Abstract
Pressure distribution in an octahedral pressure medium (pyrophyllite) placed in a multianvil (eight-anvil) high-pressure apparatus was measured by applying phase transitions in the calibrated metal (bismuth). It has been shown that the pressure at the edge of the octahedral medium is about 14% lower than that at the centre, where the pressure is 25.2 kbar. Confirmation is presented, showing that the distribution is improved when the pressure generated in the medium is increased, and a reasonable uniform pressure distribution is found at the pressure of 77.0 kbar.Keywords
