Abstract

A highly active, finely divided ferric oxide burning rate catalyst and method for making the same. The catalyst is made by vaporizing an iron-containing compound that is capable of vaporization at a temperature below about 500.degree. C., and is capable of forming ferric oxide when reacted with an oxygen-containing atmosphere at temperatures below about 500.degree. C. The iron-containing compound is then oxidized in an oxygen-containing atmosphere. The ferric oxide burning rate catalyst made by this process is particularly adapted for use in a composite solid rocket propellant. This process provides an ultra pure, highly active, finely divided burning rate catalyst.
