Ikristale yembewu yesikwere yeSapphire – Isiseko esijolise ngokuchanekileyo sokuKhula kweSapphire yokwenziwa

Ikristale yembewu yesikwere yeSapphire – Isiseko esijolise ngqo ekukhuleni kweSapphire yokwenziwa Umfanekiso obonisiweyo

Inkcazo emfutshane:

Ikristale yembewu yesafire yiqhekeza elincinci, elicocekileyo kakhulu le-single-crystal aluminum oxide (Al₂O₃) elisebenza njengendawo yokuqala yokukhulisa ii-boules ezinkulu zesafire. Isebenza njenge "template," imisela indlela i-lattice orientation ngayo, ulwakhiwo lwekristale, kunye nomgangatho opheleleyo wesafire eyenziwe ngayo.

Inkcazo yeSapphire Seed Crystal

Ikristale yembewu yesafire yiqhekeza elincinci, elicocekileyo kakhulu le-single-crystal aluminum oxide (Al2O3) elisebenza njengendawo yokuqala yokukhulisa ii-boules ezinkulu zesafire. Isebenza njenge "template," imisela indlela i-lattice orientation ngayo, ulwakhiwo lwekristale, kunye nomgangatho uwonke wesafire eyenziwe ngayo.
Kusetyenziswa kuphela iSapphire Seed Crystal enobunyulu obuyi-99.99% nangaphezulu kunye nesakhiwo esigqibeleleyo sekristale, kuba nasiphi na isiphene siya kudluliselwa kwisapphire ekhulileyo, nto leyo echaphazela ukucaca kwayo kokukhanya kunye nokusebenza kwayo koomatshini. Iikristale zembewu zisisiseko esifihliweyo kodwa esibalulekileyo emva kwayo yonke imveliso yesapphire ekumgangatho ophezulu - ukusuka kwi-LED substrates kunye ne-semiconductor wafers ukuya kwi-aerospace optics kunye nezigqubuthelo zewotshi zodidi.

Indlela Ezenziwa Ngayo Iikristale Zembewu Yesafire

Ukuveliswa kweekristale zembewu yesafire yintoinkqubo elawulwa ngokuchanekileyokubandakanya amanyathelo aliqela abalulekileyo:

Ukhetho lweSapphire oluyiNtloko– Iibhola ezinkulu zesafire ezingenasiphako zikhethwa njengezinto ezisisiseko.
Ukuzimisela i-Crystal Orientation– Ngokusebenzisa i-X-ray diffraction, izikhokelo zekristallographic zebhola (i-C-plane, i-A-plane, i-R-plane, okanye i-M-plane) ziyamatshwa.
Ukusika ngokuchanekileyo– Iisarha zentsimbi zedayimani okanye iinkqubo zelaser zisika i-boule zibe zii-wafers ezincinci, iintonga, okanye iibhloko zesikwere ezinendlela echanekileyo.
Ukupolisha kunye nokuSebenza komphezulu– Imbewu nganye ipholishwa kakuhle kakhulu kwaye inyangwa ngamachiza ukuze kususwe imikrwelo emincinci kwaye kuqinisekiswe ukuba umphezulu uthambile ngokweathom.
Ukucoca kunye noLawulo loMgangatho– Ukucoca ngamakhemikhali kususa ungcoliseko, kwaye imbewu nganye ihlolwa ukuba ichanekile na, icocekile, kwaye iqinile na kwisakhiwo sayo ngaphambi kokuba ithunyelwe.

Le nkqubo iqinisekisa ukuba yonke ikristale yembewu yesafire inokumelana nobushushu obugqithisileyo kwaye ilawule ngokuthembekileyo ukukhula kwesafire entsha.

Izicelo – Indlela Iikristale Zembewu Yesafire Ezinceda Ngayo Ukukhula Kwesafire

Iumsebenzi opheleleyoiikristale zembewu yesafirekhulisa isafire entsha yokwenziwa, kodwa zibaluleke kakhulu kuzo zonke iindlela zanamhlanje zokuvelisa i-sapphire.

Indlela yeKyropoulos (KY)
I-Sapphire Seed Crystal ifakwa kwi-alumina enyibilikisiweyo ize ipholiswe kancinci kancinci, nto leyo ebangela ukuba i-sapphire ikhulele ngaphandle kwimbewu. I-KY ivelisa ii-sapphire boule ezinkulu, eziphantsi koxinzelelo ezifanelekileyo kwiindawo ze-LED kunye neefestile ze-optical.

Indlela yeCzochralski (CZ)

Ikristale yembewu yeSapphire inamathele kwintonga yokutsala, ityibilike kwizinto ezinyibilikisiweyo, ize iphakanyiswe kancinci ize ijikelezwe. Isapphire “itsala” kwincibiliko ecaleni kwelathisi yembewu, idale iikristale ezifanayo kakhulu ukuze zisetyenziswe ngamehlo nangokwesayensi.

Indlela yokuTshintshiselana koBushushu (i-HEM)
I-Sapphire Seed Crystal iphumla ezantsi kwe-crucible, kwaye i-sapphire ikhula iye phezulu njengoko isithando somlilo sibanda ukusuka ngaphantsi. I-HEM ingadala iibhloko ezinkulu ze-sapphire ezinoxinzelelo oluncinci lwangaphakathi, ezisetyenziswa kakhulu kwiifestile zeenqwelo moya kunye ne-laser optics.

Ukukhula kweFilimu okuchazwe kwi-Edge-defined Film-fed Growth (EFG)
Ikristale yeSapphire Seed Crystal ikwicala lomngundo; i-alumina enyibilikisiweyo itya nge-capillary action, ikhulisa i-sapphire kwiimo ezikhethekileyo ezifana neentonga, iityhubhu kunye neeribhoni.
