Gas-phase metal reactions

The use of new advanced solid rocket propellant constituents, such as, e.g., boron as HEDM and ammonium nitrate as replacement for halogen-containing oxidants, requires knowledge of their combustion characteristics. To this end experimental rate coefficient k measurements on individual important Al and B species reactions were made in the 300-1800 K temperature range using a high- temperature fast-flow reactor. Temperature dependent rate coefficient expressions k(T) = AT(super n)exp( -E/RT) are found for the reactions between AlO and CH4, O2; Al and N2O: AlCl and N2O, CO2, SO 2; BCl and N2O, SO2; BO and CO2. To allow semi-empirical predictions for further metal oxidation reactions, two semi-empirical theories have been developed and utilized. These are Semi-Empirical Configuration Interaction theory for prediction of E from one species to another and metals-Transition State Theory for prediction of k(T) from k at one temperature. Dual military-civilian applications of this work are discussed. jg p. 1.
