Abstract： |
The invention discloses a composite CoSb3 based heat electric material and making method of nanometer SiC particle in the new-typed energy technical domain, which comprises the following steps: allocating Co, Sb and doped element according to chemical formula as Co1-xMxSb3+ySiC; balling; obtaining the microfine powder evenly; sintering to synthesize block CoSb3 based thermoelectric material of nanometer SiC particle under 250-600 deg. c through discharge plasma; utilizing dispersed SiC to inhibit the growth of CoSb3 crystal. |
