This catalytic reaction proceeds according to the scheme 3N2H4 4NH3+N2. Ammonia corresponds to an equimolar amount of chemisorbed hydrazine (nN2H4(g) nNH3(g)+(NH)n(ads) ).. Keywords: Hydrazine, Germanium, Catalytic decomposition. INTRODUCTION Hydrazine is one of the most chemically active substances - a strong reducing agent. He has wide application in various fields of industry, technology, medicine, etc. and has been intensively studied both previously and currently [1-12]. Liquid N2H4 is very hygroscopicand has a noticeable ability to absorb oxygen and carbon dioxide from the air. It is called “high purity” when the water content does not exceed 1 wt.% and “ultra-pure” - with a maximum of 0.5 wt.% H2O. The concentration of water in hydrazine is estimated by the density, melting point, or refractive index of the mixture. However, literature data on these parameters are different, due to the difficulty of accurately determining the physical characteristics of pure hydrazine. (*) Hydrazine is easily decomposed by heat and radiation, especially in the presence of catalysts [13-17]. The general form of this reaction is given by the equation: 3N2H4 4(1-x)NH3+(1+2x)N2+6xH2.
