Bismuth Telluride powder is a high-performance raw material designed for thermoelectric materials and electronic functional ceramics. Its high purity, uniform particle size and good dispersion ensure excellent density, thermoelectric performance and stability during the preparation process.
We provide Bismuth (III) Telluride powder in a variety of particle size ranges, and can customize the particle size and packaging form according to your specific application needs. We also provide comprehensive technical and after-sales support. If you have any technical questions, please feel free to contact our team.
Purity: 99.99% to 99.999%
Precise particle size control, narrow distribution, good fluidity
Low oxygen content and good thermal stability
Particle size distribution, bulk density and packaging form can be customized on demand
Thermoelectric devices: As an excellent thermoelectric material, Bi₂Te₃ is widely used in refrigeration chips and thermoelectric power generation modules, especially in the temperature range from room temperature to 200°C.
Electronic ceramics: Used as a functional filler for materials such as capacitor ceramics and infrared detectors to improve the conductivity and thermal management performance of composite materials.
Energy recovery system: used as a high-efficiency thermoelectric conversion material in industrial waste heat utilization or automobile exhaust heat recovery.
Sensors and integrated devices: using its strong electron-thermal coupling effect to develop flexible electronics and environmental monitoring sensors.
We provide a certificate of analysis (COA), material safety data sheet (MSDS), XRD and particle size distribution report for each batch of goods. If required by customers, we also support third-party testing and can issue compliance documents to help you smoothly cope with the global market.
