I-Alumina, okanye i-Aluminiyam Oxide, inokuveliswa kuluhlu lokucoceka.Amabanga aqhelekileyo asetyenziswa kwimizi-mveliso yanamhlanje ngama-99.5% ukuya kuma-99.9% anezongezo eziyilelwe ukuphucula iipropati.Uluhlu olubanzi lweendlela zokusetyenzwa kwe-ceramic zingasetyenziswa kubandakanya ukwenziwa komatshini okanye ukubunjwa komnatha ukuvelisa ubungakanani obahlukeneyo kunye neemilo zecandelo.
Iiseramikhi ze-Al2O3 zinezincedo zilandelayo:
1. Ubunzima obuphezulu (ubunzima be-MOHS yi-9) kunye nokumelana nokunxiba kakuhle.
2. Amandla alungileyo oomatshini.Amandla okugoba angafikelela kuma-300 ~ 500MPa.
3. Ukumelana nobushushu obugqwesileyo.Ubushushu bokusebenza obuqhubekayo bunokufikelela kwi-1000℃.
4. Ukumelana okuphezulu kunye neempawu ezintle zokufakelwa kombane.Ingakumbi ngobushushu obuphezulu bokugquma (i-Room-temperature resistivity yi-1015Ω•cm) kunye ne-voltage resistance resistance (amandla okugquma yi-15kV/mm).
5. Ukuzinza kakuhle kweekhemikhali.Ayiphenduli nge-asidi ye-sulfuric, i-hydrochloric acid, i-nitric acid kunye ne-hydrofluoric acid.
6. Ukumelana neqondo lokushisa eliphezulu.Ingamelana ngcono nokukhukuliseka kwesinyithi esinyibilikisiweyo njengeBe, Sr, Ni, Al, V, Ta, Mn, Fe kunye ne-Co.
Ke ngoko, iikeramics ze-alumina zisetyenziswa kakhulu kwiindawo zoshishino zanamhlanje.Isetyenziswa ikakhulu kushishino lokwenziwa kwesemiconductor, ishishini lombane, ishishini loomatshini, imekobume yobushushu obuphezulu, ishishini lemichiza, ishishini lokukhanya, ilaphu kunye namanye amacandelo.
I-alumina yimathiriyeli yeceramic esetyenziswa ngokubanzi kwezi zicelo zilandelayo:
✔ izithinteli zombane, izinto zokuchasa umhlwa kwiilaser zegesi, izixhobo zokusetyenzwa kwe-semiconductor (ezifana ne-chuck, i-end effector, iringi yokutywina)
✔ izithinteli zombane kwiityhubhu ze-electron.
✔ iinxalenye zesakhiwo sezixhobo eziphezulu ze-vacuum kunye ne-cryogenic, izixhobo zenyukliya zemitha, izixhobo ezisetyenziswa kubushushu obuphezulu.
✔ Amalungu okumelana nomhlwa, ipiston yeempompo, iivalvu kunye nenkqubo yokudosa, iisampulu zeevalvu zegazi.
✔ iityhubhu ze-thermocouple, i-insulators zombane, imidiya yokusila, izikhokelo zentambo.
