Outline of Final Research Achievements

Extension of a capability of pressure and temperature generation for belt type apparatus is beneficial for materials science. By using taper shape pressure amplifier on a top of anvils, experiments at 20GPa/room temperature and 12GP/1200℃ could be carried out. Effects of a size of cylinder core and parameter for the pressure amplifier were also studied. For the practical use, synthesis of wurtzite type boron nitride crystal for its optical characterization and stishovite crystals for muon-spin study were carried out by using the developed high pressure apparatus.
