Class Objectives
/Class Outline |
This course aims to provide an understanding of the principles and historical development of static high-temperature and high-pressure generation techniques. Students will learn about the research history of phase transitions in mantle materials and subducting slab materials investigated using these techniques, as well as the resulting insights into the composition and structure of Earth’s interior. In addition, the course will explore the forefront of novel materials development utilizing ultrahigh-pressure conditions. |
| Class Schedule |
1. Principles and historical development of ultrahigh-pressure techniques
2. Phase transitions of the mantle and plate-related materials
3. Development of in situ synchrotron X-ray observations
4. Density and elastic wave velocities of the mantle and plate materials
5. Chemical composition of the Earth’s mantle
6. Nano-polycrystalline diamond
7. Transparent nano-ceramics
8. Seminar: Creation of Ultrahigh-pressure materials science |
