2. Thorium
Thorium resources are found
throughout the world, most
notably in Australia, Brazil,
India, and the United States.
India has the largest
resources (850,000 tons),
followed by Brazil (630,000
tons) and Australia and the
United States (600,000 tons
each).
Thorium’s use in
most products
was generally
limited because
of concerns
over its naturally
occurring
radioactivity
The world’s
primary source of
thorium is the rare-
earth and thorium
phosphate mineral
monazite.
Commercial uses of thorium include catalysts,
high-temperature ceramics, magnetrons in
microwave ovens, metal-halide lamps, nuclear
medicine, optical coatings, tungsten filaments,
and welding electrodes.

3. • Thorium is used to
make ceramics, lantern
mantles, welding rods,
camera and telescope lenses,
and metals used in the
aerospace industry.
• Thorium is more abundant in
nature than uranium.
• It is fertile rather than fissile, and
can only be used as a fuel in
conjunction with a fissile
material such as recycled
plutonium.
• Thorium fuels can breed fissile
uranium-233 to be used in
various kinds of nuclear
reactors.

5. • Thorium Acetate Solutions are
moderate to highly
concentrated liquid solutions
of Thorium Acetate.
• They are an excellent source of
Thorium Acetate for
applications requiring
solubilized materials.
• Acetates are excellent
precursors for production of
ultra high purity compounds
and certain catalyst and
nanoscale (nanoparticles and
nano powders) materials.
• Acetates are also proving
useful in the field of solar
energy technologies

6. Thorium Bromide, ThBr4
Thorium Bromide, ThBr4, is prepared similarly to
the chloride, i.e. by the union of its elements, by
acting on a heated mixture of thoria and carbon
with bromine vapor, and by brominating thorium
carbide at high temperature (Moissan and
Martinsen). It may also obtained conveniently by
the method of Bourion, which is generally
applicable to the preparation of anhydrous
metallic bromides from their oxides. This method
consists in the simultaneous action of Sulphur
chloride vapor and hydrogen bromide on the
metallic oxide heated to a suitable temperature.
Thus a white mass of ThBr4 is obtained when
Sulphur chloride vapor at 135° C., mixed with
hydrogen bromide, is distilled on to heated thoria,
whilst if the temperature is lowered to 125°
C. ThOBr2 results.
