Inqubo yokuhlanzwa kwe-tellurium ye-7N ihlanganisa ubuchwepheshe bokucwengisisa indawo kanye nobuchwepheshe bokukristala ohlangothini. Imininingwane ebalulekile yenqubo kanye nemingcele ichazwe ngezansi:
1. Inqubo Yokucwenga Indawo
Umklamo Wemishini
Izikebhe zokuncibilikisa ezinezingqimba eziningi: Ububanzi obungu-300–500 mm, ukuphakama okungu-50–80 mm, ezenziwe nge-quartz noma i-graphite ehlanzekile kakhulu.
Uhlelo Lokushisa: Amakhoyili amelana nokushisa anesiyingi esincane anokunemba kokulawula izinga lokushisa okungu-±0.5°C kanye nezinga lokushisa lokusebenza eliphakeme elingu-850°C.
Amapharamitha Ayisihluthulelo
I-Vacuum: ≤1×10⁻³ Pa yonke ukuvimbela i-oxidation kanye nokungcola.
Isivinini sokuhamba sendawo: 2–5 mm/h (ukujikeleza okuqondile ngeshafti yokushayela).
I-gradient yokushisa: 725±5°C ngaphambili kwendawo encibilikisiwe, iphola ibe ngaphansi kuka-500°C emaphethelweni alandelanayo.
Amaphasi: imijikelezo eyi-10–15; ukusebenza kahle kokususa >99.9% kokungcola okunama-coefficients okuhlukanisa <0.1 (isb., Cu, Pb).
2. Inqubo Yokwenza Ikristalu Iqondiswe
Ukulungiselela Ukuncibilika
Izinto: I-tellurium ye-5N ihlanzwa ngokuhluzwa kwendawo.
Izimo zokuncibilika: Kuncibilika ngaphansi kwegesi ye-Ar engangenisi lutho (ubumsulwa obungu-≥99.999%) ku-500–520°C kusetshenziswa ukushisa kwe-induction okuvama kakhulu.
Ukuvikelwa kokuncibilika: Isembozo se-graphite esihlanzekile kakhulu ukuvimbela ukuguquguquka; ukujula kwechibi elincibilikisiwe kugcinwa ku-80-120 mm.
Ukulawulwa kwe-Crystallization
Izinga lokukhula: 1–3 mm/h kanye nokuphakama kokushisa okuqondile okungu-30–50°C/cm.
Uhlelo lokupholisa: Isisekelo sethusi esipholile ngamanzi sokupholisa phansi okuphoqelelwe; ukupholisa ngemisebe phezulu.
Ukuhlukaniswa kokungcola: I-Fe, i-Ni, kanye nokunye ukungcola kucebile emingceleni yokusanhlamvu ngemva kwemijikelezo yokuncibilikisa engu-3-5, okunciphisa ukugxila kumazinga e-ppb.
3. Amamethrikhi Okulawula Ikhwalithi
Ireferensi Yenani Elijwayelekile Lepharamitha
Ubumsulwa bokugcina ≥99.99999% (7N)
Ukungcola okuphelele kwensimbi ≤0.1 ppm
Okuqukethwe kwe-oksijini ≤5 ppm
Ukuphambuka kokuma kwekristalu ≤2°
Ukumelana (300 K) 0.1–0.3 Ω·cm
Izinzuzo Zenqubo
Ukusabalala: Izikebhe zokuncibilikisa ezinezingqimba eziningi ze-annular zone zandisa umthamo we-batch ngo-3–5× uma kuqhathaniswa nemiklamo evamile.
Ukusebenza kahle: Ukulawula i-vacuum enembile kanye nokushisa kuvumela amazinga aphezulu okususa ukungcola.
Ikhwalithi yekristalu: Amazinga okukhula ahamba kancane kakhulu (<3 mm/h) aqinisekisa ukuminyana okuphansi kokuguquguquka kanye nobuqotho bekristalu elilodwa.
Le tellurium ecwengekile ye-7N ibalulekile ezinhlelweni zokusebenza ezithuthukisiwe, kufaka phakathi ama-infrared detectors, amaseli elanga e-CdTe thin-film, kanye nama-semiconductor substrates.
Izinkomba:
chaza idatha yokuhlola evela ezifundweni ezibuyekezwe ontanga ngokuhlanzwa kwe-tellurium.
