ityhubhu yesafire yeCZmethod KY indlela yokumelana nobushushu obuphezulu i-Al2O3 99.999% isafire enye yekristale

Inkcazo emfutshane:

Le tube yesafire esebenza kakhulu yenziwe kusetyenziswa iindlela zeCzochralski (CZ) kunye neKyropoulos (KY), iqinisekisa umgangatho ophezulu kunye nokuchaneka. Yenziwe yi-99.999% ye-Al₂O₃ single crystal sapphire ecocekileyo, le tube iqhayisa ngokucaca okugqwesileyo kokukhanya kunye namandla angaqhelekanga oomatshini. Ngenxa yokumelana kwayo nobushushu obuphezulu, inokumelana neemeko ezinzima, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kwiindawo ezinzima ezifana nokucubungula i-semiconductor, ii-ovens zobushushu obuphezulu, kunye namashishini eekhemikhali.

I-Sapphire, enobunzima bayo obungaqhelekanga, ingaphantsi kancinci kwedayimani, inika ukumelana nokukrwela okuphezulu. Ngaphezu koko, ukuzinza kwayo okumangalisayo kobushushu kuvumela ukusebenza rhoqo kwimisebenzi yobushushu obuphezulu. Ulwakhiwo lwekristale enye yetyhubhu luqinisekisa ukungangeni kakuhle kweekhemikhali kunye nokuqhuba kobushushu, okubalulekileyo ekusetyenzisweni ngokuchanekileyo.
Le tyhubhu yesafire ifanelekile kumashishini amaninzi anzima, kuquka i-aerospace, i-optics, i-electronics, kunye nobunjineli beekhemikhali, apho ukuqina, ukumelana nobushushu, kunye nobunyulu kubaluleke kakhulu. Inkqubo yayo yokuvelisa ephucukileyo iqinisekisa imveliso ethembekileyo, iqinisekisa ukusetyenziswa kwexesha elide kunye nozinzo phantsi kweemeko zokusebenza ezinzima.

Ityhubhu yepropathi yetyhubhu yesafire yeXINKEHUI

Isicelo seMveliso

Iityhubhu zesafire zisetyenziswa kakhulu kumashishini asebenza kakuhle njengokucubungula i-semiconductor, i-aerospace, i-optics, kunye nobunjineli beekhemikhali. Ukukwazi kwazo ukumelana namaqondo obushushu agqithisileyo (ukuya kuthi ga kwi-1,600°C), kunye nokumelana okungaqhelekanga kweekhemikhali kwi-acids kunye ne-alkalis, kuzenza zilungele ii-oven ezishushu kakhulu kunye neendawo ezingcolisayo. Ukongeza, ukucaca kwazo okuphezulu kwii-wavelengths ze-UV ukuya kwi-IR kuzenza zibe luncedo kwiinkqubo ze-optical. Amandla aphezulu oomatshini kunye nokuqhuba kobushushu betyhubhu yesafire nakho kubalulekile kwizicelo apho kufuneka ukuqina kunye nokuchithwa kobushushu, njengakwiinkqubo ze-elektroniki kunye namandla.

Isishwankathelo Esipheleleyo

Ityhubhu yesafire, eyenziwe nge-99.999% ye-Al₂O₃ single crystal safire, sisixhobo esikhethekileyo esenzelwe ukusetyenziswa kumashishini asebenza kakuhle afana nee-semiconductors, i-aerospace, i-optics, kunye nobunjineli beekhemikhali.

Ingasebenza kwiindawo ezishushu kakhulu ezinamaqondo obushushu afikelela kwi-1,600°C, nto leyo eyenza ukuba ifaneleke kwii-ovens ezishushu kakhulu kunye nezicwangciso zokubola ngenxa yokumelana kwayo okugqwesileyo kweekhemikhali.

Ukongeza, ukuhanjiswa kobushushu kwetyhubhu yesafire ye-46 W/m·K kuqinisekisa ukusasazwa kobushushu okusebenzayo, ngelixa ukukhanya kwayo okuphezulu kwi-UV ukuya kwi-IR wavelengths kuxhasa usetyenziso olubalulekileyo lwe-optical. Idityaniswe neempawu zayo ezibalaseleyo ze-dielectric, le mveliso sisisombululo esomeleleyo se-elektroniki, iinkqubo zamandla, kunye ne-optics. Ngokuqina okuphezulu, uzinzo, kunye nokusebenza, iityhubhu zesafire zinika ukuthembeka kwezinye zezona ndawo zinzima kakhulu kwezoshishino kunye nezobuchwepheshe.
