Kukula kwa mawu a 7n Shourium ndi Kuyeretsa Njira Zoyenga ndi Maukadaulo

Njira yoyeretsa 7n yoyeretsa imaphatikiza malo oyeretsa ndi matekinoloje owongolera. Njira yofunika kwambiri ndi magawo omwe afotokozedwa pansipa:

1. Kukonzanso njira yoyenga
Kapangidwe

Nyengo zambiri maboti osungunuka: Diameter 300-500 mm, kutalika 50-80 mm, wopangidwa ndi oyera-quartz kapena graphite.
Kutenthetsa: Makina ozungulira ozungulira oletsa kuwongolera kulondola kwa ± 0,5 ° C ndi kutentha kofunikira kwambiri kwa 850 ° C.
Magawo ofunikira

Vacuum: ≤1 ng × 10 tinth kuti mupewe makutidwe ndi kuipitsidwa.
Kuthamanga kwa maulendo oyendera: 2-5 mm / h (kusinthika kosinthika kudzera pa drive shaft).
Kutentha Kwabwino: 725 ± 5 ° Center molten kutsogolo, kuzirala mpaka <500 °
Padutsa: 10-15 cycles; Kuchotsa ntchito yogwira ntchito> 99.9% ya zosafunikira ndi ma coenation a ma coenations <0.1 (mwachitsanzo, cb).
2. Njira Yowongolera Kuwongolera
Kukonzekera

Zinthu: 5n Shumium yoyeretsedwa kudzera poyenerera.
Zinthu zosungunuka: kusungunuka pansi pa mpweya (≥99.999% kuyera) pa 500-520 °
Chitetezo cha Sungunulani: Chophimba chachikulu choyera kuti muchepetse Volatilization; Dziwe loyera limasungidwa pa 80-120 mm.
Kuwongolera Crystallization

Kukula kwa kukula: 1-3 mm / h yokhala ndi kutentha kwa kutentha kwa 30-50 ° C / cm.
Dongosolo lozizira: Malo ozizira ozizira ozizira kwambiri ozizira; Kuzizirala pamwamba.
Kusanja Kusanja: Mafuta, NI, ndipo zodetsa zina zimalemekezedwa m'malire a tirigu atakumbukira ma 3-5 kukumbukira kuzungulira kwa 3-5 kukumbukira kuzungulira kwa ming'alu ya ma PPB.
3. Zowongolera Zowongolera
Parament Muyezo Vorive
Kuyera Kumaliza ≥999.9999% (7n)
Zonse zosafunikira ≤0.1 ppm
Oxygen nkhani ≤5 ppm
Kupendekera kwa kristalo ≤2 °
Kukana Kukana (300 k) 0.1-0.3 ω ω ω ω ω ω
Magwiridwe ntchito bwino
Scalability: Malo angapo a gawo lonse maboti osungunuka amakulitsa ma batch ndi 3-5 Ì
Kuchita bwino: njira yolondola yothetsera mavuto imathandizira kukweza mitengo yayitali.
Crystal Crain: Ultra-Cherch Cunter (<3 mm / h) onetsetsani kuti kutsika pang'ono ndi kukhulupirika kamodzi.
Soudzu yoyenerera ya 7n ndiyofunikira kwambiri mapulogalamu apamwamba, kuphatikiza zojambula zapamwamba kwambiri, cdte woonda kwambiri maselo owonda dzuwa, ndi magawo a semiconductor.

Zolemba:
kutanthauza zoyeserera zoyeserera zowunikira za anzanu pakuyeretsa.
