Zatsopano Zogwirira Ntchito Za Ceramic (1)

Zida za ceramic zopangidwa pogwiritsa ntchito ntchito zapadera za ceramic pazinthu zakuthupi monga phokoso, kuwala, magetsi, maginito, ndi kutentha zimatchedwa ceramics functional.Pali mitundu yambiri ya ceramic yomwe imagwira ntchito ndi ntchito zosiyanasiyana.Mwachitsanzo, zida zamagetsi monga ma conductive ceramics, semiconductor ceramics, dielectric ceramics, insulating ceramics zitha kupangidwa molingana ndi kusiyana kwamagetsi a ceramics, omwe amagwiritsidwa ntchito popanga ma capacitor, resistors, kutentha kwambiri komanso zida zothamanga kwambiri mafakitale amagetsi, ma transfoma ndi zida zina zamagetsi.

Semiconductor ceramics

Semiconductor ceramics imatanthawuza ku poly crystalline ceramic zida zopangidwa ndi ukadaulo wa ceramic, wokhala ndi mawonekedwe a semiconductor komanso madulidwe amagetsi apafupifupi 10-6 ~ 105S/m.Ma conductivity a semiconductor ceramics amasintha kwambiri chifukwa cha kusintha kwa zinthu zakunja (kutentha, kuwala, magetsi, mlengalenga ndi kutentha, ndi zina zotero), kotero kuti kusintha kwa thupi kumasintha m'malo akunja kungasinthidwe kukhala chizindikiro chamagetsi kuti apange zigawo zomveka zosiyanasiyana. zolinga.

Magnetic ceramic zinthu

Magnetic ceramics amatchedwanso mabwalo.Zipangizozi zimatanthawuza ma oxide ophatikizika a maginito opangidwa ndi ayoni achitsulo, ayoni okosijeni ndi ayoni ena achitsulo, ndipo pali maginito osokonekera ochepa omwe alibe chitsulo.Zombo nthawi zambiri zimakhala zopangira ma semiconductors, ndipo kupirira kwawo ndikokwera kwambiri kuposa zida zonse zachitsulo, ndipo zimakhala ndi mwayi wotayika pang'ono pakali pano.M'munda wa ma frequency apamwamba ndi ukadaulo wa microwave, monga ukadaulo wa radar, ukadaulo wolumikizirana, ukadaulo wamlengalenga, makompyuta apakompyuta ndi zina zotero, zakhala zikugwiritsidwa ntchito kwambiri.

Kutentha kwakukulu kwa superconducting ceramics

Superconducting oxide ceramics okhala ndi kutentha kwakukulu kwambiri.Kutentha kwake kwapamwamba kwambiri kuli pamwamba pa kutentha kwa madzi a helium, ndipo mawonekedwe a kristalo amachokera ku Dnepropetrovsk.Kutentha kwapamwamba kwambiri kwa ceramics kumakhala ndi kutentha kwapamwamba kwambiri kuposa zitsulo.Chiyambireni kupambana kwakukulu pakufufuza kwa zida zadothi zopangidwa ndi superconducting m'ma 1980s, kafukufuku ndi kugwiritsa ntchito zida za ceramic zotentha kwambiri zachititsa chidwi kwambiri.Pakalipano, kugwiritsa ntchito zipangizo zotentha kwambiri zotentha kwambiri zikupita kuzinthu zamakono, zamagetsi, ndi diamagnetism.

Kuteteza Ceramics

Zomwe zimadziwikanso kuti zida za ceramic.Amagwiritsidwa ntchito ngati ma insulators osiyanasiyana, ma insulating structural parts, switch switch and capacitor support brackets, electronic component packaging zipolopolo, Integrated circuit substrates ndi ma CD zipolopolo, etc. Ma ceramics otetezera ali ndi makhalidwe a resistivity high volume, low dielectric coefficient, low loss factor, high dielectric mphamvu, kukana dzimbiri ndi katundu makina abwino.
