High pressure was generated with sintered diamond anvils inserted in the pressure medium of a multistage apparatus. X-ray diffraction using strong synchrotron radiation was sucessfully attempted. The X-ray transparency of the sintered diamond was unexpectedly high, and pressure of 60GPa was generated with the anvils of 0.7mm top face. Development of the technique of simultaneous measurement of electric resistance and lattice parameter under pressures up to 50GPa enabled the determination of the α→ε transition pressures of Fe-V alloys, which are useful as the pressure-fixed points in the ultrahigh pressure region.
