid temperatures of practical interest, and c the absence of external transport limitations. In addition, the authors have developed necessary and useful byproduct information in the areas of i fast-response resistance-time data acquisition for reacting metals, ii F-atom production and detection, and absolute concentration determination, iii interhalogen thermodynamics FCl bond energy, iv heterogeneous F-atom loss processes, and v F2metal vapor chemiluminescent reactions in the gas phase downstream of reacting filaments.
