Abstract : The report summarizes a two year study of the combustion efficiency of single beryllium droplets burning in a variety of oxidizers, but primarily mixtures of oxygen/argon and oxygen/nitrogen. An advanced laser heating technique has been used to acquire systematic quantitative data on the burning of single beryllium droplets at atmospheric pressure. This research confirms the sensitivity of beryllium droplet combustion to the chemistry of environmental species and provides experimental documentation for the nitrogen-induced droplet fragmentation of burning beryllium droplets. These studies clearly reveal the inadequacies of current droplet burning models as applied to beryllium but they also provide the sort of detailed, systematic foundation necessary for future rational development of the theory.
