Sr-doped lanthanum manganite [La(Sr)MnOo] has been prepared by two different routes namely (1) solid state route and (2) citrate-gel route. The powder prepared through citrate-gel route is relatively finer than that prepared through solid state route. Sintering characteristics of the powders have been studied by measuring density and porosity. BioOg is found to be an effective sintering aid for La(Sr)MnO3 . Measurement of electrical conductivity and thermal expansion co efficient at elevated
