Sb-doped SnP2O7 were prepared and characterised. with XRD, FTIR, SEM and EIS. The preparation parameters were optimised taking into consideration the influence of H3PO4 content in the reactants and PmOn impurities. Conductivities Of SnP2O7 with different Sb doping levels were studied from 100 to 300 degrees C in un-humidified air. The conductivity of 20 mol-% Sb-doped SnP2O7 was greater than 0.1 S cm(-1) at 300 degrees C. The effect of heat treatment was identified as an important factor in the preparation of the proton conductors. The time dependence of the conductivity demonstrated Sb-doped SnP2O7 as a promising intermediate temperature solid proton conductor.
