I-Alumina, noma i-Aluminium Oxide, ingakhiqizwa ezinhlobonhlobo zokuhlanzeka.Amabanga ajwayelekile asetshenziselwa izinhlelo zokusebenza zezimboni zesimanje angama-99.5% kuya ku-99.9% anezithasiselo eziklanyelwe ukuthuthukisa izakhiwo.Izinhlobonhlobo zezindlela zokucubungula ze-ceramic zingasetshenziswa kufaka phakathi ukwenziwa kwemishini noma ukwakheka kwenetha ukuze kukhiqizwe osayizi abahlukahlukene kanye nokwakheka kwengxenye.
I-Al2O3 Ceramics inezinzuzo ezilandelayo:
1. Ukuqina okuphezulu (ukuqina kwe-MOHS kungu-9) nokumelana nokugqokwa okuhle.
2. Amandla amahle emishini.Amandla ayo okugoba angafika ku-300~500MPa.
3. Ukumelana nokushisa okuhle kakhulu.Izinga lokushisa eliqhubekayo lokusebenza lingafika ku-1000 ℃.
4. Ukumelana okuphezulu kanye nezakhiwo ezinhle zokuvala ugesi.Ikakhulukazi ngokufaka izinga lokushisa eliphezulu okuhle kakhulu (i-Room-temperature resistivity ngu-1015Ω•cm) kanye nokumelana nokuqhekeka kwe-voltage (amandla okuvikela ngu-15kV/mm).
5. Ukuzinza okuhle kwamakhemikhali.Ayisabeli nge-sulfuric acid, i-hydrochloric acid, i-nitric acid ne-hydrofluoric acid.
6. Ukumelana nokugqwala kokushisa okuphezulu.Ingamelana kangcono nokuguguleka kwezinsimbi ezincibilikisiwe njenge-Be, Sr, Ni, Al, V, Ta, Mn, Fe kanye ne-Co.
Ngakho-ke, i-alumina ceramics isetshenziswa kabanzi emikhakheni yesimanje yezimboni.Isetshenziswa kakhulu embonini yokukhiqiza ye-semiconductor, imboni ye-elekthronikhi, imboni yemishini, indawo yokushisa ephezulu, imboni yamakhemikhali, imboni yokukhanya, izindwangu neminye imikhakha.
I-Alumina iyimpahla ye-ceramic esetshenziswa kabanzi kulezi zicelo ezilandelayo:
✔ izivikeli zikagesi, izinto ezimelana nokugqwala zamalaser egesi, zemishini yokucubungula i-semiconductor (njenge-chuck, i-end effector, indandatho yophawu)
✔ izivikeli zikagesi zamashubhu e-electron.
✔ izingxenye zesakhiwo zemishini ye-vacuum ephezulu kanye ne-cryogenic, amadivaysi emisebe yenuzi, amathuluzi asetshenziswa emazingeni okushisa aphezulu.
✔ Izingxenye ezimelana nokugqwala, i-piston yamaphampu, ama-valve namasistimu wokudosa, ama-valve esampula esampula egazi.
✔ amashubhu e-thermocouple, ama-insulators kagesi, imidiya yokugaya, iziqondiso zentambo.
