Abstract
A method of making a gas generant formulation which contains a transition metal diammine dinitrate is provided wherein a transition metal nitrate is reacted with an ammonia source to form an aqueous slurry containing 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.
