7N SUPURIum Crystal Kukura uye Kuchenesa Process Details neTechnical Parameter

Iyo 7N yekuzivisa yekuchenesa maitiro inosanganisa zone kunatswa uye kutungamira crystallation tekinoroji. Kiyi yekugadzirisa zvinhu uye paramita inotsanangurwa pazasi:

1. Maitiro ekunatsa
Zvigadzirwa zvekugadzira

Multi-Layer Annular Zone Roats inonyungudutsa: DIAMETER 300-500 mm, kureba 50-80 mm, yakagadzirwa neyekumusoro-yakakwirira-yekuchena quartz kana graphi.
Kupinza System: Semi-Circular Kuramba Coils ne tembiricha yekudzora kurongeka kwe ± 0.5 ° C uye yakakura yekushandisa tembiricha ye850 c.
Kiyi paramita

Vacuum: ≤1 × 10⁻³ PA dzese kuti vadzivise oxidation uye kusvibiswa.
Zone yekufambisa kumhanya: 2-5 mm / h (unidirection kutenderera kuburikidza ne drive shaft).
Tembiricha Gradient: 725
Passes: 10-15 matanho; Kubviswa kwehunyanzvi> 99.9% yekusvibiswa neSegregation Coefficients <0,1 (semuenzaniso, cu, pb).
2. Nzira dzekuchema nzira
Kugadzirira Kugadzirira

Zvinyorwa: 5n reururium yakanatswa kuburikidza neZone Kunatswa.
Mamiriro ekunyungudika: yakanyungudutswa pasi peInert ar Gasi (≥99.999% Kuchena) pa 500-520 ° C uchishandisa yakakwira-frequency induction kupisa.
Chengetedza Dziviriro: Yakakwirira-Pourity graphite chifukidziro kuti udzvinyire kulattilization; Yakadzika Pool Deptth inochengetwa pa80-120 mm.
Crystallization kutonga

Chiyero chekukura: 1-3 mm / h ne tembiricha tembiricha yeiyo 30-50 ° C / cm.
Kutonhora Sisitimu: Mvura-yakatonhorerwa mhangura base yekumanikidzwa pasi kutonhora; kupora kutonhora kumusoro.
Kusachena Salgreation: Fe, ni, uye kumwe kusachena kunofumiswa pamiganhu yezviyo mushure me3-5 kurangarira mitezo, kuderedza kutarisisa kuPPB mazinga.
3. Mhando dzekudzora metric
Paramende Yakajairwa Kukosha Reference
Yekupedzisira chaiko ≥99.99999% (7n)
Yese simbi isingadzivisiki ≤0.1 PPM
Okisijeni yezvinyorwa ≤5 PPM
Crystal matsauve kutsauka ≤2 °
Kudzvinyirira (300 k) 0.-0.3 · cm
Pindura zvakanakira
Scalability: Mult-Layer Annular Zone Helting Boats anowedzera batch kugona ne 3-5 × achienzaniswa nezvimwe zvigadzirwa zvemamiriro ezvinhu.
Kubudirira: Precise vacuum uye inopisa kutonga inogonesa kukwidziridzwa kure kure kure kubvisa mwero.
Crystal mhando: Ultra-inononoka kukura mitengo (<3 mm / h) chengetedza yakaderera disensity density uye imwechete-crystal yekuvimbika.
Iyi yakanatswa 7n reururium inokonzeresa zvikumbiro zvepamberi, kusanganisira infrared mishonga, cdte yakatsiga-firimu solar maseru, uye Semicononductor Substrates.
