Abstract
Thermoelectric material has attracted more attentions as a promising energy material in recent years. Research nowadays are devoted to improvement of figure-of-merit (zT=ST/ρκ). Motivated by p-type AgSbTecompound, ternary Ag—Sb—Te has been reported as an important thermoelectric system. Although ternary AgSbTecompound has been considered as a candidate for thermoelectric materials with the advantages of low thermal conductivity (κ=0.6 WKm), the relatively high electrical resistivity (ρ=7.5*10Ωcm) has limited its applications. This invention disclosed brand-new Ag—Sb—Te bulk materials with very fine microstructures that nanoscale AgTe phase precipitate uniformly in the multi-phase matrix through class I reaction, liquid=AgTe+AgSbTe+δ. Moreover, the electrical resistivity (ρ) measured by four-probe method is as low as 8.4*10(Ωcm) at room temperature, which guarantees the promise of those ternary bulk materials.
