Abstract

E~vri.;:r; the recent years, much interest has been focused on the perovskite-ferrites type structure, because of their great importance in indnstrial application as anode materials used in solution electrolysis. Ferrite electrode has low electrical resistivity, high corrosion resistance and high mechanical strength. Ferrites were chosen to possess perovskite structure extensively used in certain electrical devices, magnetic heads and in electronic circuits, since the;. exh.ihits fluorescence, ferromagnetic and ferroelectric properties. The substituted La-ferrite-titanate ceramic bodies were czcurateiy 2repared with sclid ceramic and firing technique. The prepared La A(Fe Ti )O perovskite ferrite 1: 0.7 0.3 3-y hfidios (where A=Sr, Ra; 0 . 0 5 x 5 1.0) were subjected to a L .- -
czrefui course cf sintering technique to enhance the doping
mechanism and to modify the properties of the final obtained
refractcry b~dies.
