Description
The elastic properties of methane-propane mixed gas hydrate with cubic clathrate structure II (MPH-sII)have been determined as a function of pressure by high-pressure Brillouin spectroscopy up to 1.30 GPa at 296 K. The pressure dependences of the obtained elastic constants C_<11> and C_<44> of MPH-sII are obviously different from those of pure methane hydrate with cubic clathrate structure I (MH-sI), and indicate that the crystal of MPH-sII is elastically soft and weak against the shear stress in comparison with that of MH-sI. Those results suggest that the elastic properties and structural stability of gas hydrates depend on not only the guest molecule but also the gas hydrate structures.
