Abstract
A method of making a ferric oxide burning rate catalyst that results in a highly active, finely divided burning rate enhancing catalyst. An iron-containing compound that is capable of vaporization at a temperature below about 500.degree. C. is vaporized. A mixture comprising the vaporized iron-containing compound is combusted with a gas that is capable of supporting combustion in an oxygen environment and does not condense below about 100.degree. C. The ferric oxide burning rate catalyst made by this process is particulary adapted for use in a composite solid rocket propellant. This process provides an ultra pure, highly active, finely divided burning rate catalyst.
