| Abstract: | Samples of Bi0.5-xLaxSr0.5Co Oy ceramics havC been prepared by melting method and common solid--state reaction. The pyrolytic decomposition mechanism, phase composition and microstructure of the samples are investigated by TG/DSC, XRD and SEM. The results show that ceramics samples fabricated by melting method are of high relative density, perfect fine--grains, plate--shaped structure and orientated grains. The preparation technologies can influence the microstructure and thermoelectric properties of ceramics samples greatly. |
