Synthesis and Characterization of LaCr1-xSnxO3 Nanopowders (x = 0 and 0.1)

Article Preview

Abstract:

Lanthanum chromite (LaCrO3) has been considered a promissing candidate for use as interconnect materials for solid oxide fuel cells (SOFCs), due to their excellent electrical properties. In this work, LaCr1-xSnxO3 (x = 0 and 0.1) ceramic powders were prepared using the following synthesis routes: Flame spraying (FS) and microwave assisted combustion method (MCM). The powders were characterized by TGA, XRD and TEM. The TG curves showed weigh losses corresponding the dehydration of compounds as well as decomposition of secondary phases and organic matter. The XRD patterns indicated the formation of Sn doped LaCrO3 phase by FS. The crystallite sizes of samples are in the range 20-36 nm. The TEM images revealed the presence of particles with spherical shape and uniform particle size distribution.
