Abstract : The primary objective of this program is the development of reactant particles which undergo chemical reaction at rates high enough to meet performance targets set in earlier programs for a high temperature chemical process for separation of air into oxygen and nitrogen. Such reactant particles must be able to retain their structure and reactivity under the separator operation conditions. Several approaches were taken towards the manufacture and testing of the desired reactant particles. The cyclic and noncyclic reaction rates of most of the reactant particles produced have been measured. The emphasis has been on rate determination in the 0.07 to 0.5 second time interval. The effects of raw material structure, particle processing conditions, and the use of support materials on ultimate particle reactivity have been studied. The effects of chemical additives on the reaction equilibria and kinetics of the reactant oxides have been investigated, and the effect of ionizing radiation on the reactivity of the oxide systems presently considered has been studied. The reaction rate data measured for the most reactive particles developed in this program have been used as the basis for separator system weight calculations for two different types of vehicles. The results of these separator system weight calculations are presented in Part 1 of Volume 3.
