Anisotropic lattice expansion determined during flash sintering of BiFeO3 by in-situ energy-dispersive X-ray diffraction
(Elsevier, 2019)
BiFeO3 has a Curie temperature (TC) of 825 °C, making it difficult to sinter using conventional methods while maintaining the purity of the material, as unavoidably secondary phases appear at temperatures above Tc. Flash ...

Flash sintering of highly insulating nanostructured phase-pure BiFeO3
(American Ceramic Society, 2017)
We show that BiFeO, that is electrically homogeneous, is a good insulator, and has a low dielectric constant (the properties desired in its applications), can be produced by flash sintering, which is nominally difficult ...

Preparation of ytterbium substituted BiFeO3 multiferroics by mechanical activation
(Elsevier, 2017)
Samples in the system Bi1−xYbxFeO3 (0.02 ≤ × ≤ 0.07) have for the first time been prepared by mechanical activation followed by sintering. XRD and DSC measurements show that the solubility limit of ytterbium in the R3c ...

Preparation of phase pure, dense fine grained ceramics by conventional and spark plasma sintering of La-substituted BiFeO3 nanoparticles
(Elsevier, 2015)
High density ceramics of the system Bi1−xLaxFeO3, 0 ≤ x ≤ 0.15, have been prepared starting from nanoparticles obtained by mechanosynthesis. The ceramics have been sintered conventionally at 850 °C and by spark plasma ...
