[observer network comprehensive report] according to the "science and Technology Daily" reported in July 9th, the Hefei Institute of Physical Science.CAS of the Chinese Academy of Sciences was informed that the researchers of the Alexander Goncharov team of the Institute of solid physics of the Institute have successfully synthesized the super high energy materials, polymerized nitrogen and "metal nitrogen", the energy density of these two materials is TNT More than 10 times. The research reveals the critical conditions for the synthesis of metal nitrogen, such as extreme conditions, transformation mechanism and photoelectric characteristics. China's high-energy materials research is further advancing towards the "N2 bomb" and "metal hydrogen". The results were recently published in the journal Nature.
The explosive bomb that only produces N2 (nitrogen) after explosion is called N2 explosive bomb.
The new super high energy energetic material is an important symbol of the national core military capability and the commanding height of military technology. Nitrogen compounds have the advantages of high density, super high energy, and clean and pollution-free detonation products. They are typical representatives of the new generation of ultra-high energy energetic materials. At the beginning of 2017, the former South physics Hu Bingcheng team synthesized a total nitrogen anion salt of 3 times the energy density of TNT. The research direction of the team was pointing to the formation of polymeric nitrogen and "metal nitrogen" under extreme high temperature and high pressure conditions.
Alexander Goncharov, a Russian born researcher, born in Russia, was born in November 29, 1956, graduated from the physics major of the Institute of spectroscopy and science of the Russian Academy of Sciences in 1983, and was selected by the Central Organization Department of the Communist Party of China in 2012 as "a thousand foreign experts plan". In 2015, he was awarded the "Friendship Award" of the Chinese government. Ma Kai, vice premier of the State Council, presented the award to Mr.
These two kinds of nitrogen materials are typical super high energy materials, which are more than ten times of the current TNT energy density. If they can be used as fuel for manned rocket one or two stage propeller, it is expected to increase the take-off weight of rockets several times more than that of the current. However, "metal nitrogen" is not readily available, requiring extreme high pressure up to GPa and high temperature conditions of several thousand degrees.
The commonly used device for preparing ultrahigh pressure materials is diamond anvil, which can produce high pressure over the earth's center.
The science and Technology Daily reported that the researchers, using ordinary nitrogen as raw materials, introduced pulse laser heating and ultrafast spectral detection methods on the basis of the original diamond to top anvil device, and built an in situ comprehensive experimental system for the measurement of transitivity of high temperature and high pressure. Using the comprehensive experimental system, the researchers obtained the extreme conditions of high temperature and high pressure of up to 170GPa and 8000K. Under this condition, the optical absorption and reflection properties of nitrogen molecules in the process of insulator semiconductor metal transition were studied in situ. The phase boundary of nitrogen molecular dissociation and the extreme pressure of "metal nitrogen" synthesis were determined. In the range of temperature conditions, the in situ spectroscopic analysis has further confirmed that the semi metal properties of the polymerized nitrogen and the "metal nitrogen" with the perfect metal properties have been confirmed in the experiment.
A researcher with a postdoctoral researcher is working on a laser heating experiment under high pressure.
The results of the team of the gang not only provide guidance for the synthesis of other forms of high energy nitrogen materials, but also provide an important basis for the successful synthesis of "metal hydrogen" in the future. Because the extreme high temperature and high pressure conditions required for the synthesis of "metal hydrogen" are similar to that of synthetic "metal nitrogen".
"Metal hydrogen" is known as the Holy Grail of high energy physics because of its theoretical high energy density (50 times of TNT explosive) and high temperature superconductivity (possibly at -113.15 C or even 16.85 C), and the Institute of solid physics is close to the "Holy Grail".
In January 2017, the Harvard University research team once claimed to have successfully made the world's first "metal hydrogen" under the high pressure of the 495GPa under the high pressure of the diamond anvil device, but many people in the academia (including fell. gang chrov) questioned the fact that the anvil could not be so high as to rely solely on the diamond on the anvil. There is also insufficient evidence for the existence of so-called "metal hydrogen". However, in February of that year, the Harvard University team announced that the "metal hydrogen" sample disappeared because of the damage of the diamond container. The real existence of the first piece of metal hydrogen has become a mystery. "The Holy Grail of high-pressure physics" remains to be sought by later generations.
