Home > ProductsHot Pressed and Extruded Bi2Te3-Base Thermoelectric Ingot (TIG-BiTe-P/N-4)

The TIG-BiTe-P/N-4 thermoelectric ingot is the one of Bi2Te3-Sb3Te3 for P and Bi2Te3-Bi2Se3 for N processed by hot press and extrusion to enhance its performance and mechanical strength. It is good in producing high performance and high reliable mini size thermoelectric modules for cooling and heating applications, specially used in telecom or photonics. Generally, the figure of merit, the dimensionless ZT of our p-type is larger than 1.1 and n-type ingots is larger than 1.0 at 300 K , and the excellent mechanical strength is good for the modules that require thin and tiny size dices, providing the key stone for producing the high performance and reliable Peltier cooling modules. It is ideal materials for making micro size modules.
