‌7N Tellurium Crystal Gukura no Gutunganya Ibisobanuro birambuye hamwe na tekinike ya tekiniki

7N uburyo bwo kweza bwa tellurium ikomatanya ‌zone gutunganya no hamwe na tekinoroji ya tekinoroji. Ibikorwa byingenzi byingenzi nibisobanuro byerekanwe hano hepfo:

‌1. Inzira yo gutunganya akarere
Igishushanyo mbonera

‌Multi-layer ya buri mwaka ya zone ishonga ubwato: Diameter 300-500 mm, uburebure bwa mm 50-80, bikozwe muri quartz-yera cyane.
Sisitemu yo gushyushya: Igice cya kabiri kizenguruka hamwe nubushyuhe bwo kugenzura ubushyuhe bwa ± 0.5 ° C hamwe nubushyuhe ntarengwa bwo gukora bwa 850 ° C.
Ikirangantego

Vacuum‌: ≤1 × 10⁻³ Pa hose kugirango wirinde okiside no kwanduza.
‌Umuvuduko wurugendo umwe: 2-5 mm / h (kuzunguruka uterekejwe ukoresheje shitingi).
‌Ubushyuhe bukabije: 725 ± 5 ° C imbere ya zone yashongeshejwe, gukonja kugeza kuri <500 ° C kuruhande.
‌Passes‌: inzinguzingo 10-15; gukuraho neza> 99,9% kumwanda hamwe na coefficient zo gutandukanya <0.1 (urugero, Cu, Pb).
‌2. Icyerekezo cyo korohereza inzira
Gutegura gushonga

‌Material‌: 5N tellurium yatunganijwe hakoreshejwe gutunganya zone.
Imiterere yo gushonga: Yashongeshejwe munsi ya gaze ya Ar (≥99.999% yera) kuri 500-520 ° C ukoresheje ubushyuhe bwa induction.
Kurinda gushonga: Igifuniko-cyiza cya grafite igamije guhagarika ihindagurika; ubujyakuzimu bwa pisine bwashizwe kuri mm 80-120.
Igenzura

Igipimo cyubwiyongere: 1-3 mm / h hamwe nubushyuhe bwa veritike ya 30-50 ° C / cm.
Sisitemu yo gukonjesha ‌: Amazi akonje y'umuringa kugirango akonje hasi; gukonjesha imishwarara hejuru.
‌ Gutandukanya umutekano neza: Fe, Ni, nibindi byanduye bikungahaye kumupaka wimbuto nyuma yikurikiranya rya 3-5, bikagabanya kwibanda kurwego rwa ppb.
‌3. Kugenzura Ubuziranenge Ibipimo
Parameter Igiciro Agaciro Reba
Ubuziranenge bwa nyuma ≥99.99999% (7N)
Umwanda wose wibyuma ≤0.1 ppm
Oxygene irimo ≤5 ppm
Icyerekezo cya Crystal gutandukana ≤2 °
Kurwanya (300 K) 0.1–0.3 Ω · cm
Inyungu Zitunganijwe
Ubwinshi bw: Ubwato butandukanye bwa zone buri mwaka gushonga ubwato bwongerera ubushobozi ibyiciro 3-5 × ugereranije nibisanzwe.
‌Ibikorwa byiza: Vacuum neza hamwe nubushyuhe bwumuriro butuma igipimo cyo gukuraho umwanda mwinshi.
Ubwiza bwa kristal:
Iyi 7N tellurium itunganijwe ningirakamaro mubikorwa byateye imbere, harimo ibyuma bifata imirasire ya infragre, CdTe yoroheje ya firime izuba, hamwe na semiconductor substrates.

Ibyifuzo:
vuga amakuru yubushakashatsi avuye murungano rwasuzumwe kubushakashatsi bwa tellurium.
