Abstract: The main subject of the present invention are solid compounds capable of generating hydrogen by a self-sustaining combustion reaction. Their composition comprises borazane and/or polyaminoborane and at least one inorganic oxidant, advantageously chosen from ammonium nitrate, alkali metal nitrates, alkaline-earth metal nitrates, metal nitrates, metal oxides, oxidants of the family of dinitramines and mixtures thereof. It also relates to the generation of hydrogen by self-sustaining combustion of at least one such compound.

Abstract: Compositions to generate nitrogenous gas, with a low decomposition temperature, and processes for the generation of nitrogenous gas comprising the decomposition of such compositions, are provided. The compositions include azodicarbonamide, a nitrogenous reducing charge, and at least one additive. The azodicarbonamide and the nitrogenous reducing charge represent at least 90% of their weight. The nitrogenous reducing charge includes at least one compound from a first family of reducing components chosen from tetrazole, tetrazole derivatives and their salts, salts of bitetrazole and of its derivatives, 5,5?-azobitetrazole salts, polyvinyltetrazoles and their mixtures; and/or at least one compound from a second family of reducing components chosen from dicyandiamide, 1-hydrobenzotriazole, silicon nitride, nitroguanidine, guanidine nitrate and their mixtures. a nitrogenous reducing charge and azodicarbonamide.

Abstract: A subject matter of the present invention is compositions which generate nitrogenous gas, with a low decomposition temperature, and processes for the generation of nitrogenous gas comprising the decomposition of such compositions. Said compositions comprise: from 20 to 80% by weight of azodicarbonamide, from 20 to 80% by weight of a nitrogenous reducing charge, from 0 to less than 10% by weight of at least one additive; said azodicarbonamide and said nitrogenous reducing charge representing at least 90% of their weight and said nitrogenous reducing charge comprising: at least one compound from a first family of reducing components chosen from tetrazole, tetrazole derivatives and their salts, salts of bitetrazole and of its derivatives, 5,5?-azobitetrazole salts, polyvinyltetrazoles and their mixtures; and/or at least one compound from a second family of reducing components chosen from dicyandiamide, 1-hydrobenzotriazole, silicon nitride, nitroguanidine, guanidine nitrate and their mixtures.

Abstract: The present invention provides pyrotechnic grains of composition comprising at least one oxidizing charge and at least one reducing charge and no binder. In characteristic manner, said grains are in the form of substantially cylindrical blocks: with a thickness of more than 5 mm; with an equivalent diameter of 10 mm or more; and with porosity in the range 1% to 8%, limits included. Said grains, advantageously based on guanidine nitrate and basic copper nitrate, are suitable for the slow, low-pressure generation of gas over an extended period.
