Wuhan Xinrong New Materials Co., Ltd.  

Product Name: N P Type Bismuth Telluride Semiconductor Thermoelectric Generator Ingot 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 rod for cooling and generating electricity1Purity99.99%2Production Methodzone-melting and crystal pulling technique3Thermal conductivity (k)1.2-1.6w/m.K4Seebeck (S)210-230 α,uV/K5Electrical conductivity (rou)950-1050 α,S/cm6ZT value≥1.1@300KP type rod for cooling and generating electricity1Purity99.99%2Production MethodPowder metallurgy3Thermal conductivity (k)1.2-1.6w/m.K4Seebeck (S)205-215 α,uV/K5Electrical conductivity (rou)900-1000 α,S/cm6ZT value≥1.1@300KMore ProductsSymbol is Bi2Te3, Bismuth Telluride is widely used in Semiconductors and Thermoelectric fields.Purity is 99.99%, it can be processed into Powder, Pellets, Crystal Rods, Sputtering Targets and other shapes, Thermoelectric Cooler Peltiers are also available.General dimension of bi2te3 pellet is 1.4x1.4x1.6mm,we can produce if you need other size.General size of ntype round rod is 28mm diameter, Ptype square rod is 30mm length x30mm width x100mm height.We can also cut off the rod as per your requests.General powder particle is 100-325mesh, 10 micron powder is also available.Bismuth sputtering targets can be produced according to your requirements.Our company- Wuhan Xinrong New Materials Co.
