This thesis work reports on the kinetics of methane hydrate formation from ice Ih powder at conditions of hydrate stability below the quadruple point in order to address open issues on gas hydrate growth. It was conducted in the framework of a DFG-project Ku 920/9 devoted to the study of ice surfaces and ice interfaces. In this work for the first time results of different experimental methods studying the gas hydrate growth were combined and checked for consistency. Valuable quantitative information of the methane hydrate formation was obtained by neutron diffraction and gas consumption measurements. Similar studies were also attempted on the hydrate growth using X-ray diffraction Sprache der Zusammenfassung: Englisch @Göttingen, Univ., Diss., 2004
