초록

A technique is provided for making a granulated propellant suitable for gas generation for an automobile passenger restraint bag. The propellant is about ¼anhydrous nickel formate and ¾potassium chlorate. The dry powders are blended and mixed with about 12 to 15% of liquid comprising water and up to 50% methanol. The blended mixture is granulated and dehydrated.
