Heavy Water


  • It is also known as deuterium oxide (D2O).
  • It is form of water that contains large amount of hydrogen isotope deuterium (heavy hydrogen).
  • Deuterium differs from hydrogen which is usually found in water.
  • Heavy water may be deuterium protium oxide (DHO) or deuterium oxide (D2O).
  • The presence of deuterium increase mass of water and gives different chemical and physical property compared to normal water.
  • Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons.
  • It also used in nuclear magnetic resonance, organic chemistry, fourier transform spectroscopy, neutron moderator, neutrino detector, tritium production and metabolic rate testing in physiology and biology.
