Abstract

Nanosized, single-phase perovskite-type LaFeO3 powders are prepared by the thermal decomposition at 600 degrees C of a hexacyanocomplex, La[Fe(CN)(6)].5H(2)O. The formation of LaFeO3 and its microstructural evolution with the temperature have been studied by simultaneous thermogravimetric and differential thermal analysis (TG/DTA), x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). LaFeO3 is formed by the decomposition of the complex with a peculiar morphology, consisting of nanosized particles in soft agglomerates with the same size and shape of the complex grains. The nanosized particles are free of pores, making the powders suitable for application in thick film fabrication, after disruption of the agglomerates, for their use as active elements for gas sensors. Preliminary experiences are encouraging the use of this sensor for NO2 detectionin the real environment. (C) 1997 Elsevier Science S.A.
