%X NiO-YSZ nanocomposite powders were successfully prepared by ultrasonic co-precipitation method,with ZrOCl2·8H2O,Y(NO3)3·6H2O,NiSO4·7H2O as raw materials.The morphology,crystal structure and reducing process of the products were studied by TPR,XRD and TEM etc.The conductivity of Ni-YSZ with different Ni content was determined through the Four-terminal electrode method.The results showed that the products were small diameter,narrow size distributions,and the mass fraction of 50%Ni was more appropriate.The electrochemical impedance spectra of Ni-YSZ prepared by ultrasonic co-precipitation method was compared with Ni-YSZ prepared by mechanical mixing method,it showed that the former had smaller resistance than the latter.
