Description :
Cd1-xLaxFe03 crystallites were prepared by sol-gel citrate method.A stoichiometric
mixture of Lanthanum nitrate and Ferric nitrate with citric acid monohydrate and
ethylene glycol was used.The solution of Cadmium nitrate was used as dopant in
varying wt.% of Cadmium nitrate.Particle size was determined by XRD using Scherrer’s
equation.XRD analysis confirmed the formation ofnanosizedLaFe03material.The particle
size was found to be ~ 27nm.Conductivity measurements shows the Cadmium
doped(15%)LaFeO3shows highest conductivity at 7000C.Gas Sensitivity measurement
shows the 10wt% Cd doped LaFeO3 adsorbed maximum H2S gas at 2500C.
