I-Round Ring Block Arc Permanent Ferrite Magnet
Incazelo Yomkhiqizo
I-Ferrite Magnet (eyaziwa nangokuthi uzibuthe we-ceramic) inguzibuthe unomphela.
Ikakhulukazi i-Strontium based (SrFe2O3), ekhiqizwe ngesithasiselo se-Strontium Carbonate ukuze kukhuliswe ukusebenza kusuka ku-Barium ephelelwe yisikhathi (BaFe2O3).
Amandla abo aphoqelelayo avela ku-crystal anisotropy ephezulu ye-strontium iron oxide. Kodwa-ke, izingxenye ze-isotropic nazo zingakhiqizwa lapho kudingeka khona i-multi-pole magnetization elula futhi elula.
Ngokuya ngezici zikagesi, ukumelana ne-ferrite kukhulu kakhulu kunezinsimbi zensimbi ne-alloy magnetic, futhi kunezici eziphezulu ze-dielectric.
Izakhiwo kazibuthe ze-ferrite nazo zibonisa ukufinyeleleka okuphezulu kumafrikhwensi aphezulu.
I-Ferrite ayiqhubeki futhi inokumelana okuphezulu ngokumelene nokugqwala, ama-acids, usawoti, kanye nezinto zokugcoba. Izimo ezivame kakhulu zilula, njengediski, amabhlogo, amasilinda, izindandatho, nama-arcs.
Ozibuthe beFerrite bavame ukusetshenziswa ezinhlelweni ezahlukahlukene emashumini ambalwa eminyaka adlule, njengezipikha, izinjini, namajeneretha.
