Chinese scientists successfully synthesize fluid metal hydrogen

Reporters from the Chinese Academy of Sciences Hefei Institute of Material Sciences was informed that the Institute of Solid Physics Extreme Environmental Quantum Matter Center team in extreme high temperature and high pressure conditions successfully obtained hydrogen and radon metal state. The results of the research have been published in the international important academic journal Advanced Science. This is another important breakthrough in the study of high pressure in light elements, following the successful synthesis of fluid metal nitrogen by the Quantum Center of the Institute of Solid Physics.

Chinese scientists successfully synthesize fluid metal hydrogen

In 2015 and 2018, two U.S. laboratories observed the fluid metal states of hydrogen and thorium, published in the journal Science, respectively, but the temperature and pressure curves reported by the two varied widely to determine exactly where fluid metal hydrogen existed.

On the basis of the previous work, researchers from the Quantum Center of the Solid Institute of the Hefei Institute of the Chinese Academy of Sciences, based on the diamond-to-top crucible device and combined with pulsed laser heating technology, created in the laboratory extreme temperature pressure conditions that can simulate the geocore, and successfully transformed the hydrogen and thorium of the gaseous state into a fluid metal state. The optical absorption and reflection characteristics of the sample were detected by ultra-fast broadband ultra-continuous spectra, and the physical characteristics of the optical and electrical properties of hydroium and thorium were revealed. The results of the study identify the existence areas of hydroand radon in fluid metals and further indicate that this metal state requires a considerable wide range of high temperature and high pressure semi-metallic areas to be obtained.

The project has been supported by the National Natural Science Foundation of China,its projects, the national major instrument development projects and other projects.
