On the blue planet we live in, there is a gas that is extremely rare, but it is an indispensable element at the forefront of science and technology and in daily life. This gas is helium. Recently, Chinese researchers have successfully extracted high-purity helium from coal seams, with a purity of up to 99999%, this major breakthrough means that China has gotten rid of its dependence on imports on helium** and is moving towards a new era of self-sufficiency.
The rarity and rarity of helium
The amount of helium in the Earth's atmosphere is extremely low, accounting for only 51 in 20,000. This makes helium a truly rare gas, especially in the context of the growing demand for helium in industrial production and scientific applications. This rarity also means that the extraction of helium is extremely difficult and requires a high degree of technology and precision.
Difficulty of extracting helium
The extraction of helium is not easy. It is often mixed with natural gas or other gases in the coal seam and requires several complex processes to obtain high-purity helium. This requires not only advanced equipment and technology, but also rigorous screening and processing of raw materials. Because of this, helium has been in short supply in the global market,** and is relatively high.
Areas of application for helium
Although helium is rare and difficult to extract, it plays an important role in many key areas. First of all, helium is indispensable in deep-sea diving and aerospace. As a breathing gas, helium protects divers from nitrogen intoxication in the deep sea and provides a safe breathing environment for astronauts. In addition, helium is also a key factor in technological advancements such as superconductivity research and magnetic resonance imaging. In the medical field, helium is used for certain lung diseases and cancers, while in industrial production, it is used in areas such as metal welding, fiber optic manufacturing, and the electronics industry.
The great significance of extracting helium
The breakthrough of China's first successful extraction of high-purity helium from coal seams is of great significance. This breakthrough means that China has gotten rid of its dependence on imports on helium, and has enhanced China's ability to independently guarantee resources. The self-sufficiency of high-purity helium will further promote China's development in the fields of deep-sea diving, aerospace, health care, scientific research and industrial production, and enhance China's comprehensive national strength and competitiveness.
China's science and technology is worthy of pride and expectation!
