A process for obtaining a solid form containing heat-stabilized borazane is described. The solid form is capable of generating hydrogen by thermal decomposition or by a self-maintained combustion reaction. Within the solid form containing borazane, the borazane is heat-stabilized. It has thus been heat-stabilized by making an oxidized layer at its surface.

Obtaining a solid form containing heat-stabilized borazane, said solid form, and the use thereof for generating hydrogen

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.
