Ka whakakotahi te tukanga purenga tellurium 7N i ngā hangarau whakapaipai rohe me ngā hangarau whakaata aronga. Kei raro nei ngā taipitopito me ngā tawhā matua o te tukanga:
1. Tukanga Whakapaipai Rohe
Hoahoa Taputapu
Ngā poti rewa porowhita maha-paparanga: Te whānui 300–500 mm, te teitei 50–80 mm, he mea hanga ki te kuata, ki te karāpeti rānei, he mea hanga ki te tino parakore.
Pūnaha whakamahana: He koiri ātete porowhita-haurua me te tika o te whakahaere pāmahana o ±0.5°C me te pāmahana mahi mōrahi o 850°C.
Ngā Tawhā Matua
Korehau: ≤1×10⁻³ Pa puta noa hei ārai i te waikura me te poke.
Tere haere rohe: 2–5 mm/h (hurihanga kotahi-angi mā te pou taraiwa).
Pīroritanga pāmahana: 725±5°C i te taha mua o te rohe rewa, ka whakamatao ki te <500°C i te taha muri.
Ngā Paahitanga: 10–15 huringa; te pai o te tango >99.9% mō ngā poke me ngā tauwehenga wehewehe <0.1 (hei tauira, Cu, Pb).
2. Te Tukanga Whakatiotanga Aronga
Te Whakarite Rewa
Rauemi: 5N tellurium i purea mā te whakamahine rohe.
Ngā tikanga rewa: Ka rewahia i raro i te hau Ar kore mahi (≥99.999% parakore) i te 500–520°C mā te whakamahi i te whakamahana arataki auau-tiketike.
Parenga rewa: Taupoki karāti tino parakore hei pehi i te mimiti; ka puritia te hohonutanga o te puna rewa ki te 80–120 mm.
Mana Whakahaere Tioata
Te tere tipu: 1–3 mm/h me te pikinga pāmahana poutū o te 30–50°C/cm.
Pūnaha whakamatao: Turanga parahi whakamatao-wai hei whakamatao i raro; whakamatao hihi i runga.
Te wehewehenga poke: Ka whakanuia te Fe, Ni, me ētahi atu poke i ngā rohe o te kōpura i muri i ngā huringa rewa anō e 3–5, ka whakaiti i ngā kukū ki ngā taumata ppb.
3. Ngā Inenga Mana Kounga
Tawhā Tohutoro Uara Paerewa
Te parakore whakamutunga ≥99.99999% (7N)
Ngā poke katoa o te konganuku ≤0.1 ppm
Te nui o te hāora ≤5 ppm
Te rerekētanga o te whakatakotoranga karaihe ≤2°
Ātete (300 K) 0.1–0.3 Ω·cm
Ngā Painga o te Tukanga
Whakataurite: Ka whakanui ake ngā poti rewa rohe porowhita maha-apa i te kaha puranga mā te 3–5× ki te whakaritea ki ngā hoahoa tuku iho.
Paitanga: Mā te whakahaere tika o te korehau me te wera ka taea te tango i te paru i ngā tere teitei.
Kounga tioata: Mā ngā tere tipu tino puhoi (<3 mm/h) ka iti te kiato o te nekehanga me te pumau o te tioata kotahi.
He mea nui tēnei tellurium 7N kua whakatikatikaina mō ngā tono matatau, tae atu ki ngā pūoko infrared, ngā pūtau rā kiriata-angiangi CdTe, me ngā papa semiconductor.
Ngā Tohutoro:
e tohu ana i ngā raraunga whakamātautau mai i ngā rangahau arotake-ā-hoa mō te purenga tellurium.
