METHOD OF PRODUCTION OF ANISOTROPY FERRITES Russian patent published in 2008 - IPC B22F3/12 H01F1/34

Abstract RU 2338627 C2

FIELD: metallurgy.

SUBSTANCE: invention is related to the production of ferrites, designed for the usage in appliances with millimeter wave length (90-15 THz). BaF₂·0.5Li₂O·5.5Fe₂O₃is preliminary synthesised and then crushed dry. The product is mixed with oxides of iron substituting elements and with required before stechiometry barium fluoride and lithium oxide with further crumbling in ethyl alcohol. Then there is performed pressing in magnetic field and burning.

EFFECT: invention is characterised with significant fields of anisotropy and low dielectric losses and also with high density.
