Abstract:

Abstract:  Recent progress in both high pressuretemperature experimental techniques and insitu measurement techniques under high pressure temperature were discussed. In this paper, we focused on the following aspects: (1) The characteristics of both static and dynamic high pressure techniques, i.e. diamond anvil cell, large volume press, and autoclave; (2) Spectroscopy used in high pressure techniques for insitu measurement, including Raman, Infrared, Xray diffraction and synchrotron radiation; (3) Experimental methods for determining elastic wave velocity under high pressure-temperature, i.e. ultrasonic method, Brillouin Scattering, Nuclear Resonant Inelastic XRay Scattering; (4) The recent development of insitu measurement of electrical conductivity under high pressuretemperature in diamond anvil cell and large volume press.
