Used in thermoelectric devices due to its high efficiency in converting heat to electricity, especially in alloys like bismuth telluride for cooling and power generation.

Added to lead, steel, copper, and other alloys to improve machinability and corrosion resistance.

Employed in the semiconductor industry for specialized electronic components and infrared detectors.

Utilized in solar cells, particularly in cadmium telluride (CdTe) photovoltaic modules, offering low-cost, large-scale energy production.

Also found in rewritable optical media and phase-change memory devices.

In the glass and ceramics industry, used as an additive to adjust color or reduce light reflection in special lenses and materials requiring specific optical properties.

Small amounts used in catalysts for petroleum refining and rubber production.

Additionally, tellurium compounds are explored in biochemical and nanotechnology research for potential applications as antioxidants or in targeted drug delivery systems.
