Tellurium powder is a kind of quasi-metallic powder material with grey appearance, density of 6.25g/cm³, melting point of 450°C, boiling point of 1390°C, chemically active, with a certain degree of toxicity, and has a wide range of applications in semiconductors, metallurgy, chemical industry and other fields.
VIMATERIAL offers high-purity tellurium powder, available in various sizes to meet your needs. Contact us for more information.
Chemical formula: Te
Appearance: usually grey-black or dark grey powder.
Density: about 6.24 g/cm3.
Melting point: 450°C
Boiling point: 1390°C
Electrical conductivity: As a quasi-metal, it has good electrical conductivity, but it is weaker than typical metals.
Thermal conductivity: The thermal conductivity is about 2.35 W/m/K.
Chemical stability: Tellurium metal is relatively stable at room temperature, but when heated and melted in air it produces white fumes of tellurium oxide.
Semiconductor Field: Tellurium is used to prepare materials like bismuth telluride for thermoelectric power generation and refrigeration, converting heat into electricity in applications such as waste heat recovery and space probes. It is also used in infrared detectors and solar cells to improve sensitivity and photoelectric conversion efficiency.
Chemical Industry: Used as a catalyst or catalyst additive in processes like petroleum cracking and coal hydrogenation to improve efficiency and save energy. It also acts as a dispersant in rubber to enhance strength, elasticity, and durability, and can prevent oxidation in certain materials to extend their lifespan.
Metallurgical Industry: Tellurium powder is used in steel desulphurisation and deoxidation to improve quality, and as an alloy additive to increase strength, hardness, wear resistance, and corrosion resistance in steels and high-alloy materials.
Other Fields: Used as a coloring agent in ceramics and glass for decorative effects, in casting paints to improve surface quality, and for printing lead lettering on battery plates.
Tellurium powder is typically packed in double-layer moisture-proof sealed bags or aluminum foil bags, placed in sturdy cartons or drums, with cushioning materials inside to prevent moisture, oxidation, or mechanical damage during transport, ensuring purity and integrity of the powder.
Store in a cool, dry, and well-ventilated environment, away from heat, moisture, and corrosive substances. Keep the package tightly sealed and avoid prolonged exposure to air to maintain chemical stability and performance.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
