Deuterium

Formula: 2H, D2

What is Deuterium?

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.

Does Deuterium Occur Naturally?

Deuterium is produced for industrial use but does exist naturally. 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). This is the ratio found in gas giant planets, such as Jupiter.

FAQs about Deuterium

Is deuterium gas safe?

Deuterium is flammable and poses a threat of asphyxiation when inhaled, however, is still considered a non-toxic and stable gas. EFC’s culture of safety ensures that deuterium is always handled correctly, safely, and according to industry standards.  

Where is deuterium gas found?

On Earth, deuterium exists in liquid form in ocean water. Dueterium is made in space. It is present on gas giant planets in our solar system and is present in comets. It is theorized that deuterium played a large role in the Big Bang.
