In this study, methane-hydrate is produced by the mixed gases of methane and xenon, and the productive conditions of methane-hydrate is clarified. Methane-hydrate is noticed as new energy in recent years. The molecule of methane enter the crystal of the molecule of water then methane-hydrate is formed. Methane-hydrate is crystal of solid like ice and stable at low temperature and high pressure. In normal temperature and normal pressure, methane-hydrate decompose and become gas and water. As purpose of use of methane-hydrate, a cold heat source, storage of a natural gas, etc. are considered.
