| Outline of Final Research Achievements |
We have conducted the high-pressure Brillouin scattering and Raman scattering measurements on silicate glasses to extract the physical properties of silicate magmas such as its structure and thermal conductivity combined with synchrotron facility. Using newly developped measurement system for sound velocity and structural data, we succeeded to measure the sound velocity and Raman scattering data above 100 GPa, and the optical absorption data above 80 GPa.
The results demonstrated that the silicate glasses as the analog of silicate melts drastically densified above 100 GPa, and the radiative thermal conductivity significantly decreased with pressure.
