Isotopic gas refers to the gas with the same number of protons, different numbers of neutrons (or different mass numbers) of the same element of different nuclides isotope gas.Helium isotope gases include helium-3, helium-4, helium-5, helium-6, helium-7, helium-8, helium-9, and helium-10.But only helium-3 and helium-4 are stable, the rest are radioactive.Both helium-3 and helium-4 isotope gases have their own specific fields of use.
Helium-3 (Helium-3) is an unstable nucleus containing two protons and one neutron. It may break down by beta decay, producing a lithium-7 nucleus.
Helium-3 is produced in large quantities in nuclear fusion reactions in the Sun and stars, and it can also be produced on Earth through the decay of radioactive elements such as uranium and thorium.
In the nuclear sector: Helium-3 can be used as a clean energy source for nuclear fusion reactions that produce large amounts of energy without producing long-lived radioactive waste. In the field of nuclear fusion research, helium-3 is an important nuclear fusion fuel that can simulate the nuclear reactions of the sun and stars, so it is widely used in the field of energy research.
Superconducting magnet cooling: Helium-3 can be used for the cooling of superconducting magnets, which is particularly important in high-energy physics experimental techniques and deep space exploration technologies.
Helium-4 is a stable isotopic gas that makes up more than 99% of the helium in the atmosphere. Because of its chemical inertia, helium-4 does not form compounds with other elements, so it is widely used in fields such as cooling, hovercraft, optics and insulation materials. Helium-4 is commonly used for low-temperature experiments and for cooling equipment, such as superconducting magnets and nuclear magnetic resonance instruments. Helium-3 is also used in some special nuclear magnetic resonance experiments to study the properties of matter. Helium-4, as the main component of helium in the Earth’s atmosphere, accounting for about 99.99986% of helium, is mainly used in refrigeration technology: Helium-4 is widely used in refrigeration technology because of its extremely low boiling point (-268.9 ° C).
