en: Development of a new Bridgman-type high-pressure cell by using built-in gasket up to 9.4 GPa and evaluation of deformation

en: We have developed a built-in gasket for the Bridgman-type opposed-anvil high-pressure cell, featuring a PTFE (Teflon) capsule of 2.0 (1.5) × 2.5 mm3, filled with a liquid pressure-transmitting medium. This gasket, comprising a stainless-steel plane disk, a stainless-steel support ring, and pyrophyllite support gaskets, has enhanced the sample space height, allowed for precise adjustment of the anvil top area, and facilitated easy electrical insulation of lead wires. We calibrated the pressure by detecting phase transitions in Bi and Sn through resistivity measurements, achieving nearly hydrostatic pressure up to 9.4 GPa with this cell. Our analysis of the deformation of the gasket components under force has provided guidelines for effective pressurization.
