Definition
- Noun:
- Heavy water: Deuterium oxide is a form of water where the hydrogen atoms are replaced by deuterium atoms (a heavier isotope of hydrogen). It is used as a moderator and coolant in certain types of nuclear reactors.
Usage Examples
- Noun:
- The nuclear reactor uses deuterium oxide as a neutron moderator.
- Scientists analyzed the sample of deuterium oxide in the laboratory.
Advanced Usage
- Scientific Context: The term is primarily used in chemistry and nuclear physics. It is often discussed in relation to nuclear fission, neutron moderation, and isotopic studies.
- The properties of deuterium oxide differ slightly from those of ordinary water.
Variants and Related Words
- Heavy water (n): A common synonym for deuterium oxide.
- Deuterium (n): The hydrogen isotope (with one neutron) that is a component of deuterium oxide.
- Light water (n): Ordinary water (H₂O), often contrasted with heavy water in scientific contexts.
Synonyms
- Heavy water: The most direct and commonly used synonym.
Related Phrases
- (To) moderate neutrons: A key function of deuterium oxide in nuclear reactors.
- The reactor core is designed to use deuterium oxide to moderate neutrons effectively.
Noun
-
water containing a substantial proportion of deuterium atoms, used in nuclear reactors
