Home > ProductsThe CuSbS-based thermoelectric ingot for thermoelectric power generation modules, good for converting 600-1000K heat sources into electricity

       The CuSbS-based thermoelectric ingot is grown by the Thermonamic with the alloy of Cu, Sb,S and others , and our unique crystallizing processes. The CuSbS-Based thermoelectric ingot is used to fabricate the modules for power generation, good for converting 600~1000 K heat sources into electricity. The peak dimensionless figure of merit (ZT) of our p-type ingots is larger than 1.1 around 850 K, and good for waste heat recovery. Meanwhile, our ingot is featured with good mechanical strength and highly stable property, providing the key elements for producing the high performance and reliable power generation modules used for middle temperature range heat sources.
