7N Cov Lus Cog Tseg Crystal Crystal thiab Purification Txheej Txheem Qhia nrog Kev Ntsuas

Lub 7n schururium purification txheej txheem ua haujlwm ua ke thaj chaw ua kom rov ua kom zoo thiab taw qhia crystallizies thev naus laus zis. Cov ntsiab lus tseem ceeb thiab cov tsis muaj nqis tau teev hauv qab no:

1. Thaj chaw ua haujlwm
Cov Khoom Siv Tsim

Ntau-txheej Annates lub chaw Melting tej nkoj nquam: Txoj kab uas hla: 30000 hli, qhov siab 50-80 mm, ua los ntawm high-purity quartz lossis graphite.
Cua Sov System: Semi-Virive Resistive Coils nrog Kev Tswj Kub Kub nrog Kev Tswj Xyuas Qhov Kub 0.5 ° Kev Ua Haujlwm Ntau Tshaj ntawm 850 ° C.
Ntsiab lus tseem ceeb

Nqus Plua Plav: ≤1 × 10⁻ 10 Txhawm rau tiv thaiv oxidation thiab paug.
Zone Ncig Tebchaws Ceev: 2-5 mm / h (unidirectional sib hloov ntawm kev tsav qib).
Kev kub thiab txias gradient: 725 ° C ntawm thaj chaw ntawm molten rau pem hauv ntej, txias rau <500 ° C ntawm ntug kev.
Kis: 10-15 mus txog; Tshem tawm efficiency> 99.9% rau impurities nrog cais coeffitation <0.1 (piv txwv li, cu, pb).
2. Directional Crystallization Txheej Txheem
Yaj dhuav

Cov khoom siv: 5n schurium lim los ntawm thaj chaw ua kom zoo.
Melting tej yam kev mob: melted hauv qab inert ary (≥99.99% purity) ntawm 500-520 ° C siv high-zaus induction cua sov.
Kev Tiv Thaiv Melt: High-Purity Graphite Npog rau Sawv Volatilization; Molten pas dej tob kom muaj nyob ntawm 80-120 hli.
Crystallization tswj

Kev Loj Hlob: 1-3 hli / h nrog ib tug ntsug ntsuas kub ntawm 30-50 ° C / CM.
Cua txias zog: dej-txias tooj liab hauv paus rau yuam hauv qab txias; radiative txias rau saum.
Kabmob Segration: FE, NI, thiab lwm cov impurities yog txhawb nqa ntawm cov ciaj ciam av tom qab 3-5 rov qab nce tsheb mus rau qib PPB.
3. Tswj Tswjhwmrics
Parameter txheem tus nqi siv
Thaum kawg Purity ≥99.99999% (7n)
Tag nrho nws yog xim hlau impurities ≤0.1 PPM
Cov ntsiab lus pa xygen cov ntsiab lus ≤5 ppm
Crystal kev taw qhia kev ntxhov siab ntawm ≤2 °
Resistivity (300 k) 0.1-0.3 ω ω ω
Tus txheej txheem zoo
Scalability: ntau-txheej anning tej nkoj nquam nce nkoj nce batch muaj peev xwm los ntawm 3-5 × × piv rau cov qauv tsim.
Kev ua tau zoo: Kho lub tshuab nqus thiab cov thermal tswj kom ua rau qhov kev tshem tawm cov nqi tshem tawm.
Crystal Zoo: Ultra-Qeeb Loj Hlob Cov Nqi (<3 hli / h) kom ntseeg tau qhov qis qis qis thiab ib leeg-siv lub siab ncaj ncees.
Qhov no ua kom zoo nkauj 7n conturium yog qhov tseem ceeb heev rau cov ntawv thov siab, suav nrog cov ntaub ntawv tshwj xeeb, CDTE nyias-zaj duab xis hnub ci hlwb, thiab semiconductor substrates.
