Maitiro ekuchenesa 7N tellurium anosanganisa matekinoroji ekugadzirisa nzvimbo uye makristaro ekutungamira. Ruzivo rwakakosha rwemaitiro acho nematanho anotsanangurwa pazasi:
1. Maitiro Ekugadzirisa Nzvimbo
Dhizaini yeMidziyo
Mabhoti ekunyungudutsa ane machira akawanda: Dhayamita 300–500 mm, kureba 50–80 mm, akagadzirwa nequartz kana graphite yakachena kwazvo.
Sisitimu yekudziyisa: Makoiri ekudzivirira anodzivirira semicircular ane kurongeka kwekudzora tembiricha kwe ±0.5°C uye tembiricha yepamusoro yekushanda ye 850°C.
MaParameters Akakosha
Vacuum: ≤1×10⁻³ Pa yese kudzivirira oxidation uye kusvibiswa.
Kumhanya kwekufamba kwenzvimbo: 2–5 mm/awa (kutenderera kwemota nenzira imwe chete kuburikidza nedhiraivha shaft).
Kupisa kwakanyanya: 725±5°C pamberi penzvimbo yakanyungudutswa, ichitonhorera kusvika <500°C pamucheto wekutevera.
Kupfuura: 10–15 macycles; kubvisa zvakanaka >99.9% yetsvina ine separation coefficients <0.1 (semuenzaniso, Cu, Pb).
2. Maitiro ekugadzira kristalo nenzira yekutungamira
Kugadzirira Kunyunguduka
Zvinhu: 5N tellurium yakanatswa kuburikidza nekunatswa kwenzvimbo.
Mamiriro ekunyunguduka: Inonyunguduka pasi pegasi reAr risina simba (≥99.999% kuchena) pa500–520°C uchishandisa kupisa kwe induction kwakakwira.
Kudzivirira kunyunguduka: Chifukidziro chegirafiti chakachena kwazvo chinodzivisa kuputika; kudzika kwedziva rakanyunguduka kunochengetwa pa80–120 mm.
Kudzora Kugadziriswa kweCrystallization
Kukura kwemuti: 1–3 mm/awa nekupisa kwakamira kwe30–50°C/cm.
Sisitimu yekutonhodza: Hwaro hwemhangura hwakatonhodzwa nemvura hwekutonhodza pasi; kutonhodza kwemwaranzi pamusoro.
Kupatsanurwa kwetsvina: Fe, Ni, nedzimwe tsvina dzinowedzerwa pamiganhu yezviyo mushure mekunyunguduka kwe3-5, zvichideredza huwandu hwezvinhu kusvika pamazinga eppb.
3. Zviyero zveKudzora Hunhu
Chiratidzo cheParameter Standard Value Reference
Kuchena kwekupedzisira ≥99.99999% (7N)
Kusvibiswa kwese kwesimbi ≤0.1 ppm
Kuwanda kweokisijeni ≤5 ppm
Kutsauka kwekutarisa kwekristaro ≤2°
Kuramba (300 K) 0.1–0.3 Ω·cm
Zvakanakira Maitiro
Kukwanisa Kukura: Mabhoti ekunyungudutsa ane machira akawanda anowedzera kugona kweboka ne3–5× zvichienzaniswa nemagadzirirwo ekare.
Kushanda Nesimba: Kudzora kupisa ne vacuum chaiyo zvinobvumira kubviswa kwetsvina kwakanyanya.
Hunhu hwekristaro: Kukura zvishoma nezvishoma (<3 mm/h) kunoita kuti girazi rive nekristaro shoma uye kuti rive rakakwana.
Iyi 7N tellurium yakanatswa yakakosha pamashandisirwo epamusoro, anosanganisira infrared detectors, CdTe thin-film solar cells, uye semiconductor substrates.
Mareferensi:
zvinoreva ruzivo rwekuyedza kubva kuongororo dzakaongororwa nevezera pamusoro pekucheneswa kwetellurium.
