On the eve of the Mid -Autumn Festival, the Chinese National Space Administration and the National Atomic Energy Agency jointly released the latest scientific achievements in Chang'e 5 in Beijing on Friday (September 9): The new minerals found on the moon for the first time by Chinese scientists were named "Chang'e Stone"EssenceThe mineral is the sixth new mineral found on the moon, and China has become the third country in the world to discover new minerals in the moon.
According to Chinanews.com, on December 17, 2020, China Chang'e 5 moon probe successfully returned to the earth with 1731 grams of "local products".The sample also makes China the third country to successfully collect lunar samples.
In June last year, the Chang'e 5 moon sample opened an application to the whole society.Nuclear Research Institute is one of the first 13 research institutions that have obtained lunar samples. There are three topics approved, namely "Study on Chang'e 5 Moon Sample Fusion Nuclear Energy Nuclear (3HE)" and "Chang'e 5 Moon SampleThe study of uranium (核) nuclear and isotope "and" the study and significance of the nuclear element of the moon nuclear element "; the goal is to carry out the basic geological research of independent lunar fission, fusion resource basic geological research, and provide important basic data for lunar evolution and lunar resource evaluation.
In the process of carried out mineral research on the first batch of monthly soil powder samples, the scientific research team of nuclear ground research institutes discovered the clues of new minerals.At that time, it was a particle of about 10 microns. It interacted with pyroxyl interacting together. There was no way to remove the pylori regardless of experimental means or later data processing, so it has not obtained the ideal structural data.
After applying for the second month of soil samples, the scientific research team counted 140,000 granules on the target of the sample and found some traces of new minerals, but there is only one one who has a single crystal structure.And this one is still cracking into three small pieces.In the end, the team cut out a pure single crystal particles of 10*7*4 microns, that is, the average diameter of ordinary people's hair was less than one tenth of the average diameter of ordinary people.
Researchers subsequently transferred particles to the single crystal diffraction instrument to collect diffraction data, and finally interpreted the crystal structure of new minerals.They carried out Laman spectrum analysis, crystal light description, physical properties, etc. of new minerals, and determined that it was a new mineral that has never been discovered through systematic mineral research.
This new lunar mineral is named "Chang'e Stone", and its English name is Changesite- (Y), which is Change (Chang'e's Chinese Pinyin)+S+ITE (English suffix)+Y (Special ingredient suffix).
"Chang'e Stone" was found in the basalt debris of Chang'e 5, which is a new phosphate mineral, which belongs to the meteorphosonic phosphate sodium and magnesium calcium (Merrillite) family.The ideal chemical formula is (CA8Y) □ Fe2+ (PO4) 7, the crystal structure belongs to the three -party crystal system, and the space group R3C.The particles are about 2 ~ 30 microns, with tiny columnar. The accompanying minerals include iron olives, single -diagonal pyroxyl, titanium iron ore, calcium long stone, oblique stone, square quartz, meteorite iron and glass.
The research report of the Nuclear Research Institute's research team was submitted to the new mineral classification and naming committee of the International Mineral Society.In August 2022, the New Mineral Classification and Naming Committee of the International Mineral Society passed the Chang'e Stone Research Report and issued a approval letter.
The new mineral (Changesite- (Y)), a new mineral (Y), which was appraised by 20 mineral scientists from many countries, was reviewed by 20 mineral scientists from multiple countries.Daily obtained the official approval of the New Mineral Classification and Naming Committee (CNMNC) of the International Mineral Society (IMA), with the approval number of IMA2022-023A.
