Deuterium gas, also known as heavy hydrogen, is a colorless, odorless, non-toxic combustible gas at room temperature and pressure. It is a stable isotope of ordinary hydrogen. It contains 0.0139% to 0.0157% of hydrogen in ordinary water. Its chemical properties are exactly the same as ordinary hydrogen. However, due to its large mass, the reaction rate is slower. It is mainly used for special light bulbs, nuclear research, bombardment particles of deuterium nuclear accelerators, tracers, and 1-3% D2+N2 ​​mixed gas is widely used in low water peak optical fiber processing.
