Description
: 1.:, Изобретение относитс к порошко вой металлургии, в частности к маг нитным металлокерамическим материа лам. По основному авт. св. 378699 известен ферритовый материал, соде жащий, мол%: Окись цинка1-30 Закись никел 1-49 Окись кобальта 0,05-3 Окись вольфрама 0,01-1 Окись железа Остальное. Недостатком этого материала . вл ютс относительно низкие значени начальной магнитной проницаемости /О ц и коэффициента перестройки по частоте К| . Цель изобретени - повышение на чальной магнитной проницаемости и коэффициента перестройки по частоте . Дл достижени поставленной цел ферритовый материал дополнительно держит 0,2-2,0 вес.% окиси свинца. Пример. Веретен исходна смесь Ni,j-Zn- Со - W феррита, содер жаща , мол.%: FejOa - 49 - 34,8 СоО - 1,5 W03 - 0,7 В эту смесь вводитс присадка РвО в количестве 0,2 вес.%. Изготовление ферритового материала проводите по окисной технологии . Температура предварительного обжига , спекани 1100°С. В результате получен новый феррит, у которого Ли - 45,0, Кг- 3,5. По сравнению с известным материа ..ом, имеющим / J4-38, а Кр - 3,1, /OH увеличиваетс на 18,3%, а Кг на 12,9%. Пример 2 Беретс исходна смесь Ni- Zn Со- W феррита, содержаща мол.%: FejO 49 NiO 43,7 ZnO5,0 СоО1,5 WO30,8 В нее сверх мол рного состава вводитс присадка РвО в количестве 1,0 вес.%. Изготовление Феррита проводитс по окисной технологии. Температура предварительного обжига 850с, спекани 1080. Полученный феррит: 1.:, The invention relates to powder metallurgy, in particular to magnetic cermet materials. According to the main author. St. 378699 is known ferrite material, containing mol%: Zinc oxide1-30 Nickel oxide 1-49 Cobalt oxide 0.05-3 Tungsten oxide 0.01-1 Iron oxide The rest. The disadvantage of this material. are relatively low values of the initial magnetic permeability / O c and frequency tuning factor K | . The purpose of the invention is to increase the initial magnetic permeability and frequency tuning ratio. In order to achieve the desired ferrite, the material additionally holds 0.2-2.0% by weight of lead oxide. Example. The spindle of the initial mixture of Ni, j-Zn-Co - W ferrite, containing, mol%: FejOa - 49 - 34.8 CoO - 1.5 W03 - 0.7 In this mixture, the additive PbO is added in an amount of 0.2 weight .%. Carry out the manufacture of ferrite material by oxide technology. Pre-firing temperature, sintering 1100 ° C. As a result, a new ferrite was obtained, in which Li - 45.0, Cg-3.5. Compared with the known material, having / J4-38, and Cr - 3.1, / OH increases by 18.3%, and Kg by 12.9%. Example 2 An initial mixture of Ni-Zn Co-W ferrite is taken, containing mol.%: FejO 49 NiO 43.7 ZnO5.0 CoO1.5 WO30.8 An additive of PbO is added to it in excess of molar composition in an amount of 1.0 wt.% . The manufacture of ferrite is carried out by oxide technology. Prebake temperature 850s, sintering 1080. Ferrite obtained

В нее сверх мол рного состава вводитс присадка РвО в количестве 2 вес.%. Изготовление феррита проводитс по окисной технологии. Температура предварительного обжига 750°С, спекани . Полученный 5 феррит имеет /Jy,- 16,5, kj--2. По сравнению с известным материалом, имеющим, 12, K - 1,7, Jtj увеличиваетс на 33%, а К| на 15%.A PbO additive in the amount of 2 wt.% Is introduced into it over the molar composition. The manufacture of ferrite is carried out by oxide technology. Temperature of preliminary roasting is 750 ° C, agglomeration. The resulting 5 ferrite has / Jy, - 16.5, kj - 2. In comparison with the known material having, 12, K - 1.7, Jtj increases by 33%, and K | by 15%.
