Alumina, kapa Aluminium Oxide, e ka hlahisoa ka mefuta e mengata ea bohloeki.Limaraka tse tloaelehileng tse sebelisoang bakeng sa lits'ebetso tsa morao-rao tsa indasteri ke 99.5% ho isa ho 99.9% ka li-additives tse etselitsoeng ho ntlafatsa thepa.Ho ka sebelisoa mekhoa e mengata e fapaneng ea ts'ebetso ea ceramic e kenyelletsang mochini oa mochini kapa sebopeho sa marang-rang ho hlahisa mefuta e mengata e fapaneng ea boholo le libopeho tsa motsoako.
Li-ceramics tsa Al2O3 li na le melemo e latelang:
1. Boima bo phahameng (bothata ba MOHS ke 9) le ho hanyetsa ho apara hantle.
2. Matla a matle a mochine.Matla a ho kobeha a ka fihla ho 300 ~ 500MPa.
3. Ho hanyetsa mocheso o babatsehang.Ke mocheso o tsoelang pele oa ho sebetsa o ka fihla ho 1000 ℃.
4. High resistivity le thepa e ntle ea ho pata motlakase.Haholo-holo ka mocheso o phahameng oa mocheso o phahameng (Room-themperature resistivity ke 1015Ω•cm) le ho hanyetsa ho senyeha ha motlakase (matla a ho itšireletsa ke 15kV/mm).
5. Botsitso bo botle ba lik'hemik'hale.Ha e sebetsane le sulfuric acid, hydrochloric acid, nitric acid le hydrofluoric acid.
6. Ho hanyetsa mocheso o phahameng oa mocheso.E khona ho hanela khoholeho ea litšepe tse qhibilihisitsoeng joalo ka Be, Sr, Ni, Al, V, Ta, Mn, Fe le Co.
Ka hona, li-ceramics tsa alumina li sebelisoa haholo masimong a kajeno a indasteri.E sebelisoa haholo indastering ea tlhahiso ea semiconductor, indasteri ea lisebelisoa tsa elektroniki, indasteri ea mechini, tikoloho ea mocheso o phahameng, indasteri ea lik'hemik'hale, indasteri e bobebe, masela le likarolo tse ling.
Alumina ke thepa ea ceramic e sebelisoang haholo lits'ebetsong tse latelang:
✔ li-insulators tsa motlakase, likarolo tse hanyetsanang le kutu bakeng sa li-lasers tsa khase, bakeng sa lisebelisoa tsa ho lokisa semiconductor (tse kang chuck, end effector, seal ring)
✔ li-insulator tsa motlakase bakeng sa li-tubes tsa elektronike.
✔ likarolo tsa sebopeho bakeng sa lisebelisoa tse phahameng tsa vacuum le cryogenic, lisebelisoa tsa mahlaseli a nyutlelie, lisebelisoa tse sebelisoang mochesong o phahameng.
✔ Likarolo tse hanyetsanang le kutu, piston ea lipompo, li-valve le li-dosing system, ho etsa sampole li-valve tsa mali.
✔ li-tubes tsa thermocouple, li-insulator tsa motlakase, mecha ea litaba ea ho sila, litataiso tsa likhoele.
