Kumu Hana
ʻO ke kumu kumu o ke ʻano KY e hoʻoheheʻe ʻia nā mea maka Al₂O₃ maʻemaʻe kiʻekiʻe i loko o kahi pahu tungsten/molybdenum ma 2050°C. Hoʻohaʻahaʻa ʻia kahi aniani hua i loko o ka hoʻoheheʻe ʻana, a ukali ʻia e ka wehe ʻana (0.5–10 mm/h) a me ka hoʻololi ʻana (0.5-20 rpm) e hoʻokō i ka ulu kuhikuhi ʻana o nā kristal hoʻokahi α-Al₂O₃. Aia nā hiʻohiʻona nui:
• Nā kristal nui-nui (max. Φ400 mm × 500 mm)
• ʻO ka sapphire ʻano haʻahaʻa haʻahaʻa haʻahaʻa (ka hoʻoheheʻe ʻana o ka nalu <λ/8 @ 633 nm)
• Nā kristal doped (e laʻa, Ti³⁰ doping no ka star sapphire)

Pono o Kyropoulos (KY) Sapphire Crystal Growth Equipment
Hāʻawi ka Kyropoulos (KY) i nā mea hana ulu sapphire crystal ulu ʻana i nā pono ʻenehana like ʻole, hoʻonoho iā ia ma ke ʻano he hopena ʻoki no ka hana ʻenehana. Loaʻa nā pōmaikaʻi nui:
1. Hiki ke Anawaena Nui: Hiki ke ulu i nā kristal sapphire a hiki i ka 12 iniha (300 mm) ke anawaena, e hiki ai i ka hana kiʻekiʻe o nā wafers a me nā ʻāpana optical no nā noi kiʻekiʻe e like me GaN epitaxy a me nā puka makani ʻoihana koa.
2. Ultra-Low Defect Density: Loaʻa i ka dislocation densities <100/cm² ma o optimized thermal field design and precise temperature gradient control, e hōʻoia ana i ka maikaʻi o ka crystal integrity no nā mea optoelectronic.
3. Hana Hana Optical Kiʻekiʻe: Hāʻawi i ka transmittance> 85% i ʻike ʻia e ka spectra infrared (400–5500 nm), koʻikoʻi no nā puka makani laser UV a me nā optics infrared.
4. Advanced Automation: Nā hiʻohiʻona servo-driven pulling mechanisms (± 0.01 mm precision) a me ka magnetic fluid rotary seal (0-30 rpm stepless control), e hōʻemi ana i ka hana kanaka a me ka hoʻonui ʻana.
5. Nā Koho Doping Hiki: Kākoʻo i ka hana maʻamau me nā dopants e like me Cr³⁰ (no ka ruby) a me Ti³⁰ (no ka star sapphire), e mālama ana i nā mākeke niche i nā optoelectronics a me nā mea nani.
6. Hoʻoikaika i ka ikehu: Hoʻemi ʻia ka insulation thermal (tungsten-molybdenum crucible) i ka hoʻohana ʻana i ka ikehu i 80-120 kWh/kg, hoʻokūkū me nā ala ulu ʻē aʻe.
7. Hoʻohua Scalable: Loaʻa i ka hoʻopuka mahina o 5,000+ wafers me nā manawa holo wikiwiki (8-10 mau lā no 30–40 kg crystals), i hōʻoia ʻia e ʻoi aku ma mua o 200 mau hoʻonohonoho honua.
ʻ
8. Paʻa Paʻa Koa: Hoʻohui i nā hoʻolālā pale radiation a me nā mea wela (kū ʻole i 10¹⁶ n/cm²), pono no ka aerospace a me nā noi nuklea.
Hoʻokūpaʻa kēia mau mea hou i ke ʻano KY ma ke ʻano he kumu gula no ka hana ʻana i nā kristal sapphire kiʻekiʻe, e hoʻokau i nā holomua i nā kamaʻilio 5G, quantum computing, a me nā ʻenehana pale.
Nā lawelawe XKH
Hāʻawi ʻo XKH i nā ʻōnaehana turnkey holoʻokoʻa no nā ʻōnaehana ulu kristal sapphire, e hoʻopili ana i ka hoʻonohonoho ʻana, ka loiloi kaʻina hana, a me ka hoʻomaʻamaʻa limahana e hōʻoia i ka hoʻohui ʻana o ka hana. Hāʻawi mākou i nā mea hoʻomaʻamaʻa ulu mua i hōʻoia ʻia (50+) i hoʻohālikelike ʻia i nā pono ʻoihana like ʻole, e hōʻemi nui ana i ka manawa R&D no nā mea kūʻai aku. No nā noi kūikawā, hiki i nā lawelawe hoʻomohala maʻamau ke hana i ka cavity customization (Φ200–400 mm) a me nā ʻōnaehana doping kiʻekiʻe (Cr/Ti/Ni), e kākoʻo ana i nā mea optical kiʻekiʻe a me nā mea pale radiation.
ʻO nā lawelawe i hoʻohui ʻia e pili ana i ka hana ma hope o ka ulu ʻana e like me ka ʻoki ʻana, ka wili ʻana, a me ka polishing, i hoʻokō ʻia e ka nui o nā huahana sapphire e like me nā wafers, tubes, a me nā blanks gemstone. Hāʻawi kēia mau makana i nā ʻāpana mai nā mea uila uila a i ka aerospace. ʻO kā mākou kākoʻo ʻenehana e hōʻoiaʻiʻo i kahi palapala hōʻoia 24 mau mahina a me nā diagnostics mamao manawa maoli, e hōʻoiaʻiʻo ana i ka liʻiliʻi o ka downtime a me ka hoʻomau ʻana i ka hana pono.
