Effects of High Pressure on Glass: a Possible Piezometer for the 100-Kilobar Region

Abstract

THE measurement of pressures of the order of 10,000–200,000 bars and upward on uniaxial pressure transmitting devices is a formidable problem. At present, inter-laboratory comparison of results obtained at ultra-high pressures is not satisfactory. The availability of a convenient pressure calibration substance that is useful over a wide temperature-range, and the agreement on a satisfactory scale of pressure based on this calibration substance, are imperative for future work.
