Manufacturer's Large Inventory Tellurium Ingot For Sale Tellurium Ingot Price
A tellurium ingot refers to a solid block or bar of the chemical element tellurium (symbol Te) that has been cast into a specific shape for storage, transportation, or further processing. Tellurium is a rare metalloid known for its unique properties.
It's worth noting that the specific applications and uses of tellurium ingots may vary depending on the industry and specific requirements. If you have any further questions or need more specific information, please let me know.
Here's some information about tellurium ingots:
Composition: Tellurium ingots are primarily composed of the chemical element tellurium. Tellurium is a brittle, silvery-white metalloid that is often found in association with other elements such as copper, gold, and silver. Commercially available tellurium ingots typically have a high level of purity, often exceeding 99.99% tellurium.
Properties: Tellurium possesses several notable properties:
Brittle and crystalline: Tellurium is a brittle material that can be easily powdered or crushed. It has a crystalline structure.
Semiconductor behavior: Tellurium is a semiconductor, meaning it can conduct electricity under certain conditions but not as effectively as metals. It exhibits properties between those of metals and nonmetals.
High electrical conductivity: Tellurium has relatively high electrical conductivity among metalloids, making it useful in certain electronic applications.
Low melting point: Tellurium has a relatively low melting point of around 450°C (842°F), which allows it to be easily melted and processed.
Unique optical properties: Tellurium exhibits unique optical properties, including the ability to transmit infrared light and a strong birefringence effect.
Applications: Tellurium ingots are used in various applications, including:
Electronics and semiconductors: Tellurium is used in the production of certain types of semiconductors, including cadmium telluride (CdTe) and bismuth telluride (Bi2Te3). These materials are used in photovoltaic solar cells, thermoelectric devices, and other electronic components.
Alloying agent: Tellurium is added to alloys, such as copper, stainless steel, and lead, to improve their machinability, strength, and corrosion resistance. For example, copper-tellurium alloys are used in electrical connectors and switchgear due to their high electrical conductivity.
Chemical applications: Tellurium compounds are used in various chemical applications, including catalysts, pigments, and as a raw material for the production of other tellurium compounds.
Optical applications: Tellurium is used in certain optical applications, including infrared optics and lenses.
Additive in glass and ceramics: Tellurium can be added to glass and ceramics to modify their properties, such as refractive index and thermal conductivity.
Safety considerations: While tellurium ingots are generally considered safe for handling, it is important to follow appropriate safety precautions, such as using personal protective equipment, when working with or processing tellurium or tellurium-containing materials. Tellurium compounds, such as tellurium dioxide, may have different safety considerations, and proper handling guidelines should be followed.
