Abstract

Phase-pure (La0.9Sr0.1)(Ga0.7Fe0.3)O3 − y and (Sr1.8La0.2)(GaFe)O5.1 powders with the perovskite and brownmillerite structures have been prepared from salt solutions by sol-gel processing at temperatures from 570 to 870 K. Ceramic coatings up to 100 μm in thickness have been produced by applying suspensions of the sol-gel powders to various substrates. The structure and microstructure of the ceramic coatings have been studied by x-ray diffraction and scanning electron microscopy.
