中文摘要 | the new compounds la2-xcaxmo1.7w0.3o9-delta (0 <= x <= 0.2) in which la3+ substituted with ca2+ were synthesized by dry-chemistry techniques based on the oxygen ionic conductor la2mo1.7w0.3o9. the new series were characterized by x-ray diffraction (xrd), raman and x-ray photoelectron spectroscopy (xps) and the electrical conductivity of samples were investigated by ac impedance spectroscopy. the lattice parameters were reduced due to the smaller atomic radius of the ca2+ compared with that of the la3+. furthermore, additional oxygen vacancies were introduced into la2mo1.7w0.3o9 lattice by substitution, and then the oxygen ionic conductivity was increased. at 550 degrees c, the conductivity increased 89.9%, that is, from 0.79 x 10(-4) s center dot cm(-1) (x=0) to 1.5 x 10(-4)s center dot cm(-1) (x=0.16, 0.2). |
