I-Sapphire Square Seed Crystal – I-Substrate Egxile Ngokunemba Yokukhula kweSapphire Yokwenziwa

Incazelo emfushane:

Ikristalu yembewu yesafire iwucezu oluncane, olumsulwa kakhulu lwe-single-crystal aluminium oxide (Al₂O₃) olusebenza njengendawo yokuqala yokutshala ama-sapphire boules amakhulu. Isebenza “njengesifanekiso,” inquma umumo we-lattice, ukwakheka kwekristalu, kanye nekhwalithi iyonke yesafire yokwenziwa evela kuyo.

Uhlolojikelele lwe-Sapphire Seed Crystal

Ikristalu lembewu yesafire ucezu oluncane, olumsulwa kakhulu lwe-single-crystal aluminium oxide (Al2O3) olusebenza njengendawo yokuqala yokutshala ama-sapphire boules amakhulu. Isebenza “njengesifanekiso,” inquma umumo we-lattice, ukwakheka kwekristalu, kanye nekhwalithi iyonke yesafire yokwenziwa evela kuyo.
I-Sapphire Seed Crystal kuphela eno-99.99% noma ubumsulwa obuphakeme kanye nesakhiwo sekristalu esiphelele sisetshenziswa, ngoba noma isiphi isici sizodlulisela kusafire ekhulile, okuthinta ukucaca kwayo kokubona nokusebenza komshini. Amakristalu embewu ayisisekelo esifihliwe kodwa esibalulekile ngemuva kwayo yonke imikhiqizo yesafire yekhwalithi ephezulu - kusukela kuma-substrates e-LED namawafa we-semiconductor kuya kuma-aerospace optics namakhava ewashi aphambili.

Indlela Amakristalu Embewu yeSapphire Enziwa Ngayo

Ukwenziwa kwamakristalu embewu yesafire kuyintoinqubo elawulwa ngokunembaokubandakanya izinyathelo ezimbalwa ezibalulekile:

I-Master Sapphire Selection- Ama-boules amasafire amakhulu, angenasici akhethwa njengomthombo wezinto.
I-Crystal Orientation Ukuzimisela- Ngokusebenzisa i-X-ray diffraction, izikhombisi-ndlela ze-boule (C-plane, A-plane, R-plane, noma i-M-plane) zenziwe imephu.
Ukusika Okuqondile- Amasaha ocingo lwedayimane noma amasistimu e-laser asika i-boule ibe ama-wafer amancane, izinti, noma amabhlogo ayisikwele anomumo oqondile.
Ukupholisha & Ukucutshungulwa kwendawo- Imbewu ngayinye ipholisha kahle kakhulu futhi iphathwe ngamakhemikhali ukuze isuse imihuzuko emincane futhi iqinisekise indawo ebushelelezi ye-athomu.
Ukuhlanza Nokulawula Ikhwalithi- Ukuhlanza amakhemikhali kususa ukungcola, futhi imbewu ngayinye ihlolwa ukuze kutholakale ukunemba kokuma kwayo, ukuhlanzeka, nobuqotho besakhiwo ngaphambi kokuthunyelwa.

Le nqubo iqinisekisa ukuthi yonke ikristalu yezinhlamvu zesafire ingamelana nokushisa okukhulu futhi iqondise ngokuthembekile ukukhula kwesafire entsha.

Izicelo – Indlela Amakristalu Embewu yeSapphire Akwenza Ngayo Ukukhula Kwesafire

Iumsebenzi oyedwaamakristalu embewu yesafire iwukubakhulisa isafire entsha yokwenziwa, kodwa abalulekile cishe kuzo zonke izindlela zesimanje zokukhiqiza isafire.

Indlela ye-Kyropoulos (KY)
I-Sapphire Seed Crystal ifakwa ku-alumina encibilikisiwe bese ipholiswa kancane kancane, okwenza isafire ikhule ngaphandle embewini. I-KY ikhiqiza ama-sapphire boules amakhulu, anengcindezi ephansi alungele ama-substrates e-LED namawindi abonakalayo.

Indlela ye-Czochralski (CZ)

I-Sapphire Seed Crystal ixhunywe entweni yokudonsa, icwiliswe entweni encibilikisiwe, bese iphakanyiswa kancane futhi ijikelezwe. Isafire “idonsa” ekuncibilikeni eduze kwesitezi sembewu, idale amakristalu afanayo kakhulu ukuze asetshenziswe ngokubona nangokwesayensi.

Indlela Yokushintsha Ukushisa (HEM)
I-Sapphire Seed Crystal ihlezi ngaphansi kwe-crucible, futhi isafire ikhulela phezulu njengoba isithando somlilo siphola kusuka ngezansi. I-HEM ingakha amabhulokhi amakhulu esafire anokucindezeleka okuncane kwangaphakathi, asetshenziselwa kabanzi amawindi e-aerospace nama-laser optics.

I-Edge-defined Film-fed Growth (EFG)
Ikristalu ye-Sapphire Seed ihlezi onqenqemeni lwesikhunta; i-alumina encibilikisiwe iphakela ngesenzo se-capillary, isafire ekhulayo ngemimo ekhethekile njengezinduku, amashubhu, namaribhoni.

I-FAQ ye-Sapphire Seed Crystal

Q1: Kungani amakristalu embewu yesafire ebalulekile?
Bachaza i-crystal orientation kanye nesakhiwo se-lattice yesafire ekhulile, iqinisekisa ukufana nokuvimbela amaphutha.

Q2: Ingabe amakristalu embewu angasetshenziswa kabusha?
Ezinye izimbewu zingase ziphinde zisetshenziswe, kodwa abakhiqizi abaningi bakhetha imbewu entsha ukuze igcine ikhwalithi futhi igweme ukungcoliswa.

Q3: Yiziphi iziqondiso ezivame ukusetshenziswa?
Indiza engu-C (yezingxenye ezingaphansi ze-LED), indiza engu-A, indiza engu-R, nendiza engu-M, kuye ngohlelo lwesafire olufunekayo.

Q4: Yiziphi izindlela zokukhula ezincike kumakristalu embewu?
Zonke izindlela zesimanje -KY, CZ, HEM, EFG- zidinga amakristalu embewu.

Q5: Yiziphi izimboni ezithembele ngokungaqondile kumakristalu embewu?
Noma iyiphi insimu esebenzisa isafire yokwenziwa —Ukukhanyisa kwe-LED, i-semiconductor electronics, i-defense optics, amawashi kanokusho- ekugcineni kuncike kumakristalu embewu yesafire.
