Aluminiyamu, kapena Aluminiyamu Oxide, imatha kupangidwa mosiyanasiyana.Magiredi odziwika omwe amagwiritsidwa ntchito pamafakitale amakono ndi 99.5% mpaka 99.9% okhala ndi zowonjezera zomwe zidapangidwa kuti ziwonjezere katundu.Njira zingapo zopangira zida za ceramic zitha kugwiritsidwa ntchito kuphatikiza kupanga makina kapena kupanga maukonde kuti apange makulidwe osiyanasiyana ndi mawonekedwe azinthu.
Al2O3 ceramics ali ndi zotsatirazi:
1. Kuuma kwakukulu (kuuma kwa MOHS ndi 9) komanso kukana kuvala bwino.
2. Mphamvu yabwino yamakina.Ndi mphamvu yopindika imatha kufika 300 ~ 500MPa.
3. Kukana kutentha kwambiri.Ndi mosalekeza ntchito kutentha akhoza mpaka 1000 ℃.
4. High resistivity ndi zinthu zabwino zotetezera magetsi.Makamaka ndi kutentha kwambiri kutentha (Room-temperature resistivity ndi 1015Ω•cm) ndi kukana kuwonongeka kwa voteji (mphamvu ya insulation ndi 15kV/mm).
5. Kukhazikika kwamankhwala kwabwino.Sichichita ndi sulfuric acid, hydrochloric acid, nitric acid ndi hydrofluoric acid.
6. Kutentha kwakukulu kwa dzimbiri.Itha kukana kukokoloka kwa zitsulo zosungunuka monga Be, Sr, Ni, Al, V, Ta, Mn, Fe ndi Co.
Chifukwa chake, zoumba za alumina zimagwiritsidwa ntchito kwambiri m'mafakitale amakono.Amagwiritsidwa ntchito kwambiri m'makampani opanga ma semiconductor, mafakitale a zamagetsi, mafakitale amakina, malo otentha kwambiri, makampani opanga mankhwala, mafakitale opepuka, nsalu ndi zina.
Alumina ndi zinthu za ceramic zomwe zimagwiritsidwa ntchito kwambiri pazotsatira zotsatirazi:
✔ zopangira magetsi, zida zolimbana ndi dzimbiri zamagalasi a gasi, zida zopangira semiconductor (monga chuck, end effector, mphete yosindikizira)
✔ ma insulators amagetsi a machubu a elekitironi.
✔ zigawo zamapangidwe a zida za vacuum ndi cryogenic, zida zama radiation ya nyukiliya, zida zomwe zimagwiritsidwa ntchito pakutentha kwambiri.
✔ Zida zolimbana ndi dzimbiri, pisitoni yamapampu, ma valve ndi ma dosing system, mavavu amagazi.
✔ machubu a thermocouple, zoteteza magetsi, media media, maupangiri a ulusi.
