RADIO ABSORBING FERRITE Russian patent published in 2021 - IPC H01F1/34 C22C29/12 C04B35/26

Abstract RU 2759859 C1

FIELD: radio-absorbing ferrites technology.

SUBSTANCE: invention relates to the technology of radio-absorbing ferrites. It can be used in the production of anechoic chambers, ensuring the elimination of radio waves reflection from the chamber walls. The radio-absorbing ferrite contains, mol.%: lithium oxide 1.5-3.5, zinc oxide 5.0-12.0, manganese oxide 3.5-8.5, iron oxide - the rest.

EFFECT: increase in radio-absorbing properties is provided in the frequency range from 0.8000 MHz to 3.2000 MHz.
