Kufotokozera Kwachidule:

Zipangizo zokulira makristalo a safiro izi zimagwiritsa ntchito njira yotsogola padziko lonse lapansi ya Kyropoulos (KY), yopangidwira kukula kwa safiro wokhala ndi mainchesi akulu komanso opanda vuto lililonse. Njira ya KY imalola kuwongolera molondola kukoka kwa makristalo a mbewu, liwiro lozungulira, ndi kutentha, zomwe zimathandiza kukula kwa makristalo a safiro mpaka mainchesi 300 (300 mm) m'mimba mwake kutentha kwambiri (2000–2200°C). Njira za XKH za KY-method zimagwiritsidwa ntchito kwambiri popanga ma wafers a safiro a C/A-plane a mainchesi 2–12 ndi mawindo owoneka bwino, zomwe zimapangitsa kuti pakhale zotulutsa 20 pamwezi. Zipangizozi zimathandizira njira zogwiritsira ntchito doping (monga Cr³⁰ doping for ruby synthesis) ndipo zimapereka mtundu wa kristalo ndi:

Mfundo Yogwirira Ntchito

Mfundo yaikulu ya njira ya KY imaphatikizapo kusungunula zinthu zopangira za Al₂O₃ zoyera kwambiri mu tungsten/molybdenum crucible pa 2050°C. Kristalo wa mbewu amatsitsidwa mu kusungunuka, kutsatiridwa ndi kuchotsedwa kolamulidwa (0.5–10 mm/h) ndi kuzungulira (0.5–20 rpm) kuti makristalo amodzi a α-Al₂O₃ akule molunjika. Zinthu zazikulu ndi izi:

• Makristalo akuluakulu (osapitirira Φ400 mm × 500 mm)
• Sapphire yowala bwino kwambiri (yosasinthika ndi mafunde <λ/8 @ 633 nm)
• Makristalo opangidwa ndi dope (monga, Ti³⁰ doping ya safiro wa nyenyezi)

Ubwino wa Zipangizo Zokulira za Kyropoulos (KY) Sapphire Crystal

Zipangizo zokulitsa makristalo a safiro zochokera ku Kyropoulos (KY) zimapereka ubwino waukadaulo wosayerekezeka, kuziyika ngati njira yatsopano yopangira mafakitale. Mapindu akuluakulu ndi awa:

1. Kutha kwa Chimake Chachikulu: Kutha kumera makhiristo a safiro mpaka mainchesi 300 (300 mm)m'mimba mwake, zomwe zimathandiza kupanga ma wafer ndi zida zowunikira zogwira ntchito zapamwamba monga mawindo a GaN epitaxy ndi ankhondo.

2. Kuchulukana kwa Ziphuphu Zochepa Kwambiri: Kumakwaniritsa kuchulukana kwa dislocation<100/cm² kudzera mu kapangidwe kabwino ka malo otentha komanso kuwongolera kutentha kolondola, kuonetsetsa kuti makristalo ndi abwino kwambiri pazida zamagetsi.

3. Kugwira Ntchito Kwabwino Kwambiri kwa Kuwala: Kumapereka mphamvu yotumizira uthenga >85% yowonekera ku ma spectra a infrared (400–5500 nm), yofunika kwambiri pa mawindo a UV laser ndi ma infrared optics.

4. Advanced Automation: Ili ndi njira zokokera zoyendetsedwa ndi servo (± 0.01 mm molondola) ndi zisindikizo zozungulira zamaginito (0–30 rpm popanda kusuntha), kuchepetsa kulowererapo kwa anthu ndikuwonjezera kusinthasintha.

5. Zosankha Zosinthasintha Zogwiritsa Ntchito Mankhwala Ochepetsa Mphamvu: Zimathandizira kusintha ndi zinthu monga Cr³⁰ (ya ruby) ndi Ti³⁰ (ya safiro wa nyenyezi), zomwe zimagwira ntchito m'misika yapadera ya optoelectronics ndi zodzikongoletsera.

6. Kugwiritsa Ntchito Mphamvu Mwanzeru: Kuteteza kutentha bwino (tungsten-molybdenum crucible) kumachepetsa kugwiritsa ntchito mphamvu kufika pa 80–120 kWh/kg, kupikisana ndi njira zina zokulira.

7. Kupanga Kowonjezereka: Kupeza ma wafer opitilira 5,000 pamwezi ndi nthawi yofulumira yozungulira (masiku 8-10 a makhiristo olemera 30-40 kg), otsimikiziridwa ndi makina opitilira 200 padziko lonse lapansi.

8. Kulimba kwa Gulu la Asilikali: Kuli ndi mapangidwe osapsa ndi kuwala kwa dzuwa komanso zinthu zosapsa ndi kutentha (zimapirira 10¹⁶ n/cm²), zomwe ndizofunikira kwambiri pa ntchito za ndege ndi nyukiliya.
Zatsopanozi zimalimbitsa njira ya KY ngati muyezo wagolide wopanga makristasi a safiro ogwira ntchito bwino, zomwe zimapangitsa kupita patsogolo mu kulumikizana kwa 5G, quantum computing, ndi ukadaulo wodzitetezera.

Ntchito za XKH

XKH imapereka mayankho athunthu a machitidwe okula a safiro, kuphatikizapo kukhazikitsa, kukonza njira, ndi kuphunzitsa antchito kuti zitsimikizire kuti ntchito ikugwirizana bwino. Timapereka maphikidwe okulira omwe adatsimikiziridwa kale (50+) opangidwa kuti agwirizane ndi zosowa zosiyanasiyana zamafakitale, zomwe zimachepetsa kwambiri nthawi ya kafukufuku ndi chitukuko kwa makasitomala. Pa ntchito zapadera, ntchito zopanga zinthu mwamakonda zimathandiza kusintha mawonekedwe a cavity (Φ200–400 mm) ndi machitidwe apamwamba ogwiritsira ntchito mankhwala osokoneza bongo (Cr/Ti/Ni), omwe amathandizira zida zowunikira zogwira ntchito bwino komanso zinthu zosagwiritsa ntchito ma radiation.

Ntchito zowonjezera phindu zimaphatikizapo kukonza zinthu pambuyo pa kukula monga kudula, kupukuta, ndi kupukuta, zomwe zimaphatikizidwa ndi zinthu zosiyanasiyana za safiro monga ma wafers, machubu, ndi miyala yamtengo wapatali. Izi zimagwira ntchito m'magawo kuyambira zamagetsi mpaka ndege. Thandizo lathu laukadaulo limatsimikizira chitsimikizo cha miyezi 24 komanso kuzindikira zinthu patali nthawi yeniyeni, kuonetsetsa kuti palibe nthawi yogwira ntchito komanso kuti ntchito yopangidwa ikhale yogwira mtima nthawi zonse.
