- Tellurium is a
metalloid chemical element which is used in a variety of industries,
primarily in the form of an additive to an assortment of compounds and
alloys.
- Tellurium symbol is Te
and atomic number 52. A brittle silver-white metalloid which looks like
tin, tellurium is chemically related to selenium and sulfur. Tellurium
is primarily used in alloys and as a semiconductor
- It is relatively rare
on the Earth's surface, and it is usually found in combination with
other materials, such as gold.
Tellurium can be isolated through
chemical or electrolytic processes. Because of its rarity, the element
can be expensive, especially in a pure form.
- Tellurium and its
compounds are probably toxic and should be handled with care. Workmen
exposed to as little as 0.01 mg/m3 of air, or less, develop "tellurium
breath," which has a garlic-like odor.
- Tellurium is obtained
as a byproduct of the electrolytic refining of copper. Although copper
slimes are valued primarily for gold, silver, and occasionally
platinum-group metals, tellurium is available to the refiner for the
added cost of recovery and refining.
- The process flow for
the production of tellurium can be separated into two stages. The first
stage involves the removal of copper from the copper slimes (an
intermediary product is tellurous acid). The second stage involves the
recovery of tellurium metal and purification of the recovered
tellurium.
- A common method for
obtaining tellurium is to pass an electric current through dissolved
tellurium dioxide (TeO2). The current breaks the tellurium dioxide down
into oxygen and tellurium
- Absorbance of the
coloured extracts of the tellurium ion associates depends on the nature
of the extractant. Individual extractants and the mixture of
various
organic solvents have been tested.
- Tellurium improves the
machinability of copper and stainless steel, and its addition to lead
decreases the corrosive action of sulfuric acid on lead and improves its
strength and hardness.
- Tellurium is also used
as a catalyst in the manufacture of synthetic fibers.
- Tellurium is used in
ceramics. Bismuth telluride has been used in thermoelectric devices.
About 75 percent of all the tellurium produced today is used in
alloys. Its most important alloy is a tellurium-steel alloy.
- The alkylmetal
generation technique using methyllithium can be applied to the
determination of trace levels of inorganic tellurium in aqueous
samples.
- Thin films of Tellurium
dioxide were investigated for γ-radiation dosimetry purposes. Samples
were fabricated using thin film vapour deposition technique.
- The feasibility of
growing CdZnTe by liquid phase electroepitaxy. Based on our successful
LPEE system of GaInAs, a new crucible to grow CdZnTe was
developed.
- Majority of
semiconductor crystal properties prepared by tellurium and cadmium are
known to have strong harmful influences by the presence of trace level
concentration of residual impurities since they reduce substantially
detector efficiency.
