Alumina, ama Aluminium Oxide, waxaa lagu soo saari karaa noocyo kala duwan oo nadiif ah.Darajooyinka caadiga ah ee loo isticmaalo codsiyada warshadaha casriga ah waa 99.5% ilaa 99.9% oo leh waxyaabo lagu daro oo loogu talagalay in lagu wanaajiyo guryaha.Noocyo kala duwan oo hababka farsamaynta dhoobada ah ayaa lagu dabaqi karaa oo ay ku jiraan makiinada ama samaynta qaabka saafiga ah si loo soo saaro noocyo kala duwan oo cabbir iyo qaababka qaybaha.
Al2O3 ceramics waxay leeyihiin faa'iidooyinka soo socda:
1. Adag-la'aanta sare (Eegyga MOHS waa 9) iyo caabbinta xidhashada wanaagsan.
2. Awood farsamo oo wanaagsan.Awoodda qaloocani waxay noqon kartaa ilaa 300 ~ 500MPa.
3. Iska caabin kulayl oo aad u fiican.Heerkulka shaqada ee joogtada ah wuxuu gaari karaa ilaa 1000 ℃.
4. Iska caabin sare iyo sifooyinka korantada ee wanaagsan.Gaar ahaan heerkul aad u sarreeya oo heerkulkiisu sarreeyo (iska-caabbinta qolka-heerkulka waa 1015Ω•cm) iyo iska caabbinta burburka korantada (xoogga dahaarka waa 15kV/mm).
5. Degganaanshiyo kiimiko oo wanaagsan.Kuma falceliso sulfuric acid, hydrochloric acid, nitric acid iyo hydrofluoric acid.
6. Iska caabbinta daxalka heerkulka sare.Waxay si fiican u diidi kartaa nabaad guurka biraha dhalaalay sida Be, Sr, Ni, Al, V, Ta, Mn, Fe iyo Co.
Sidaa darteed, ceramics alumina ayaa si weyn loogu isticmaalaa beeraha casriga ah ee warshadaha.Inta badan loo isticmaalo warshadaha wax soo saarka semiconductor, warshadaha elektarooniga ah, warshadaha mishiinada, deegaanka heerkulka sare, warshadaha kiimikada, warshadaha iftiinka, dhar iyo beeraha kale.
Alumina waa walxo dhoobo ah oo si ballaaran loogu isticmaalo codsiyada soo socda:
✔ dahaarka korantada, qaybaha iska caabbinta daxalka ee laysarka gaaska, qalabka wax qabad ee semiconductor (sida chuck, end effector, giraanta shaabadda)
✔ dahaarka korantada ee tuubooyinka elektarooniga ah.
✔ Qaybaha qaab dhismeedka qalabka vacuum-sare iyo qaylo-dhaanta, aaladaha shucaaca nukliyeerka, qalabka loo isticmaalo heerkul sare.
✔ Qaybaha iska caabbinta daxalka, piston ee matoorada, valves-ka iyo hababka qiyaasaha, muunad-samaynta valves dhiiga.
✔ Tuubooyinka kulaylaha, dahaarka korantada, warbaahinta shiida, hagaha dunta.
