Whether you need custom dimensions or consistent long-term supply, we focus on delivering tellurium products that fit your goals, not just another standard material listing.

Features of Custom 99.9999% Pure Te Pieces

Purity Grade: 99.9999% corresponds to the 6N grade, falling within the category of high-purity tellurium; higher grades such as 7N (99.99999%) are also available, with total impurity content controllable below 0.1 ppm.

Physical Properties: Tellurium is a silvery-white, metallic-lustered metalloid solid with a density of approximately 6.25 g/cm³, a melting point of 452°C, and a boiling point of 1390°C; it is relatively brittle.

Chemical Stability: It is insoluble in water and carbon disulfide but soluble in sulfuric acid, nitric acid, aqua regia, and alkaline solutions; it oxidizes slowly in air at room temperature and produces toxic tellurium dioxide fumes when burned at high temperatures.

Form Advantage: Supplied in piece form, facilitating subsequent processing into sputtering targets, evaporation materials, or alloy components; sizes and packaging can be customized upon request.

Safety Precautions: Tellurium powder and vapors are toxic; inhaling dust may cause symptoms such as nausea, vomiting, and a garlic-like odor on the breath, so protective measures are required during handling. Mixtures of tellurium powder and air are explosive; storage requires a cool, well-ventilated area away from oxidizing agents.

Applications of Custom 99.9999% Pure Te Pieces

Semiconductor Manufacturing: High-purity tellurium serves as a fundamental raw material for producing II-VI compound semiconductors (such as cadmium telluride and tin telluride), which are used in thin-film solar cells, infrared detectors, and phase-change memory devices.

Thermoelectric Materials: Bismuth telluride (Bi₂Te₃) is currently one of the most mature thermoelectric materials; high-purity tellurium serves as a core raw material for it. It is used in micro-thermoelectric coolers (Micro-TECs), which are widely applied for precise temperature control in AI optical modules.

Infrared Optics: Ultra-pure tellurium single crystals are advanced infrared materials used to fabricate infrared detectors and laser components; material purity directly impacts device sensitivity and stability.

Scientific Research and High-End Manufacturing: High-purity tellurium is also utilized in cutting-edge research—such as quantum communication, energy storage, and catalysis—and serves as a specialized functional material in high-end sectors like aerospace and the nuclear industry.
