heavy water


Sinonimi: deuterium oxide

Water containing a substantial proportion of deuterium atoms, used in nuclear reactors; SYN. deuterium oxide.
Or deuterium oxide; D2O water containing the isotope deuterium instead of hydrogen (molecular weight 20 as opposed to 18 for ordinary water).
Its chemical properties are identical with those of ordinary water, but its physical properties differ slightly. It occurs in ordinary water in the ratio of about one part by mass of deuterium to 5,000 parts by mass of hydrogen, and can be concentrated by electrolysis, the ordinary water being more readily decomposed by this means than the heavy water. It has been used in the nuclear industry because it can slow down fast neutrons, thereby controlling the chain reaction.
