Ferrite Magnetic Powder Material Forming Process

I-Ferrite yintsimbi ye-oxide ye-alloy enentsimbi.Ngokubhekiselele kumbane, ii-ferrites zine-resistivity enkulu kakhulu kune-elemental metal alloy compulments, kwaye zineempawu ze-dielectric.Amandla ombane kwiyunithi nganye umthamo we-ferrite uphantsi Xa i-frequency ephezulu iqokelelwe, amandla ombane kwiyunithi nganye umthamo we-ferrite uphantsi.(Bs) kwakhona amandla aphantsi (kuphela i-1/3 ~ 1/5 yentsimbi ecocekileyo), ekhawulela uluhlu lokukhetha kunye nokunciphisa uluhlu olubanzi lweemfuno, kwaye lunokusetyenziswa ngokubanzi kwizicelo eziqinileyo eziqhelekileyo zangoku kwiinkalo ezahlukeneyo.

I-Ferrite ifakwe kwi-iron oxides kunye nezinye izithako.Ngokubanzi, inokwahlulwa ibe ziintlobo ezintathu: i-ferrite esisigxina, i-ferrite ethambileyo kunye ne-gyromagnetic ferrite.

Imagnethi esisigxina ye-ferrite ikwabizwa ngokuba yi-ferrite magnet, eyimagnethi encinci emnyama esiqhele ukuyibona.Izinto zayo eziphambili ziyi-iron oxide, i-barium carbonate okanye i-strontium carbonate.Emva kwemagneti, amandla ombane oshiyekileyo aphezulu kakhulu, kwaye indawo eshiyekileyo yamagnetic inokugcinwa ixesha elide.Idla ngokusetyenziswa njengesixhobo semagnethi esisigxina.Umzekelo: iimagnethi zesithethi.

I-ferrite ethambileyo ilungiswa kwaye ifakwe i-ferric oxide kunye nenye okanye ezinye ii-oxide zetsimbi ezininzi (umzekelo: i-nickel oxide, i-zinc oxide, i-manganese oxide, i-magnesium oxide, i-barium oxide, i-strontium oxide, njl.).Ibizwa ngokuba yimagnethi ethambileyo ngenxa yokuba xa imagnethi yamandla ithi shwaka, kukho intsalela yemagnethi yemagnethi.Ngokuqhelekileyo isetyenziswa njengekhoyili yokukrwitsha, okanye ingundoqo ye-transformer frequency intermediate.Oku kwahluke ngokupheleleyo kwi-ferrite esisigxina.

I-Gyromagnetic ferrite ibhekisa kwisixhobo se-ferrite esineempawu ze-gyromagnetic.I-gyromagnetism yezixhobo zozibuthe ibhekisa kwinto yokuba iplanethi yepolarization yeplanethi-ipolarized electromagnetic wave isasazeke kwicala elithile ngaphakathi kwesixhobo phantsi kwentshukumo yemimandla yombane ejikelezayo ye-DC kunye nemimandla yemagnethi yombane.I-Gyromagnetic ferrite isetyenziswe ngokubanzi kwintsimi yonxibelelwano lwe-microwave.Ngokohlobo lwekristale, i-gyromagnetic ferrite inokwahlulwa ibe luhlobo lwe-spinel, uhlobo lwegarnet kunye nohlobo lwe-magnetoplumbite (uhlobo lwe-hexagonal) ferrite.

Imathiriyeli yemagnethi isetyenziswa kakhulu kwaye ingasetyenziswa kwi-electro-acoustic, unxibelelwano, iimitha zombane, iimotor, kunye namalungu enkumbulo, amacandelo e-microwave, njl. njl. iikhomputha, kunye namakhadi kazibuthe eevawutsha zokukhwela umkhweli kunye nokuhlawulwa kwentlawulo.Oku kulandelayo kugxininise kwizinto ezisetyenziswayo kwi-tape magnetic kunye nomgaqo wesenzo.
