中文摘要 | the ce0.8nd0.2o1.9 and doped with moo3 were prepared through modified sol-gel method. it is systematically discussed that the effects of moo3 doping on the structures and conductivity. the structures of the samples were characterized by means of x-ray diffraction (xrd), and field-emission scanning electron microscopy (fesem). the ionic conductivity was systematically studied in air using an ac impedance spectroscopy. the results showed that the moo3 can form a thin amorphous film around particles, which reduces the interparticle friction, and increases the contact area of particles in a compact solid. and this promotes mass diffusivity of the matrix, thus enhancing the further increase in densification and decrease in the volume fraction of grain boundary. the total and grain boundary conductivity increases due to the decreasing of the grain boundary resistance. it shows that the solution ce0.8nd0.2o1.9 doped with moo3 was detected to be with the higher conductivity (sigma(t)=6.42x10(-3) s.cm(-1), sigma(gb)=2.03x10(-2) s.cm(-1) at 600 degrees c), which is more or less one point five times of sigma(t) and four times of sigma(gb) for sample without moo3 doping respectively. moo3 is the pet-feet sintering aids of the ndc system. |
