Some thorium uses:
- fertile material (as ThO2) in nuclear power reactors; is a precursor of the fissile isotope 233U.
- thorium dioxide can be used as refractory material for crucibles, tubes, rods, etc.
- thorium tetrafluoride (ThF4) is used as anti-reflection coating in optics.
- gas mantles (as ThO2)
- alloying metal for some aviation components (magnesium-thorium alloy, magnesium-zinc-thorium); also for welding alloys wolfram-thorium
- additive (as ThO2) in wolfram filaments - to stop crystalline growth of W and to increase time of use of light bulbs
- catalyst in organic chemistry (as ThO2)
- additive for special glass (as ThO2)
- additive in filaments (as ThO2) of magnetron tubes, vacuum tubes - reagent in chemistry laboratories (as thorium nitrate)
- etc.
Common compounds of thorium: thorium dioxide, thorium trifluoride, thorium tetrafluoride, thorium tetrachloride, thorium triiodide, thorium diiodide, thorium tetraiodide, thorium nitrate, thorium oxalate, thorium carbide, thorium sulfides, thorium nitride, thorium oxinate, etc.
The chemical symbol of thorium is Th.
232Th has 142 neutrons and 90 protons and electrons.
Thorium (Th).
Yes, it is legal to own thorium in the form of thorium compounds or products that contain thorium. However, regulations vary by country and region, so it is important to check local laws and regulations before acquiring or possessing thorium.
Of course, thorium is a controlled material and working with thorium is not a joke for home.

thorium is breed to make uranium-233 fuel
O: Thorium oxide, ThO2 - many important uses, see the link F: Thorium tetrafluoride, ThF4 - used as antireflection layer in optics C: Thorium carbide, ThC - used as nuclear fuel
Thorium and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
Hazards and Health Considerations: Thorium presents both a toxic and radiological hazard. Toxicologically, it causes heavy metal poisoning similar to lead or the uranium isotopes. Biologically, thorium accumulates in the skeletal system where it has a biological half-life of 200 years, the same as plutonium. An M 17 protective mask and standard anti-contamination clothing will adequately protect against thorium.
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
Also thorium.
The chemical symbol of thorium is Th.
232Th has 142 neutrons and 90 protons and electrons.
Thorium as a metal is obtained by a calciothermic process from thorium dioxide. Other methods are: electrolysis of thorium tetrafluoride and thermal decomposition of thorium tetraiodide (Van Arkel-de Boer process).
Thorium (Th) is a member of the actinoids family.
