Abstract : The effects of doping on the chemical reactivity of beryllium and LMH-2 with respect to combustion was studied by means of differential thermal analysis (DTA). Specifically, the effects on doping with impurities on combustion was explored to determine if it is possible to increase the ignitibility of the fuels of interest. It was found that when beryllium and LMH-2 were heated under conditions of linearly increasing temperature from room temperature to 800 C in dry oxygen ignition did not take place. Under the same experimental conditions ignition occurred when the materials were doped with various metal fluorides or fluoro-silicates. The ignition temperature varied depending on the dopant impurity used. When an oxygen atmosphere saturated with water vapor in place of dry gas was used the reactivity of both fuels increased markedly. The exothermal decomposition of ammonium perchlorate was also observed to be catalyzed by some fluoride additives. Mixtures composed of the doped and undoped fuels and ammonium perchlorate were also investigated. (Author)
