Изобретение относитс  к ферритовым материалам , нредназначенным дл  работы в миллиметровом диапазоне длин волн.This invention relates to ferrite materials intended to operate in the millimeter wavelength range.

11звестен ферритовый материал, содержащий окислы железа, бари , кобальта, , сканди  и титана.11, a ferrite material containing oxides of iron, barium, cobalt, scandium and titanium is known.

Цель изобретени  - уменьшить поле анизотропии .The purpose of the invention is to reduce the anisotropy field.

Это достигаетс  тем, что в ферритовый материал введена окнсь никел  при следующем cooiHoincMinii компонентов, вес. %:This is achieved by inserting nickel window into the ferrite material at the next cooiHoincMinii components, weight. %:

Окис) барн 9,7-10,2Oxide) Barn 9.7-10.2

Окнсь никел 9,4-9,9Windows nickel 9.4-9.9

Окись сканди 0,4-18,3Scandium oxide 0.4-18.3

Г1|)ед.,1пгаел11) ферритовыГ| .материал имеет ноле анизотропии 12,7-0,7 кэ.G1 |) units, 1pd) 11) ferrites | The material has zero anisotropy of 12.7-0.7 ka.

Феррнтовый материал, содержащий 9,77% окиси бари , 9,52% окисн никел , 4,40% окиси сканди , остальное окись железа, нолучают переменгиванием исходных компонентов и обжигом полученной смеси при 1200-1250°С.The ferrite material containing 9.77% barium oxide, 9.52% nickel oxide, 4.40% scandium oxide, the rest is iron oxide, is obtained by reversing the initial components and calcining the mixture obtained at 1200-1250 ° С.

Обожженный порошок подвергают мокрому помолу и прессуют в магнитном поле. После сущкп детали обжигают при 1240-1300°С.The calcined powder is subjected to wet grinding and pressed in a magnetic field. After all parts burned at 1240-1300 ° C.

Полученный фер1ритовый материал имеет поле апизотропии 5,2 кэ и намагниченность насыщени  260 гс при нлотности 4,7 г/см.The obtained ferrite material has an apisotropy field of 5.2 ke and a saturation magnetization of 260 g / s at a density of 4.7 g / cm.

Применение предлагаемого ферритового материала в вентил х миллиметрового диапазона позвол ет создать нрибор в диапазоне частот 22-40 ггц.The use of the proposed ferrite material in millimeter-range valves allows creating an instrument in the frequency range 22-40 GHz.
