Explanation

Hydrogen isotope deuterium and oxygen compound, molecular weight 20. Its physical and chemical properties are slightly different from that of ordinary water, with a melting point of 3.82 ° C and a boiling point of 101.42 ° C. Ordinary water accounts for about 0.015%. Production is the separation process of hydrogen isotopes. See deuterium for its preparation method, nuclear performance and use.
