Ukukhula kwe-Crystal kokukhula kwe-7n Telturium kanye nemininingwane yokuhlanza ngamapharamitha wezobuchwepheshe

Inqubo yokuhlanza i-telturium yokuhlanza i-7n ihlanganisa ubuchwepheshe bokucwilisa indawo kanye ne-Crystallization Technologies. Imininingwane yenqubo ebalulekile namapharamitha kuchaziwe ngezansi:

1. Inqubo yokuhlanza indawo
Idizayini Yemishini

Izikejana ze-Multi-Laner Anbor zone ezinciphile
Uhlelo lokushisa
Amapharamitha asemqoka

I-Vacuum: ≤1 × 10⁻³ PA kuyo yonke ukuvimba i-oxidation nokungcola.
Isivinini sokuhamba kweZone: 2-5 mm / h (ukujikeleza kwe-Unidirectional nge-drive shaft).
I-Card izingalo: 725 ± 5 ° C e-molten zone ngaphambili, ukupholisa ku- <500 ° C kumaphethelo we-trailing.
Ukudlula: Imijikelezo engu-10-15; Ukusebenza kahle kokususa> 99.9% ukungcola okunama-coefficients we-segritget <0.1 (isib. Cu, PB).
2. Inqubo yokuqondisa ikristalu
Kuncibilikisa ukulungiselela

Izinto ezibonakalayo: I-arlurium engu-5n ehlanziwe nge-zone recoin.
Izimo Ezincibilikayo
Ukuvikelwa kwe-Melt: Isembozo se-graphite esiphakeme sokucindezela ukuguquguquka; ukujula okubilisiwe kwe-pool kugcinwe ku-80-120 mm.
Ukulawulwa kwe-Crystallization

Izinga lokukhula: I-1-3 mm / h nge-vertical lokushisa gradient ka-30-50 ° C / cm.
Uhlelo lokupholisa: isisekelo sethusi esipholile samanzi sokupholisa phansi okuphezulu; I-RADIATIVE COOLING POP.
Ukuhlukaniswa Ukungcola: FE, NI, nokunye ukungcola kucetshiswa emingceleni yokusanhlamvu ngemuva kwemijikelezo engu-3-5 ukukhumbula imijikelezo, ukunciphisa ukugxila kumazinga we-PPB.
3. Amamethrikhi wokulawulwa kwekhwalithi
Isethenjwa senani elijwayelekile le-parameter
Ukuhlanzeka kokugcina ≥99.99999% (7n)
Ukungcola kwensimbi okuphelele ≤0.1 ppm
Okuqukethwe komoya-mpilo ≤5 ppm
Ukuphambukiswa kwe-Crystal Oriental ≤2 °
Ukumelana (300 k) 0.1-0.3 ω ω ω · cm
Inqubo inqubo
Ukwehla: Izikebhe ezi-Multi-Laner Zone Scleation zikhuphula umthamo we-batch ngo-3-5 × uma kuqhathaniswa nemiklamo evamile.
Ukusebenza kahle: Ukulawulwa okuqondile nokushisa okushisayo kunika amandla amanani aphezulu okususa ukungcola.
Ikhwalithi ye-Crystal: Amanani wokukhula we-Ultra-Slow-Slow (<3 mm / h) aqinisekise ukuhlukaniswa okuphansi okuphansi kanye nobuqotho be-crystal eyodwa.
Lokhu kuhlaziywa kwe-7n okuhlanjululwe kubalulekile kuzinhlelo zokusebenza ezithuthukile, kufaka phakathi izitholi ze-infrared, amaseli we-CDTE amancane we-solar, kanye nama-semiconductor substrates.

Izinkomba:
Idatha yokuhlola evela ezifundweni ezibukezwe kontanga ngokuhlanzwa kwe-allurium.
