First, the global distribution of helium
Helium in China accounts for 2%
Second, the mainland's 21-year helium imports
Main uses:
1. MrI
Mr. NMR, helium is indispensable.
2. Semiconductors
Helium is an inert gas gas that avoids unexpected reactions. In addition, due to the high thermal conductivity of helium, it can also dissipate heat efficiently, which can reduce the temperature of the silicon wafer during semiconductor manufacturing.
3. Rocket launch
Helium is also an important material for space development. It is used as a refrigerant to cool many materials and weld precisely, and as a gas sealant for liquid systems for aircraft flying or landing.
As a strategic gas resource, helium is also an important part of chip manufacturing, with the mainland's annual demand of more than 4,000 tons, but more than 95% of it depends on imports from the United States, Qatar, Australia and other countries.
