We synthesized methane hydrate using fine grain ice. The amount of released-gas volume was the same as calculated one for ideal methane hydrate within experimental precision. The neutron diffraction measurement was conducted by means of a high-resolution powder diffractometer (HRPD) installed at JRR-3. No reflection line from the impurities and ice was found in the diffraction pattern. Therefore, the synthesized methane hydrate proved to be very high quality. We also showed the scattering density map of this sample using Rietveld analysis and the maximum entropy method (MEM).
