Chemical stability and electrical properties of Nb doped BaCe0.9Y0.1O3-b
Abstract
BaCe0.9-xNbxY0.1O3-δ (where x = 0.01, 0.03 and 0.05) fine powders were synthesized
by auto-combustion reaction to investigate the influence of Nb concentration on
chemical stability and electrical properties of BaCe0.9Y0.1O3-δ. The dense electrolyte
pellets were formed from powders after being uniaxially pressed and sintered at 1600ºC
for 5h. Chemical stability in a CO2 atmosphere at 750ºC was determined by X-ray
powder diffraction. Conductivities of the sintered samples have been measured within
the temperature range of 500-750ºC in different atmospheres (dry and wet argon, wet
hydrogen). The highest conductivities were obtained at 750ºC in wet hydrogen reaching
the value of 3,26.10-3Sm.cm-1.
