Isicelo seMveliso

Iityhubhu zeSapphire zisetyenziswa kakhulu kumashishini asebenza kakhulu anje ngesemiconductor processing, i-aerospace, optics, kunye nobunjineli bekhemikhali. Ikhono labo lokumelana namaqondo okushisa aphezulu (ukuya kwi-1,600 ° C), kunye nokuchasana kweekhemikhali ezikhethekileyo kwi-acids kunye ne-alkalis, kubenza bafaneleke kwiindawo zokushisa eziphezulu kunye neendawo ezinobungozi. Ukongeza, ukubonakala kwabo okuphezulu kwi-UV ukuya kumaza e-IR kubenza baxabiseke kwiinkqubo zamehlo. Amandla omatshini aphezulu etyhubhu yesafire kunye ne-thermal conductivity zibalulekile kwizicelo apho ukuqina kunye nokutshatyalaliswa kobushushu kuyadingeka, njengakwi-electronics kunye neenkqubo zamandla.

Isishwankathelo sisonke

Ityhubhu yesafire, eyenziwe kwi-99.999% ecocekileyo ye-Al₂O₃ enye yesafire yekristale, yinto ekhethekileyo eyenzelwe ukusetyenziswa kumashishini asebenza kakhulu afana ne-semiconductors, i-aerospace, optics, kunye nobunjineli beekhemikhali. Ngobunzima be-9 kwisikali se-Mohs, inika ukuxhathisa okungaphezulu kokukrala kunye namandla omatshini. Iyakwazi ukusebenza kwiindawo ezigqithiseleyo kunye namaqondo okushisa ukuya kwi-1,600 ° C, okwenza kube yinto efanelekileyo kwiziko lobushushu obuphezulu kunye neendawo ezinobungozi ngenxa yokuchasana kweekhemikhali.

Ukongeza, ityhubhu yesafire ye-thermal conductivity ye-46 W / m·K iqinisekisa ukuchithwa kobushushu okusebenzayo, ngelixa ukukhanya kwayo okuphezulu kwi-UV ukuya kwi-IR yavelengths ixhasa izicelo ezibalulekileyo zokukhanya. Idityaniswe neempawu zayo ezibalaseleyo ze-dielectric, le mveliso sisisombululo esomeleleyo sombane, iinkqubo zamandla, kunye ne-optics. Ngokuqina okuphezulu, ukuzinza, kunye nokusebenza, iityhubhu zesafire zihambisa ukuthembeka kwezinye zezona ndawo zifunwa kakhulu zoshishino kunye nezobuchwepheshe.
