Multiferroic bismuth ferrite (BiFeO3) powders were synthesized using hydroevaporation (HE) and sonochemically assisted hydrothermal (HT) method to
investigate how different synthesis methods affect the properties of the powders and
sintered samples. The structural and microstructural analyses revealed that all the
samples contain secondary phases, Bi25FeO40 and Bi2Fe4O9, but their contribution
depends on conditions of thermal treatment (calcination and sintering). The densest
(88% and 95 % of theoretical density for HE and HT sample, respectively) ceramics
were obtained after pressing of powders at 9 t/cm2
followed by sintering at 820 °C
for 2 h. Ferroelectric properties of sintered samples were correlated with grain size
and density, while the presence of charge defects indicated distortion of crystal
lattice. Magnetic measurements of M(H) for both sintered samples showed small
deviation from linearity. The sample sintered from HT powder exhibited greater
remnant electric ...polarization as well as greater value of magnetization as a function
of temperature. Also, after cooling in magnetic field this sample indicated the
asymmetric magnetic hysteresis loop (exchange bias effect). Although both samples
showed weak electric (Pr ≤ 1 μC/cm2
) and magnetic polarization (M ≤ 0.01 emu/g)
at room temperature, ceramics obtained from HT powder was overall superior with
respect to multiferroic properties.
