Abstract:
Double perovskite Sr2FeTiO6- (SFT) has been developed by substitution of Nb and V
on Ti site to produce Sr2FeTi1-x(Nb, V)xO6- (x = 0.05 - 0.5) and tested for conductivity. The
materials were synthesized by a conventional solid-state reaction with calcination and
sintering temperatures of 1050 oC for 12 hours and 1250 oC for 12 hours, respectively. Phase
identification carried out using x-ray powder diffractometer indicated the materials consist of
double-perovskite structure and impurity phase. The intensity of impurity phase was
increased with the increasing of Nb and V content. The electrical conductivity determined by
a 4-point probe DC technique in air indicated among the oxide examined,
Sr2FeTi0.95Nb0.05O6- and Sr2FeTi0.95V0.05O6- show the increase in conductivity with
maximum conductivities of 2.4 S cm-1 and 3.9 S cm-1 at 700 oC respectively which is a result
of the electronic compensation of Nb and V at the B-site cation. Moreover, the application of
Sr2FeTi0.95(Nb, V)0.05O6- as electrode material for single - cell SOFC will be investigated.
