  • Patent number: 4381206
    Abstract: Disclosed is an all amine borane gas generating system which consists of razine bis-borane or its deuterated derivative in the form of a compacted solid propellant pellet which serves as the thermal stimulus for the decomposition of itself. An all amine borane gas generating system which additionally consists of diborane diammoniate or its deuterated derivative provides a higher yield of hydrogen or deuterium with a higher purity from a self-sustaining reaction after the self-sustaining reaction is initiated by a heat source (e.g., an electrically heated nichrome wire) sufficient to initiate the reaction. This all amine borane gas generating system which consists of N.sub.2 H.sub.4.2BH.sub.3 and H.sub.2 B(NH.sub.3).sub.2 BH.sub.4 is in the form of a compacted solid propellant pellet. The pellets are formed to the desired configuration employing pressures from about 500 to about 10,000 pounds total load. The solid propellant pellets are useful as a H.sub.2 or D.sub.2 generation sources for fuels for lasers.
