Product Description:

Tellurium powder is a dark gray-to-brown, amorphous, brittle powder, a metalloid element with the symbol Te, used in various applications including solar cells, thermoelectric production, metallurgy, and rubber applications.

Product Application:
  • Cadmium Telluride (CdTe) Solar Panels: Tellurium is used in the production of CdTe solar panels. 
  • Media Layer of Rewritable Optical Discs: It is also used in the media layer of rewritable optical discs. 
  • Thermoelectric Applications: Tellurium-based thermoelectric materials are used in devices like thermocouples and thermoelectric generators for temperature measurement and waste heat conversion. 
  • Semiconductor Applications: Tellurium can be used as a precursor to prepare tellurium-based nanomaterials for semiconductor applications. 
  • Quantum Dot Solutions: Tellurium is used in quantum dot solutions for fluorometric determination of bioactive compounds. 
Product Dose:

Tellurium powder is a dark grey-to-brown, amorphous powder with metallic characteristics, a brittle, mildly toxic, and rare metalloid, used in metallurgy, electronics, and solar power applications. 

Product Note:

General Precautions:

  • Avoid contact with skin and eyes: Tellurium powder can cause irritation.
  • Do not breathe dust: Inhaling tellurium dust can cause irritation and congestion of the respiratory tract.
  • Wash thoroughly after handling: Remove any powder from skin and clothing.
  • Do not eat, drink, or smoke while handling: Avoid contamination of food or drink.
  • Keep away from food, drink, and animal feeding stuffs: Prevent accidental ingestion.
  • Keep working clothes separately: Prevent contamination of personal clothing.
  • Ensure eyewash stations and safety showers are close to the workstation location
