Product Description

 

Product Description

Brief introduction

Product Name: P-type Bi0.5Sb1.5Te3

N-type Bi2Te2.7Se0.3

Purity: 99.99%, 99.999%

Appearance: Block ingot or powder

Brand: Epoch-Chem

 

Performance

The TIG-BiTe-P/N-2 thermoelectric ingot is grown with the alloy of Bi, Sb, Te, Se, special doping and our unique crystallizing processes. The Bi2Te3-based thermoelectric ingot is grown specially and optimized for making the thermoelectric modules that used for converting heat source ranging from 100ºC(373K) to 350ºC(623K) into electricity . Generally, the average figure of merit ZT of our p-type and n-type ingots over the temperature range 300K to 600K is larger than 0.7. The module made with such ingots can achieve 5% efficiency with 250ºC Delta T. Meanwhile, our ingot is featured with good mechanical strength and highly stable property, providing the key stone for producing the high performance and reliable power generation modules.
