Deuterium oxide CAS NO.7789-20-0

Main use and function

Deuterium oxide can be used as neutron moderator and heat carrier in nuclear fission reactors and can also be used in chemical and biological research. The deuterium from heavy water electrolysis is the charging of hydrogen bombs.
Heavy water is mainly used as moderator in nuclear reactor to reduce the neutron velocity and control the nuclear fission process and also as coolant. Heavy water and deuterium are valuable tracer materials in the study of chemical and physiological changes. For example, diluted heavy water can run from more than ten meters to tens of meters per hour after irrigating trees with dilute water. The heavy water molecule can stay in human body for 14 days on average after measuring the content of deuterium in the urine of human drinking a large amount of diluted water. Deuterium can be used to research the digestion and metabolism of animal and plant instead of ordinary hydrogen. Concentrated or pure heavy water can not maintain the life of animals and plants and heavy water lead animal and plant to death at the concentration of 60%.
