Kinetics of Halogen Gas/Solid Reactions at Elevated Temperatures.

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 fluorine/metal, 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 gas/solid 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) F2/metal vapor chemiluminescent reactions in the gas phase (downstream of reacting filaments).
