METHOD OF PRODUCING SINGLE-PHASE BISMUTH FERRITE NANOPOWDER Russian patent published in 2015 - IPC B22F9/00 B82B3/00 C04B35/45 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing bismuth ferrite-based nanopowder for producing magnetoelectric materials - multiferroic materials and electronic components, which can be widely used in microelectronics, particularly spin electronics (spintronics), sensor and microwave engineering, information recording, reading and storage devices, etc. The objective of the present invention is to produce pure homogeneously dispersed nanocrystalline bismuth ferrite-based powder with strict stoichiometry in a single step for producing electronic materials and components. The advantages of the present method are: directly obtaining single-phase bismuth ferrite; purity and homogeneity; low synthesis temperature; rapidness owing to obtaining the product in a single synthesis step.

EFFECT: invention increases efficiency and reduces power consumption when producing pure homogeneously dispersed nanocrystalline bismuth ferrite-based powder with strict stoichiometry by heating, at different rates, a glycerine-containing solution of nitrates of corresponding metals with different saturation.
