Double A,B-doped and aid-sintered BaTiO 3 perovskite ceramics were prepared by usual ceramic techniques and firing procedure. On pellets of these potential materials, numerous measurements have been undertaken, explained and discussed in detail, namely, X-ray diffraction, IR absorption spectra, electronic absorption spectra and dc electronic conductivity versus temperature in ambient atmosphere. New information was added and supported which are benefit and helpful in modifying the crystallinity and semiconductivity of the potential perovskite ceramics.
