摘要:Bi2O3/YSZ (Y2O3-stabilized ZrO2) composite powders for solid electrolytes application were synthesized by chemical co-precipitation method. The effects of raw material ratios and temperatures on the properties of the composite powders were studied. The morphology, crystal structure and phase composition of the composite powders were characterized by means of field emission scanning electron microscope (FESEM), energy dispersive spectrometer (EDS) and X-ray diffraction (XRD). The results showed that the Bi2O3/YSZ composite powders could be fabricated by chemical process, and the composite powders with different shapes were prepared when the ratio of raw materials or temperature changed. The one-dimensional rod-like Bi2O3 particles were obtained when the content of Bi2O3 was above 10 mol% or the heating mechanism was changed. And the growth mechanism of Bi2O3 in the synthesis process was studied. The oriented attachment with interaction of Ostwald ripening was the possible growth mechanism.
