Abstract:
The present application discloses a thermoelectric material, which contains CsAg5Te3 crystal material. At 700K, the thermoelectric material has an optimum dimensionless figure-of-merit ZT as high as 1.6 and a high stability, and the thermoelectric material can be recycled. The present application also discloses a method for preparing the CsAg5Te3 crystal material. The CsAg5Te3 crystal material is one-step synthesized by a high-temperature solid-state method, using a raw material containing Cs, Ag and Te, so that the high-purity product is obtained while the synthesis time is greatly shortened.
