Latest development of static high pressure technology in China and abroad

High pressure is divided into dynamic (shock wave) high pressure and static high pressure, while static high pressure is divided into small volume press like as diamond anvil cell (DAC) and large volume press (LVP). Under high pressure, materials exhibit completely different properties under normal temperature and pressure. Through high pressure research, we can systematically understand the phase transition and compression behavior of various materials under pressure. Therefore, high pressure has been widely used in materials science, geophysics, planetary science, national defense and other fields. According to the survey, the current foreign DAC can exceed the pressure of 500 GPa, the pressure in large volume press (LVP) can reach the pressure of 125 GPa, and the domestic pressure can reach the pressure of 35 GPa. This paper systematically summarizes the temperature, pressure range and design principles of high-pressure devices at home and abroad to reveal the development history of static high-pressure science. Summarizing the temperature and pressure limits of various static high-pressure equipment at home and abroad not only allows us to have a clearer understanding of international and domestic high-pressure development trends.
