Tellurium is a metal element with a wide range of applications across various industries. In the solar industry, it is mainly used in cadmium-telluride (CdTe) solar cells to enable efficient sunlight conversion into electricity. Thermoelectric devices also utilize Tellurium, mainly in consumer appliances like vehicle coolers and water dispensers. In electronics, Tellurium is utilized to enhance the performance of components such as RAM storage modules and rewritable optical discs.
The metallurgical sector utilizes Tellurium as an alloying agent to improve the machinability and strength of metals like copper, stainless steel, and lead, which makes it valuable for production spark plugs and radiation shielding. Additionally, Tellurium is used in chemical applications as a catalyst and vulcanizing agent in rubber production, while its compounds play roles in infrared sensors and medical instrumentation.
The market demand for Tellurium is majorly driven by its application in various downstream industries and sectors such as solar, electronics, consumer goods, optics, metallurgy, chemical, medical, etc. Its utilization in the form of CdTe-based photovoltaic cells, coupled with the increasing adoption of renewable energy, elevates the demand for Tellurium. The usage of Tellurium-based thermoelectric materials to convert waste heat into electricity boosts the demand for Tellurium in industries like automotive and power generation. Its function in semiconductors fuels its market expansion in the electronics industry. Its incorporation in steel and copper alloys contributes to its demand in the metallurgical industry. Its utilization in infrared detectors for military, space exploration, and medical imaging technologies promotes industrial Tellurium procurement.
Raw Material for Tellurium Production
According to the Tellurium production plant project report, the raw material for Tellurium production includes copper.
Production Process of Tellurium
The extensive Tellurium production cost report consists of the following major industrial production process:
- Production via electrolytic refining of copper: The production process of Tellurium initiates with the removal of copper from copper slimes. The copper slimes generated during the electrorefining of copper, undergo leaching with sulfuric acid to dissolve copper to form tellurous acid as an intermediate product. In the second stage, Tellurium is recovered through two primary methods. The first method is acid precipitation, which involves the neutralization of the tellurous acid to precipitate tellurium dioxide. The second method is electrolytic purification, where electrolysis reduces tellurium ions to metallic Tellurium.
Properties of Tellurium
Tellurium (Te) is a brittle, silvery-white metalloid with an atomic number of 52. It belongs to group 16 of the periodic table. It occurs in two allotropes: crystalline, which is metallic and lustrous, and amorphous, which appears as a brown-black powder. It has a melting point tellurium of 449.5 degrees Celsius and a boiling point of 988 degrees Celsius. It has a density of about 6.24 g/cm³. It possesses semiconductor properties, with electrical conductivity that increases slightly when exposed to light. It is chemically stable and resists oxidation in air but can dissolve in nitric acid. It has multiple oxidation states, including -2, +2, +4, and +6. It produces a greenish-blue flame when burned. It is utilized in metallurgy, solar panel production, and as a pigment in ceramics.
