Experimental investigations on new materials for application as electrolyte in electrolyte supported planar Intermediate Temperature Solid Oxide Fuel Cells (lTSOFC) opcrating below SOO °C is in progress at our labor, tory. Sr and Mg doped Lanthanum gallate (LSGM) powder was prepared by glycine -nitrate combustion method. The prepared LSGM powder is relatively I,n r than that prepared through other techniques such as solid-state reaction. The measurement. comprising XRD, particle size, density, TGAIDTA were made. Thin sections of circular pellets were fabricated and annealed at different temperatures ranging b twe n 1000 and 1300 "c. The sintering behaviour of LSGM was investigated to obtain information on the densification factor, relative percentage shrinkage/expansion in volume, while annealing and the resulting apparent porosity values. Bismuth oxide is found to be an effective sintering aid in general. So the effect of bismuth oxide addition on LSGM was investigated through sintcring studies. The results obtained on LSG with and without bismuth oxide addition are discussed with respect to the requirement of an electrolyte for ITSOFC applications.
