Amatye anqabileyo eSapphire eKhuliswe kwiLebhu yeMagenta eLungiselelweyo

Inkcazelo emfutshane:

Ilabhu enombala wesafire erhabaxa (iMagenta hue) idityaniswe kusetyenziswa ubuchwephesha be-Hydride Vapor Phase Epitaxy (HVPE), iphumeza iipropathi zekhemikhali zomzimba ezifana nesafire yeMagenta yendalo. Ngolawulo oluchanekileyo lwechromium (Cr³⁺: 0.3-0.7wt%) kunye ne-titanium (Ti⁴⁺: 0.05-0.15wt%) ugxininiso lwe-dopant ngexesha lokwenyani lokujongwa kwe-Raman spectroscopy, ezi kristale zibonisa umbala we-magenta ozinzile (CIE x02 = 0.3; ubude be-waveleng 610±5nm, ukuzaliseka kwe-85±5%). Izinto eziphathekayo zibonisa ubunzima be-Mohs 9 (i-Vickers 2200-2300HV), ukuzinza okungaqhelekanga kwe-thermal (-200 ° C ukuya kwi-800 ° C ngaphandle kokuguqulwa kombala), kunye nokuhanjiswa kokukhanya okuphezulu (> 82% @ 400-700nm). Ngokugqibelela kwekristale (i-inclusions <0.001%) idlula abalingani bendalo kunye nekhono lokuvelisa i-80mm-diameter boules (isivuno se-78%), le safire yobunjineli imele ukuphumelela kweewotshi ze-luxury, i-aerospace components, kunye ne-quantum optical applications.

Amandla omatshini: 2.5GPa amandla acinezelayo kunye> 2GPa amandla okuguquguquka (10× quartz) imelana novavanyo lokuhla lwe-5000

3.Umgangatho weCrystal

· Ulawulo lwesiphene: Imilinganiselo yelattice eqinisekisiweyo ye-XRD (a=4.758Å, c=12.991Å) ihambelana ne-JCPDS#41-1468 nge >99.9% ukungaguquguquki; I-TEM ibonisa <10¹⁵/cm³ izithuba zeoksijini

· Ukuqina: i-40% yesivuno esiphezulu kunendlela yeCzochralski ye-80mm boules (15kg ubunzima bekristale enye)

4.Ubuchule

· Ukwenza ngokuchanekileyo: I-CNC ikrola i-0.1mm micro-features (umzekelo, iigiya ze-tourbillon) intlanganiso ye-ISO 2768-m; umkrolo welaser uphumeza ±1μm ukuchaneka

· Ukugqitywa komphezulu: I-MRF yokupholisha ihambisa i-Ra<0.8nm kunye ne-Mohs 9 yokuxhathisa umkrwelo (umthwalo we-1kg, <1μm indentation)

Izicelo eziphambili

Iinkonzo ze-XKH

Isishwankathelo soShishino lweSapphire eMbala eDityanisiweyo yeXKH
I-XKH isebenzisa i-chemical vapor deposition (CVD) kunye neendlela zokudityaniswa kobushushu obuphezulu ukulima ngokufanelekileyo iisafire ezinemibala eyenziweyo, ezigquma imibala egcweleyo ukusuka kwi-magenta (CIE x=0.36) ukuya kwiblue blue (CIE x=0.05). Ngokulawula ngokuchanekileyo umlinganiselo we-doping we-aluminium oxide kunye neentsimbi eziguqukayo (umzekelo, i-chromium, i-titanium) kwi-0.3-0.7wt% kunye nokusebenzisa i-1700-2050 ° C iinkqubo ze-crystallization yobushushu obuphezulu, inkampani iyaphula imida yemibala yendabuko, ifezekise> 98h% ubulukhuni kunye nokuqina kombala 82% (400–700nm), ukuhlangabezana neemfuno zobucwebe kunye nemigangatho yeshishini.

Kwintengiso kunye nonikezelo, i-XKH iseka uthungelwano lonikezelo lwehlabathi jikelele, ibonelela ngeebrendi zewotshi zaseSwitzerland ezinobunewunewu ngeemeko zokubukela isafire yesiko. Ukusebenzisa intambo yedayimani yokusika (i-wire diameter 50μm) kunye neteknoloji yokugulisa ulwelo, ifezekisa i-0.1mm ye-microstructural echanekileyo, kunye namandla aguquguqukayo adlula i-2GPa kunye nokumelana nokukrazula ukuya kwi-Mohs 9. Ngokusebenzisa i-ISO 2768-m yokulawula umgangatho, ibhetshi nganye iqinisekisa ukutenxa kombala ΔE <0.5 kunye nokufakwa kwe-luxury luxury1% imigangatho.

Iinkonzo zokusetyenzwa ngokwesiqhelo ziqala ukusuka ekusikeni ingot ukuya ekupholisweni kokugqibela, ukuxhasa uyilo oluntsonkothileyo (umzekelo, imingxunya yokuchitha ubushushu obujikelezayo, i-nano-engraving) enonyamezelo ±0.001mm. Kwizacholo, i-XKH ibonelela nge-3-15ct ye-emerald / ukusikwa komjikelo okudityaniswe ne-18K useto lwentsimbi exabisekileyo kwaye yaphuhlisa "i-lattice hollowing" ubuchule, ukunciphisa ubunzima be-3ct gem nge-40% ngelixa iphucula ukuhanjiswa ukuya kwi-89%, ilungele ukufakelwa kobugcisa obuguqukayo.

Zonke iimveliso zibandakanya izatifikethi zokulandela umkhondo ze-blockchain, zibhala yonke inkqubo ukusuka ekunyibilikeni kwezinto ezikrwada ukuya kunikezelo lokugqibela, ukuhlangabezana neemfuno zokulandeleka kumacandelo obutofotofo kunye ne-semiconductor.

Ngokudityaniswa ngokuthe nkqo kwi-R&D-mveliso kunye nenkonzo yetekhnoloji-ukuqhuba kabini, i-XKH iguqula imathiriyeli yelebhu ibe yimveliso yomgangatho ophezulu womthengi we-elektroniki kunye neemarike zobucwebe, kwaye i-XKH iqhubeleka ukukhokela uguquko lwetekhnoloji yobuhle kwiisafire ezinemibala.
