Product Name: Bismuth Telluride Compound Semiconductor Material 4n 99.99% Tellurium Bismuth Antimony Selenium Granules Model NO.: 99.99% Carbon Content: Low Carbon Material: Bi2te3 Product Type: Pellet Trademark: Xinrong Transport Package: 1kg/Polyester Bag Specification: 2*2*3mm Origin: China Product Description MATERIAL OVERVIEWCharacteristics:Bismuth telluride is acompound of tellurium and bismuth. It is anarrow gap layered semiconductor with atrigonal unit cell. It mainly occurs in arare mineral tellurobismuthite. It's produced by sealing bismuth and tellurium metals in aquartz tube under vacuum.When alloyed with selenium or antimony, it acts as an efficient thermoelectric material suitable for portable power generation or refrigeration.Storage Conditions:Keep the reservoir sealed and stored in acool and dry place.Make sure that the workshop has good ventilation or exhaust devices.Production Processes:Vacuum melting -crystallization (crystal orientation growth) -regional melting -removal of both ends;Applications:Forming P/N section for semiconductor refrigeration, thermoelectric power generation, etc. GENERAL PROPERTIESProduct Name:Bismuth TellurideAppearance:Dark GreyMolecular Formula:Bi2Te3, BiTeMolecular Weight:800.76Melting Point:585°CFreezing Point:1130 °CConductivity Type:N-type: bismuth telluride doped Selenium.P-type: bismuth telluride doped Antimony.Density:7.642 g·cm−3CAS No.:1304-82-1EINECS No.:215-135-2Thermal Conductivity:1.2-1.6w/m.KElectrical conductivity (rou):850-1250SPECIFICATIonSN type bismuth telluride for cooling and generating electricity1Purity99.99%2Thermal conductivity (k)1.2-1.6w/m.K3Seebeck (S)205-235 uV4Electrical conductivity (rou)850-12505Figure of merit (Z)2.34-3.2×10-3.
