The dielectric properties of BaTiO3 based ceramics co-doped with Bi/Mn
چکیده انگلیسی

BaTiO3 based ceramics (with some additives such as ZrO2, SnO2, etc.) were prepared by solid state reaction. Mn2+ or Mn3+ as an acceptor substituting for Ti4+ in B site and Bi3+ as a donor substituting for Ba2+ in A site were co-doped in BaTiO3 based ceramics. The dielectric properties of BaTiO3 based ceramics co-doped with Bi/Mn were investigated. The results show that the dielectric properties of BaTiO3 based ceramics co-doped with Bi/Mn are affected by the mole ratio of donor and acceptor (Bi/Mn). When the mole ratio of donor and acceptor is high, dielectric dispersion behavior was observed and the dielectric constant decrease and remnant polarization, coercive field and piezoelectric constant will varied. When Bi varied from 1.0% to 2.0 mol% (Mn = 0.8 mol%), remnant polarization from 10.35 to 2.25 μC/cm2, coercive field from 4 to 2.75 kV/cm, and piezoelectric constant d33 from 137 to 36 pC/N respectively.
