Overview

Experimental study demonstrates sustained 100,000 atmospheres and 2000°C using a belted chamber apparatus, suggesting new avenues for ultra-high-pressure high-temperature synthesis.

Key Points

To develop and evaluate a stable apparatus capable of maintaining extreme pressures and high temperatures simultaneously over prolonged experimental durations.
Engineered an apparatus featuring opposed conical Carboloy pistons that push into a contoured Carboloy chamber, reinforced laterally with prestressed binding rings.
Fabricated composite sandwich gaskets utilizing naturally occurring pyrophyllite and a steel cone to achieve single-stage multistaging, pressure containment, and electrical and thermal insulation.
Implemented resistive sample heating via electric current passed through an internal metal or graphite tube alongside standardized temperature and pressure calibration procedures.
Maintained static pressures of 100,000 atmospheres concurrently with temperatures exceeding 2000°C for extended periods of time.
Achieved durable pressure sealing and axial piston travel without structural failure via the compressible pyrophyllite-steel gasket assembly.
