Oofa Ferrite (ti a tun mọ si oofa seramiki) jẹ oofa ayeraye.
Wọn jẹ ipilẹ Strontium nipataki (SrFe2O3), ti a ṣelọpọ pẹlu arosọ Strontium Carbonate lati mu awọn iṣẹ pọ si lati ipilẹ Barium ti atijo (BaFe2O3).
Agbara ipaniyan ti o dara wọn wa lati anisotropy gara giga ti strontium iron oxide. Bibẹẹkọ, awọn ẹya isotropic tun le ṣe iṣelọpọ nibiti o rọrun ati irọrun ọpọ-polu magnetization ti nilo.
Ni awọn ofin ti awọn abuda itanna, resistivity ti ferrite tobi pupọ ju ti irin ati awọn ohun elo oofa alloy, ati pe o tun ni awọn ohun-ini dielectric ti o ga julọ.
Awọn ohun-ini oofa ti ferrite tun ṣe afihan agbara giga ni awọn igbohunsafẹfẹ giga.
Ferrite kii ṣe adaṣe ati pe o ni ilodi si ipata, acids, iyọ, ati awọn lubricants. Awọn apẹrẹ ti o wọpọ julọ jẹ rọrun, gẹgẹbi disiki, awọn bulọọki, awọn silinda, awọn oruka, ati awọn arcs.
Awọn oofa Ferrite ni a lo ni ọpọlọpọ awọn ohun elo ni ọpọlọpọ awọn ọdun sẹhin, gẹgẹbi awọn agbohunsoke, awọn mọto, ati awọn olupilẹṣẹ.
