deuterium oxide


Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia, Wikipedia.

heav·y wa·ter

D2O; water in which the hydrogen atoms are deuterium, or heavy hydrogen (2H), with physical properties that differ noticeably from those of ordinary water; an elevated presence will cause a decrease in metabolic activity; used as a moderator in nuclear reactors because of its capacity to absorb neutrons.
Synonym(s): deuterium oxide

deuterium oxide

An isotope of water in which hydrogen has been displaced by its isotope deuterium. Its properties differ from ordinary water in that it has higher freezing and boiling points and is incapable of supporting life.
CAS # 7789-20-0
Synonym: heavy water
