CAS No. 7783-7-5 Hydrogen Selenide Factory. Dab tsi yog cov neeg muab khoom ntawm Hydrogen Selenide
Hydrogen selenide, tseem hu ua hydroselenic acid nyob rau hauv nws daim ntawv aqueous, muaj cov tshuaj formula H₂Se. CAS tus lej yog 7783-7-5. Qhov sib xyaw no yog cov roj tsis muaj xim uas muaj tshuaj lom thiab ua rau muaj hluav taws. Nov yog qee cov yam ntxwv ntawm hydrogen selenide:
Lub cev muaj zog:
Cov tsos mob: Cov roj tsis muaj xim nrog cov ntxhiab tsw zoo ib yam li cov qe lwj, txawm tias khaus ntau dua.
Kub taw tes: -41.4 ° C.
Melting Point: -85.4 ° C.
Ceev: Ntawm STP, nws yog denser tshaj huab cua.
Solubility: Soluble nyob rau hauv dej thiab polar organic solvents.
Chemical Properties:
Reactivity: Nws yog reactive heev thiab tuaj yeem ignite spontaneously hauv huab cua.
Acidity: Hauv dej, nws tsim cov kua qaub tsis muaj zog, hydroselenic acid (H₂Se).
Decomposition: Nws tuaj yeem decompose rau hauv cov ntsiab lus selenium thiab hydrogen nyob rau hauv qee yam mob.
Kev siv:
Kev Lag Luam Semiconductor: Siv nyob rau hauv kev tsim cov selenium tebchaw rau semiconductors thiab photovoltaic li.
Analytical Chemistry: Siv los ua reagent hauv analytical chemistry.
Kev tshawb fawb: Siv nyob rau hauv kev tshawb fawb tshawb fawb rau kev sib txuas ntawm selenium-muaj cov tebchaw.
Kev txiav txim siab txog kev nyab xeeb:
Toxicity: Tsis tshua muaj tshuaj lom los ntawm kev nqus pa, txawm tias tsis tshua muaj siab; Kev kis tau tuaj yeem ua rau muaj kev noj qab haus huv hnyav nrog rau kev tuag.
Flammability: Flammable gas uas tuaj yeem tsim cov khoom tawg nrog cua.
Kev tuav: Yuav tsum muaj cov txheej txheem kev nyab xeeb nruj, suav nrog kev siv cov fume hoods thiab cov cuab yeej tiv thaiv tus kheej tsim nyog.
Vim nws cov tshuaj toxicity thiab tuav cov cai, hydrogen selenide feem ntau tsis muaj los ntawm cov chaw muag tshuaj. Hloov chaw, nws feem ntau yog tsim nyob rau ntawm qhov chaw hauv chav kuaj lossis cov chaw uas nws siv tam sim ntawd. Cov neeg muag khoom tshwj xeeb uas ua haujlwm rau kev lag luam uas xav tau hydrogen selenide yuav yog lub hauv paus rau kev yuav cov khoom no, txawm hais tias nws muaj ntau dua rau nws tsim raws li qhov xav tau es tsis khaws lossis thauj.
Cov tuam txhab uas muab hydrogen selenide los yog nws cov precursors tej zaum yuav muaj xws li tshwj xeeb tshuaj manufacturers los yog cov uas tshwj xeeb cater rau cov semiconductor kev lag luam. Nco ntsoov xyuas kom ua raws li cov cai hauv zos thiab cov lus qhia kev nyab xeeb thaum soj ntsuam nrog hydrogen selenide, thiab ua haujlwm tsuas yog nyob rau hauv kev tswj hwm nrog kev ntsuas kev nyab xeeb tsim nyog nyob rau hauv qhov chaw.
Shanghai Wechem Chemical Co., Ltd. yog tsim los ntawm ib pab pawg ntawm cov kws tshaj lij thiab cov kws tshaj lij uas muaj kev paub dav thiab kev txawj ntse hauv kev lag luam ntawm cov roj tshwj xeeb thiab cov isotopes ruaj khov. Los ntawm nruam innovation thiab kev tshawb fawb thiab kev loj hlob, peb tsis tu ncua tso cov khoom zoo thiab siab dawb huv kom tau raws li cov kev xav tau ntawm peb cov neeg siv khoom. Yog tias koj xav tau cov khoom no, thov koj xav tiv tauj peb txhua lub sijhawm!
