Abstract
A method of making a gas generant formulation which contains a transition metal diammine dinitrate is provided wherein a transition metal ammine carbonate is reacted with nitric acid in the presence of water to form a corresponding reaction mixture. A spray dryable precursor to the gas generant formulation is formed including at least a gas generating fuel and a sufficient quantity of water to render the precursor spray dryable. The precursor is subsequently spray dried to form a gas generant powder. The method may also include a relatively mild heat treatment of the dried material, either as a part of the spray drying or subsequent to such spray drying. A phase stabilized ammonium nitrate and a corresponding method of making the same wherein ammonium nitrate is stabilized through the presence of a stabilizing metal diammine dinitrate are also provided.
