Formula: H2 (D2)
The name deuterium is derived from the Greek deuteros, meaning “second”, to denote the two particles composing the nucleus. Deuterium was discovered and named in 1931 by Harold Urey.
Soon after deuterium’s discovery, Urey and others produced samples of “heavy water” in which the deuterium content had been highly concentrated. Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago, as the basic or primordial ratio of hydrogen-1 to deuterium (about 26 atoms of deuterium per million hydrogen atoms) has its origin from that time. This is the ratio found in the gas giant planets, such as Jupiter.
- Used in nuclear power, fusion power, lasers and lighting.
- Used to prepare deuterated biological compounds, deuterated lubricants, deuterated optical fibers, and in electronics as a replacement for hydrogen in the annealing or sintering of silicon based semiconductors, flat panel displays, and solar panels
- Used in reaction rate studies and exchange reaction studies
