Thorium is a natural chemical element.
Thorium oxide is not particularly expensive. Thorium metal is very expensive, but this may be because there is so little demand for it that it has to be specially made when someone wants it.
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.
A hypothesis
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 and fluorine Thorium trifluoride - ThF3 Thorium tetrafluoride - ThF4
what are the laboratory apparatus that are made up of ceramics
Thorium don't smell.
Thorium (Th).
How many radioactive elements are made only in a laboratory?
Thorium is a natural, radioactive, chemical element; chemically, thorium is homogeneous.
Thorium-232 is appearing in the thorium series.
Thorium: soft but strong! Thorium is totally radioactive!
