Abstract

In this paper the humidity-sensitive electrical properties of MgFe2O4thick-films are studied. Thick films were prepared by screen printingon alumina substrates and subsequent firing. Pastes for screen printing were obtained by adding an organic vehicle and Bi2O3, as a sintering aid, to MgFe2O4 powders. The microstructure of the films was varied using MgFe2O4 powders with different grain sizes and by changing the firing temperatures. The microstructure of the films was studied by scanning electron microscopy (SEM), energy dispersion spectroscopy (EDS),and Hg porosimetry. The humidity-sensitive electrical properties of thick films were tested by electrochemical impedance spectroscopy (EIS). D.C. measurements were made to test reproducibility and time response, and to study the conduction mechanism. The electrical response of the films was correlated with their microstructure and the distributionof Bi2O3 in the films.
