| Outline of Final Research Achievements |
The HGP at ISEI reproduced core mantle boundary (CMB) condition in the SD-KMA for experiments. The SD-KMA is superior to DACs for quantitative studies because of its much larger (~1,000 ×) cell volume. Some studies, such as grain growth, diffusion, and phase relationships, can only be conducted reliably and with reproducibility in the SD-KMA. Another imporatant contribution is to measure thermal conductivity of pyroxenes under high temperature and high pressures.The other aspect of this project is the study of the elasticity of MgSiO3 perovskite and Post-perovskite.
