Device for Ultra-High-Pressure High-Temperature Research

Abstract

A new device has been developed for materials research at high pressures and high temperatures. The unit may be described as an extension of the Bridgman ``anvil,'' modified to permit internal heating. The principle of ``massive support'' is retained with pressure being achieved through the elasticity of multiple binding rings, rather than through the ``compressible'' gasket effect. The unit has been calibrated to pressures beyond 100 000 atm with temperature to 2000°C. The operational characteristics of the device and problems associated with high-pressure high-temperature research are discussed.
