Tellurium (Te) Ingot Applications

  • Used in the production of photovoltaic cells, solar panels, and other optoelectronic devices due to tellurium's excellent optoelectronic properties.
  • Used as semiconductor materials for the manufacturing of devices such as infrared detectors, lasers, and optocouplers.
  • Be alloyed with lead to form lead-tellurium alloys, which are applied in nuclear industries for detectors and radiation shielding materials.

Tellurium (Te) Ingot Packing

Tellurium (Te) Ingot is carefully packaged in carton boxes with foam protection to minimize damage during storage and transportation and to preserve the quality of our products in their original condition. The vacuum packing is 1kg/bag, 25kg/barrel, or based on specific requirements.
