- Thallium is a
chemical element with the symbol Tl and atomic number 81.
- Thallium occurs in
crooksite, lorandite, and hutchinsonite.
- In its pure form,
thallium is odorless and tasteless.
- Thallium is very
soft and melts easily.
- It is soft
enough to cut with an ordinary knife and will leave a mark on paper if
rubbed across it.
-
The thallium-based and mercury-based superconducting
oxides are excellent candidates because of their high transition
temperature reaching to 130 K and unique features in their growth
morphology.
-
It is also
present in pyrites and is recovered from the roasting of this ore in
connection with the production of sulfuric acid.
- Thallium is a
byproduct metal recovered in some countries from flue dusts and residues
collected in the smelting of copper, zinc, and lead ores.
- Thallium is obtained
as a by-product of the recovery of lead and zinc.
- Gases from the
recovery process are captured. They are then treated to obtain the pure
metal.
- Thallium is
recovered as a byproduct from the flue dust and residues generated
during the roasting and smelting steps in the processing of copper,
lead, zinc, and other sulfide ores.
- Approximately 60-70%
of thallium production is used in the electronics industry, and the rest
is used in the pharmaceutical industry and in glass
manufacturing.
- Thallium is highly
toxic and is used in rat poisons and insecticides, and its use has been
cut back or eliminated in many countries.
- Thallium is used in
the electrodes in dissolved oxygen analyzers.
- Thallium has been
used in treating ringworm and other skin infections
- its use has
been limited because of the narrow margin between toxicity and
therapeutic benefits.
- Thallium has been
used, with sulfur or selenium and arsenic, to produce low melting
glasses which becomes fluid between 125 and 150 C.
- Thallium amalgam is
used in thermometers for low temperature, because it freezes at -58
°C.
- World resources of
thallium contained in zinc resources total about 17 million kilograms;
most are located in Canada, Europe, and the United States.
- Higher internal
demand for many metals, including thallium, has prompted China to begin
importing greater quantities of thallium.
-
The recent introduction of
thallium-20i /Tc-99m pertechnetate subtraction scintigraphy for imaging
parathyroid adenomashas rekindled interest in parathyroid
scintigraphy.
-
Some reports have described both
positive and negative thallium-201 accumulation in thymic
rebound.
-
Although more experience with
similar cases is necessary, it is likely that thallium-201 also tends to
accumulate in thymic rebound as well as gallium.
