FERRITE MATERIAL Russian patent published in 2015 - IPC H01F1/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to ferrite materials with low dielectric losses and high residual magnetic induction to be used in microwave systems, for example, antenna elements of phased arrays. Ferrite material is produced from the mix of powders of Fe₂O₃, Li₂CO₃, Bi₂O₃, ZnO, NiO, Na₂CO₃, MnCO₃ at the following ratio of components, wt %: iron oxide 71.38±0.1, lithium carbonate 4.17±0.05, sodium carbonate 0.79±0.03, zinc oxide 10.39±0.1, nickel oxide 3.18±0.05, manganese carbonate 9.79±0.1, bismuth oxide 0.3±0.03.

EFFECT: reduced dielectric losses and higher residual magnetic induction, higher strength ease of machining.
