A process for preparing a gas generating composition (62) for a vehicle occupant protection apparatus (110) comprises the following steps. Desired quantities of ingredients of the gas generating composition (62) measured in predetermined amounts according to the percentage of the ingredients in the gas generating composition (62) are obtained. The ingredients include an elastomeric binder (16), an oxidizer (12), and a fuel (14). The ingredients are mixed with an azeotrope (28) to form a suspension. The suspension is atomized to form a stream (48) of spheroid droplets. The spheroid droplets are contacted with a hot gas to remove the azeotrope (28) from the spray droplets and produce solid spheroid particles of the gas generating composition (62) in which the oxidizer and fuel particles are intimately mixed with each other and bound together by the elastomeric binder.
