1. A process for preparing a gas generating composition for a vehicle occupant protection apparatus comprising the following steps:

  • obtaining desired quantities of ingredients of the gas generating composition measured in predetermined amounts according to the percentage of the ingredients in the gas generating composition, the ingredients including an elastomeric binder, a fuel, and an oxidizer;

    mixing the ingredients with an azeotrope to form a suspension;

    atomizing the suspension to form a stream of spheroid droplets; and

    contacting the spheroid droplets with gas to remove the azeotrope from said spray droplets and produce solid spheroid particles of the gas generating composition in which the oxidizer and fuel particles are intimately mixed with each other and bound together by the elastomeric binder.
