High purity Tellurium Metal Te CAS 13494-80-9 For Semiconductor Material

Tellurium is a silver-white crystal with low resistivity and high electron mobility, making it an excellent semiconductor material. In the electronics industry, tellurium is used to manufacture field-effect transistors, solar cells and other key devices, showing its excellent performance in photoelectric conversion, energy storage and other aspects.
Tellurium is also widely used in metallurgy, chemicals and catalysts. In the metallurgical industry, adding a small amount of tellurium can significantly improve the machinability and machinability of steel. In the chemical industry, tellurium can be used as an additive to oil cracking catalysts to improve production efficiency. Tellurium compounds also have antibacterial properties and are used in medicine and skin care products.

product details

Feature

Name: Tellurium Metal, Tellurium powder

Molecular formula: Te

CAS: 13494-80-9

Molecular weight: 127.6

Description

Tellurium is a silvery white crystal of orthorhombic system. Soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, potassium hydroxide; insoluble in cold water and hot water, carbon disulfide. Tellurium burns in the air with a blue flame to form tellurium dioxide; it can react with halogen, but not with sulfur and selenium. In industry, tellurium is extracted from anode slime of electrolytic copper smelted by copper.

Used

80% of the consumption of tellurium is applied in the metallurgical industry: adding a small amount of tellurium to steel and copper alloy can improve its cutting performance and increase its hardness; in white cast iron, tellurium is used as a carbide stabilizer to make the surface strong and wear-resistant; lead containing a small amount of tellurium can improve the corrosion resistance, wear resistance and strength of materials and be used as the sheath of submarine cables; adding tellurium to lead can increase the hardness of lead To make battery plates and typography. Tellurium can be used as an additive of petroleum cracking catalyst and catalyst for glycol production. Tellurium oxide is used as a colorant for glass. High purity tellurium can be used as the alloy component of thermoelectric materials. Bismuth telluride is a good refrigeration material. Tellurium and some tellurides are semiconductor materials. Ultrapure tellurium single crystal is a new type of infrared material.
