I-Ferrite Magnetic Powder Material Forming Process

I-Ferrite iyi-oxide yensimbi ye-alloy eyinsimbi.Mayelana nogesi, ama-ferrite ane-resistivity enkulu kakhulu kune-elemental metal alloy compositions, futhi anezakhiwo ze-dielectric.Amandla kazibuthe ngeyunithi ngayinye yevolumu ye-ferrite iphansi Uma imvamisa ephezulu iqoqwe, amandla kazibuthe ngeyunithi ngayinye yevolumu ye-ferrite iphansi.(Bs) futhi inamandla aphansi (kuphela i-1/3 ~ 1/5 yensimbi ehlanzekile), ekhawulela ububanzi bezinketho futhi ikhawulela ububanzi obubanzi bezidingo, futhi ingasetshenziswa kabanzi ekusetshenzisweni kwamanje okuqinile okujwayelekile emikhakheni ehlukene.

I-Ferrite igaywa nge-iron oxides nezinye izithako.Ngokuvamile, ingahlukaniswa ngezinhlobo ezintathu: i-ferrite ehlala njalo, i-ferrite ethambile kanye ne-gyromagnetic ferrite.

I-Permanent magnet ferrite ibizwa nangokuthi i-ferrite magnet, okuwuzibuthe omncane omnyama esivame ukuwubona.Imikhiqizo yayo eyinhloko i-iron oxide, i-barium carbonate noma i-strontium carbonate.Ngemuva kwe-magnetization, amandla ensimu kazibuthe esele aphezulu kakhulu, futhi insimu yamagnetic esele ingagcinwa isikhathi eside.Ivamise ukusetshenziswa njengezinto zikazibuthe ezihlala njalo.Isibonelo: omazibuthe besipikha.

I-ferrite ethambile ilungiswa futhi ifakwe i-ferric oxide kanye ne-oxide eyodwa noma amaningana ensimbi (isibonelo: i-nickel oxide, i-zinc oxide, i-manganese oxide, i-magnesium oxide, i-barium oxide, i-strontium oxide, njll.).Ibizwa ngokuthi zikazibuthe ezithambile ngoba lapho insimu kazibuthe edonsayo inyamalala, kuba nensalela yamandla kazibuthe.Ivamise ukusetshenziswa njengekhoyili yokuminyanisa, noma umnyombo we-intermediate frequency transformer.Lokhu kuhluke ngokuphelele ku-ferrite ehlala njalo.

I-Gyromagnetic ferrite ibhekisela kumpahla ye-ferrite enezici ze-gyromagnetic.I-gyromagnetism yezinto kazibuthe ibhekisela kwinto yokuthi indiza ye-polarization yendiza-polarized electromagnetic wave isakazeka ohlangothini oluthile ngaphakathi kwento ngaphansi kwesenzo sezinkambu kazibuthe ze-DC ezimbili ezihambisanayo kanye nezindawo kazibuthe ze-electromagnetic wave.I-Gyromagnetic ferrite isetshenziswe kabanzi emkhakheni wokuxhumana nge-microwave.Ngokusho kohlobo lwekristalu, i-gyromagnetic ferrite ingahlukaniswa ngohlobo lwe-spinel, uhlobo lwe-garnet kanye nohlobo lwe-magnetoplumbite (uhlobo lwe-hexagonal) ferrite.

Izinto zikamagnetic zisetshenziswa kakhulu futhi zingasetshenziswa kuma-electro-acoustic, ezokuxhumana, kumamitha kagesi, amamotho, kanye nezingxenye zememori, izingxenye ze-microwave, njll. Ingasetshenziswa ukuqopha ulimi, umculo, kanye namakhasethi olwazi lwezithombe, imishini yokugcina kazibuthe. amakhompyutha, namakhadi kazibuthe amavawusha okugibela abagibeli kanye nokukhokhiswa kwemali yokugibela.Okulandelayo kugxile ezintweni kazibuthe ezisetshenziswa ku-tape kazibuthe kanye nomgomo wesenzo.
