Preparation and Conductivity of Sr_(1-x)Bi_xFeO_(3-δ)(x≤0.5) by Citrate Methods
Source abstract
Abstract
Sr1-xBixFeO3-δ (x≤0.50) series oxide ionic/electronic conductors were prepared through citrate gel precursors. The product was characterized by means of XRD, IR, TG, DTA and ac impedance techniques. Pure perovskite-type phase was formed after the gel combusted and calcined at 800℃, and had an orthorhombic structure similar to that of SrFeO3. Although the density of the product calcined at 85OC remained 97% theoretical value, an extreme conductivity of 3.6Scm-1 was found at 400℃.
