Thermally Stable Burning Rate Accelerators.

Abstract

A small particle size AP has been produced by freeze-drying, fluid energy milling, and solvent/nonsolvent precipitation techniques from a master batch of thermally stable AP. A thermal stability (1% wt. loss at 375 F) in excess of 175 hours has been demonstrated. The inter-relationships between AP stability, AP particle size, and catalyst type have been studied in propellant. Ferrocene-type compounds containing electron withdrawing groups and those that do not contain an alpha hydrogen atom exhibited improved thermal stability when compared with n-butylferrocene. Propellants containing ferrocene type catalysts, which are insoluble in the binder, have thermal stabilities that are better than those obtained with counterpart soluble catalysts. (Author)
