The Key Laboratory of High Temperature and High Pressure of Earth's Interior Materials of the Chinese Academy of Sciences uses high temperature and high pressure experiments as the main research method, combined with field observations, theoretical calculations and modern analysis and testing, to explore the general laws of the composition, structure, texture, properties and changes of the Earth's interior material system under high temperature and high pressure conditions, and closely serve the national economy, national goals and national security such as energy resource exploration and efficient and clean utilization, geological disaster prediction, greenhouse gas geological landfill, "three depths" detection, material synthesis, metal corrosion and protection, and engineering physics. Main research directions: research and development of high temperature and high pressure experimental platform and in-situ observation technology; synthesis and hot pressing sintering of high temperature/high pressure materials; experimental and theoretical calculation research on the phase composition, structure, texture and physical properties of minerals and rocks in the Earth's interior under high temperature and high pressure (with and without differential stress); high temperature and high pressure experimental research on the structure, properties of water fluids and melts in the Earth's interior, and the occurrence state and physicochemical behavior of dissolved substances therein; experimental and theoretical calculation research on the interaction between materials in the Earth's interior under high temperature and high pressure (with and without differential stress); application research of high temperature and high pressure experimental platform and technology and high temperature and high pressure experimental results to serve the national economy, national goals and national security.
