(TU Delft Novel Aerospace Materials) Mahon, T.R. (TU Delft Novel Aerospace Materials) van der Zwaag, S. (TU Delft Novel Aerospace Materials) Groen, W.A. (TU Delft Aerospace Structures & Materials) Department Aerospace Structures & Materials Date 2019 Abstract BiFeO3 is a multiferroic material with the perovskite structure which is promising for use in sensors and transducers. Single phase production of BiFeO3 remains a challenge, however. In this study, the optimal calcination temperature to obtain close to single phase powder was determined to be 750°C. The sintering temperature of 775°C was also found to obtain high density ceramics (≈ 95 % of theoretical density). It is shown that off-stoichiometry of bismuth oxide in precursors effects the content of secondary phase. Impedance spectroscopy indicates that the content of secondary phases has a large effect on the electrical conductivity BiFeO3.
