Deuterium History
The existence of nonradioactive isotopes of lighter elements had been suspected in studies of neon in 1913, In 1920 it proven by mass spectroscopy of light elements. It was expected that hydrogen, with a measured average atomic mass very close to 1 u, and a nucleus thought to be composed of a single proton, could not contain nuclear electrons, and thus could have no heavy isotopes.
Deuterium (CAS NO.7782-39-0) was predicted in 1926 by Walter Russell, using his "spiral" periodic table. It was first detected spectroscopically in late 1931 by Harold Urey from Columbia University. Gilbert Newton Lewis prepared the first samples of pure heavy water in 1933. after the neutron was reported, deuterium won Urey the Nobel Prize in chemistry in 1934.
Deuterium Uses
Deuterium (CAS NO.7782-39-0) is useful in nuclear fusion reactions, especially in combination with tritium. There is an even higher-yield D–3He fusion reaction, though the breakeven point of D–3He is higher than that of most other fusion reactions; together with the scarcity of 3He, this makes it implausible as a practical power source until at least D–T and D–D fusion reactions have been performed on a commercial scale.
As liquid D2O,Deuterium is used in heavy water moderated fission reactors, to slow neutrons without high neutron absorption of ordinary hydrogen.
Deuterium Safety Profile
