The development of high - pressure science strongly dependent on technological breakthroughs and innovation of high temperature and high pressure diamond anvil high-pressure high-temperature technology is one of the important problems that need to be resolved in the high-pressure technology . Greatly promote the role and importance of the development of new technology for high-temperature high-pressure experiments on high pressure science . The basis of this thesis, the author summarizes the previous high-temperature and high-pressure experimental study on the establishment of a new gasket heating technology of high-temperature high-pressure experiments . Diamond anvil device (DAC) 5GPa, 1200K and 0.2 GPa , 1500K high temperature and high pressure experimental conditions . The use of this new type of high temperature and high pressure experimental techniques , high-temperature and high-pressure Raman spectroscopy study of igneous rocks of the important ingredients - natural feldspar sanidine . Was found to 6.7GPa when sanidine Raman peaks mutations in 19GPa sanidine Shifa Sheng an amorphous phase change . Buck experimental results show that the amorphous phase remains to the atmospheric state, the phase change is irreversible . The technology of high-temperature high-pressure experiments using a new gasket heat sanidine 0.3GPa, 1400K situ high-temperature and high-pressure Raman experiments . 5GPa the role of temperature was raised to 1100K process of its Raman spectrum with the temperature changes , there is obtained an irreversible amorphous phase sanidine . Thus illustrate the feasibility of the DAC high temperature and high pressure experimental techniques under the new high-pressure heated way .
