In the field of aerospace, xenon bears the heavy responsibility of adjusting the posture and orbit of satellites in space. For a long time, the xenon used in the field of electric propulsion in the launch of China's space satellites has been dependent on imports. The development of xenon technology and the promotion of the localization of "aerospace xenon" are important issues.
The high-purity xenon microwater index required in the original national standard requires that it reach the first-class product standard only at 1ppm. However, the new requirements put forward by China's scientific research institutes and design units are that the purity must reach less than 0.1ppm, that is, 99.9999%.
HBIS has set up a special technical research team, completed more than ten improvements, conducted more than 100 tests, overcome the technical problems of purity control, and reduced the cleanliness of high-purity xenon to less than 0.1ppm.
In the first half of 2019, the electric propulsion test of the core module of a space station project of China Aerospace Science and Technology Group was successful, and the propellant "aerospace xenon" used in the core module was all supplied by Hesteel, which was the first time that domestic xenon was used as a propellant in the national space station project.
At the same time, the technical team has also tackled the purification of a variety of special gases, and the purity of rare gases such as krypton, xenon, neon and helium has reached 99.9999%.
