Mea fou (1)

O mea sima e gaosia e ala i le fa'aogaina o galuega fa'apitoa o sima i mea fa'aletino e pei o le leo, malamalama, eletise, maneta, ma le vevela e ta'ua o mea fa'atino.E tele ituaiga o sima aoga ma eseese fa'aoga.Mo se faʻataʻitaʻiga, o mea faʻaeletoroni e pei o serami faʻamalosi, semiconductor ceramics, dielectric ceramics, insulating ceramics e mafai ona faia e tusa ai ma le eseesega i mea eletise o ceramics, lea e faʻaaogaina e fai ai capacitors, resistors, maualuga-veve ma maualuga-vave masini i le alamanuia faaeletonika, transformers ma isi vaega faaeletonika.

Semiconductor keramika

Semiconductor ceramics o loʻo faʻatatau i poly crystalline ceramic mea faʻapipiʻiina e tekinolosi sima, faʻatasi ai ma uiga semiconductor ma le eletise eletise e uiga i le 10-6 ~ 105S / m.O le conductivity o semiconductor ceramics e suia tele ona o suiga i tulaga i fafo (vevela, malamalama, eletise eletise, siosiomaga ma le vevela, ma isi), o lea o le suiga o le tino i le siosiomaga i fafo e mafai ona liua i faailo eletise e fai ai vaega maaleale mo eseese. faamoemoega.

Mea maneta sima

O mea maneta e ta'ua foi o vaa.O mea nei e fa'asino i mea fa'amaneta tu'ufa'atasi o lo'o iai ion u'amea, ions okesene ma isi ion u'amea, ma o lo'o i ai ni nai mea fa'amaneta e leai ni u'amea.O Ferries e tele lava semiconductors, ma o latou resistivity e sili atu le maualuga nai lo mea masani o mea maneta, ma o loʻo i ai le lelei o le leiloa o le taimi nei.I le fanua o le tele o taimi ma microwave tekinolosi, e pei o radar tekinolosi, tekinolosi fesootaiga, tekinolosi avanoa, komepiuta faaeletonika ma isi, ua faaaogaina lautele .

Osimea fa'aoso maualuga le vevela

Superconducting oxide ceramics ma maualuga atu le vevela vevela.O lona maualuga maualuga o le vevela o loʻo i luga aʻe o le vai vevela o le helium, ma o le fausaga tioata e tupu mai i le Dnepropetrovsk structure.O ceramics superconducting vevela maualuga e maualuga atu le vevela sili atu nai lo metala.Talu mai le tele o mea na tupu i le suʻesuʻega o superconducting ceramics i le 1980s, o le suʻesuʻega ma le faʻaogaina o mea faʻapipiʻi vevela maualuga ua tosina mai ai le tele o le gauai.I le taimi nei, o le faʻaogaina o mea e faʻaogaina ai le maualuga o le vevela o loʻo atiaʻe agai i luga o le taimi nei talosaga, faʻaoga eletise, ma diamagnetism.

Insulating Ceramic

Ua ta'ua foi o masini keramika.E faʻaaogaina e pei o insulators eseese, insulating vaega fausaga, fusi faaili ma puipui lagolago capacitor, atigi afifi vaega faaeletonika, substrates matagaluega tuufaatasia ma atigi afifi, ma isi. Insulating ceramics o loo i ai uiga o le voluma resistivity maualuga, coefficient dielectric maualalo, vaega gau maualalo, malosi dielectric maualuga, corrosion teteʻe ma meatotino lelei masini.
