MEchanochEMIcal SynthESIS of BISMuth fErrItE, preparation of phase-pure bismuth ferrite is reported to be difficult. During synthesis, the kinetics of formation always leads to a mixture of BiFeO 3 as a major phase along with the impurity phases such as Bi 2 Fe 4 O 9 and Bi 25 FeO 39. Researchers have suggested different reasons for the appearance of the secondary phases.

Mechanochemical synthesis of zinc ferrite from zinc
Abstract Mechanochemical synthesis of zinc ferrite (ZnFe 2 O 4 ) from a powder mixture of zinc oxide (ZnO) and hematite (α-Fe 2 O 3 ) by room temperature grinding using a planetary ball mill was investigated. The grinding enables us to obtain the amorphous mixture of the starting materials.

Bismuth ferrite (BiFeO3), which was prepared by a two-step solid-phase synthesis, exhibited catalytic activity in the photodegradation of bromophenol blue under the action of hydrogen peroxide. Mechanical preactivation of BiFeO3 in an atmosphere of argon led to an increase in the photocatalytic activity due to an increase in the specific surface area.Mechanochemical synthesis and characterisation of,Bismuth niobate solid solutions, BixNbOδ(2.5≤x≤6), have been prepared using a mechanochemical method.
