Aikace-aikace na ferrite magnet abu

Ferrite magnet abu ne mai ferromagnetic karfe oxide. A cikin sharuddan lantarki Properties, da resistivity na ferrite ne da yawa fiye da na ƙarfe da kayan maganadisu na alloy, kuma yana da mafi girma dielectric ayyuka. Ayyukan maganadisu na ferrite shima yana nuna girma Magnetic permeability a high mita. Saboda haka, ferrite magnet abu ya zama kayan magnetic na yau da kullun wanda ba ƙarfe ba don babban mita da rauni iyaka na yanzu. Saboda ƙarancin ƙarfin maganadisu da ke riƙe kowace juzu'in naúrar ferrite da ƙananan jikewa magnetization, ferrite suna iyakance a ciki aikace-aikacen da ke buƙatar babban ƙarfin ƙarfin maganadisu a ƙananan mitar da girma matsalolin wutar lantarki.

Ferrite maganadiso ana kerarre ta foda karfen karfe. An rarraba su zuwa nau'i biyu: barium (Ba) da strontium (Sr), kuma sun kasu kashi biyu: anisotropic da isotropic. Yana da a Magnet na dindindin wanda ba shi da sauƙin lalata kuma ba sauƙin lalata ba. The abu, tare da matsakaicin zafin aiki na digiri Celsius 250, shine in mun gwada da wuya da gaggautsa. Ana iya yanke shi da sarrafa shi da kayan aiki irin su yashi lu'u-lu'u, kuma ana iya kafa shi a lokaci ɗaya tare da ƙirar da aka sarrafa ta gami. Irin waɗannan samfuran ana amfani da su sosai a cikin injinan maganadisu na dindindin (Motor) da masu magana (Speaker) da sauran fagage. Yafi dacewa ga sadarwa, watsa shirye-shirye, lissafi, sarrafawa ta atomatik, kewayawa radar, kewaya sararin samaniya, tauraron dan adam sadarwa, ma'aunin kayan aiki, bugu, maganin gurɓataccen ruwa, biomedicine, sufuri mai sauri, da dai sauransu.

Ferrite na cikin rukunin semiconductors a cikin kayan lantarki, don haka ana kiransa magnetic semiconductor. Magnetite ne mai sauki ferrite.

1. ferrites na dindindin sun haɗa da barium ferrite (BaO.6Fe2O3) da kuma strontium ferrite (SrO.6Fe2O3). High resistivity, yana cikin nau'in semiconductor, don haka yawan amfanin yau da kullun kaɗan ne, karfin tilastawa yana da girma, ana iya amfani dashi yadda ya kamata a cikin da'irar tazarar iska, wanda ya keɓanta ga ƙananan janareta da maɗaukaki na dindindin. Ba ya ƙunshi karafa masu daraja irin su nickel da cobalt. A albarkatun kasa ne m, da tsari ba rikitarwa ba ne, kuma farashin yana da ƙasa. Za a iya maye gurbin AlNiCo na dindindin maganadisu. Babban kwatankwacin samfurin makamashin maganadisu yana da ƙasa, don haka ya fi girma karfe maganadiso karkashin babba Magnetic yanayi makamashi yanayi. Yanayin zafinsa kwanciyar hankali ba shi da kyau, yanayinsa yana da karye kuma ba zai iya jurewa ba tasiri da jin dadi. Bai dace da kayan aunawa da kayan maganadisu ba tare da tsauraran buƙatu. Samfuran na dindindin magnet ferrite sune galibi jerin anisotropic. Ana iya amfani da su don kera na'urar maganadisu ta dindindin injina, na'urorin maganadisu na dindindin, na'urorin maganadisu na dindindin, dindindin maganadisu suspensions, Magnetic tura bearings, broadband Magnetic separators, lasifika, microwave kayan aiki, Magnetic far zanen gado, ji aid, da dai sauransu.

2. Taushi Magnetic Ferrite sun hada da manganese ferrite (MnO.Fe2O3), zinc ferrite (ZnO.Fe2O3), nickel zinc ferrite (Ni-Zn.Fe2O4), manganese magnesium zinc ferrite (Mn-Mg-Zn.Fe2O4) da sauran guda ko Multi-bangaren ferrite. Resistivity ya fi girma fiye da na ƙarfe Magnetic kayan, kuma yana da mafi girma dielectric aiki. Saboda haka, ferrates da cewa suna da duka ferromagnetic da ferroelectric Properties kazalika ferromagnetic da piezoelectric Properties sun fito. A high mita, da Magnetic permeability ya fi girma fiye da na ƙarfe kayan maganadisu, ciki har da nickel-iron gami da sendust. Ana iya amfani da shi a cikin mita kewayo daga ƴan kilohertz zuwa ɗaruruwan megahertz. Yin aiki na ferrite nasa ne na al'ada yumbu tsari, don haka tsari ne mai sauki, kuma mai yawa Ana ceton karafa masu daraja, kuma farashin yana da ƙasa.

Matsakaicin adadin ƙarfin maganadisu jikewa na ferrite yana da ƙasa sosai, yawanci kawai 1/3-1/5 na baƙin ƙarfe. Ferrite yana da ƙasa ajiyar makamashin maganadisu a kowace juzu'in raka'a, wanda ke iyakance amfani da shi a ƙasa mitoci, manyan igiyoyin ruwa, da manyan iyakoki masu ƙarfi inda manyan magnetic ana buƙatar yawan makamashi. Ya fi dacewa da babban mita, ƙananan iko da raunin filin filin lantarki. Ana iya amfani da nickel zinc ferrite azaman eriya sandar sanda da matsakaicin mitar mai canzawa a cikin watsa shirye-shiryen rediyo, da Manganese tutiya ferrite za a iya amfani da a matsayin layin watsa gidan wuta core a TV mai karɓa. Bugu da ƙari, ana amfani da ferrite masu laushi don ƙara na'urori masu auna firikwensin da tace murhu a cikin layukan sadarwa. An kasance masu jujjuya rikodi mai girma na maganadisu amfani da shekaru masu yawa.
