N2 - In the present study, 0, 0.2, and 0.4wt% MnO2 doped BaTi 2O5 ceramics were fabricated by three different routes, i.e., sol-gel deriving powders and spark plasma sintering (SPS) sintering, solid state calcining and SPS sintering, sol-gel deriving powders and two times sintering. Only through the sol-gel technique and conventional sintering route, Mn could substitute for Ti as the acceptor doping and consequently caused the sharp drop of the Curie temperature as well as the enhanced dielectric constant and restricted ferroelectricity. Besides, the 0.2wt% MnO2 doped BaTi2O5 ceramics fabricated by sol-gel deriving powders and SPS sintering exhibited the most superior dielectric and ferroelectric properties.
