Deuterium
Deuterium
Formula: D2, ²H
CAS No: 7782-39-0
Deuterium (D2) is an isotope of hydrogen containing one proton and one neutron in its nucleus. Naturally occurring deuterium was formed during the Big Bang and makes up about 0.015% of hydrogen found on Earth—roughly 26 atoms of deuterium per million hydrogen atoms. It is present in water, gases, and other hydrogen-containing compounds, and is also produced for industrial and research purposes.
Applications include:
-
Neutron moderation in nuclear reactors and research facilities.
-
Isotopic labeling for tracer studies in chemical, pharmaceutical, and biochemical research.
-
Fusion fuel component in experimental energy systems.
-
Non-radioactive isotope for spectroscopy, NMR, and mass spectrometry calibration.
-
Process gas in semiconductor manufacturing, including plasma processing and thin-film deposition.
EFC Gases & Advanced Materials supplies high-purity deuterium gas to meet the exacting requirements of nuclear, research, semiconductor, and specialty industrial applications. Our controlled packaging, rigorous analytical verification, and secure supply chain ensure consistent quality from production to delivery.
