MAGNETIC-SOFT HEXAFERRY MATERIAL Russian patent published in 2018 - IPC H01F1/34 C01G49/00

Abstract RU 2645762 C1

FIELD: radio engineering.

SUBSTANCE: invention relates to radio electronic engineering and concerns the creation of hexaferritic soft magnetic materials for inductive elements of the decimeter and centimeter frequency ranges. Hexaferrite material contains the following component ratio, % weight: BaO – 18.21÷18.23; CoO – 5.95÷7.45; TiO₂ – 0.10÷1.60; Fe₂O₃ – the rest.

EFFECT: invention makes it possible to obtain a magnetically soft hexaferrite material with a magnetic permeability mc_n= 10 ± 2.
