Neptunium has only limited uses:
- precursor in the preparation of plutonium-238
- sensor in the detectors of high energy neutrons
In USA are studied applications of neptunium in nuclear weapons or as nuclear fuels for fast reactors.
Neptunium trifluoride is an intermediate for the preparation of neptunium metal.
Neptunium is a metal.
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
Neptunium is an individual element; isotopes of neptunium are not separated.
Neptunium(IV) oxide or neptunium dioxide is the chemical compound composed of neptunium and oxygen with the formula NpO2. It forms dark olive[4] green cubic crystals[1].
Yes, neptunium is a metal.
Neptunium is not in foods.
No use today; neptunium trifluoride is used to prepare neptunium metal.
Neptunium is an artificial element.Amounts of natural neptunium are absolutely nonsignificant.
