Tellurium Ingot

Tellurium Ingots provide a stable, high-purity form of this metalloid, valued for its unique semiconducting properties, photoconductivity, and thermoelectric behavior. The ingot form ensures controlled purity and manageable handling for downstream processing, such as alloying or crystal growth. Industries including thermoelectrics, metallurgy, and electronics rely on tellurium ingots for producing thermoelectric modules, improving machinability in steel and copper alloys, and manufacturing semiconductor devices. Specific applications include bismuth telluride-based cooling systems, high-performance solar panels, and phase-change memory materials. In research, tellurium ingots are essential for exploring new chalcogenide-based semiconductors, studying topological insulators, and enhancing thermoelectric conversion efficiency. The ingot format provides a versatile starting material, supporting both experimental innovation and large-scale manufacturing in advanced technology sectors.
