A mid-term appraisal on a research project Synchrotron Radiation High Pressure and High Temperature Experimental Techniques and Physical Study of Important Minerals in the Earth's Mantle and Core was recently held in Beijing..
Jointly supported by the CAS Bureau of Basic Sciences and the CAS Bureau of Resources and Environment, the project was started in 2002 by researchers from the CAS Institute of High Energy with an objective to provide high temperature and high pressure research means in studying the material structure of the earth's inner part and material science. technical platform under extreme conditions for geologists and high-pressure researchers.
As a result of nearly three years of hard work, a laser-heating experimental system for in-situ X-ray diffraction was established, becoming one of the three open DAS (diamond-anvil cell) systems in the world. In addition, it inaugurated the internationally second testing system capable of carrying out supersonic measurement at a micro-anvil and conducted a series of high-level tests such as the graphite melt under the pressure of 2.7Gpa and the structure and phase change of minerals in the earth's mantle.
