Tellurium is a chemical element with the symbol Te and atomic number 52.
Tellurium is a brittle, slightly toxic, rare silver-white metalloid. Tellurium is chemically related to selenium and sulfur. It is occasionally found in its natural form as an elemental crystal.
Tellurium Applications
– Tellurium is a p-type semiconductor that exhibits greater conductivity in certain directions, depending on the arrangement of the atoms.
– Many telluride compounds exhibit photoconductivity—their conductivity increases slightly with exposure to light—making many tellurides candidates for solar applications.
– Tellurium improves the machinability of copper and stainless steel and is added to lead to increasing its strength and hardness.
– Tellurium is used as a basic ingredient in blast caps and is added to cast iron to control cooling.
– Bismuth telluride has been used in thermoelectric devices.
Tellurium is available as metals and compounds in purities ranging from 99% to 99.999% (ACS grade to ultra-high purity). Elemental or metallic forms include pellets, rods, wires, and particles for the purpose of evaporating source materials. Tellurium oxide is available in powder and compact granular form for applications such as optical coatings and thin film applications. Tellurium fluoride is another insoluble form suitable for applications where oxygen is undesirable, such as metallurgy, chemical and physical vapor deposition, and some optical coatings. Tellurium is also available in soluble forms, including chloride and nitrate. These compounds can be prepared in solution in the specified stoichiometry.
