| Outline of Final Research Achievements |
Novel high-pressure and high-temperature techniques have been developed using tungsten carbide (WC), sintered diamond (SD), and nano-polycrystalline diamond (NPD) as ultra-hard anvils for some static high-pressure devices. The pressure and temperature ranges have been significantly expanded by these techniques, which have been applied to various studies such as using deformation, X-ray absorption, neutron diffraction, electrical conductivity, and sound velocity measurements under ultra-high pressure. Some important scientific results relevant to the mantle-core interaction have been obtained in collaboration with the researchers in other groups using thus developed techniques.
