High-purity sulfur

Niaj hnub no, peb yuav sib tham txog cov txiv lws suav siab.
Sulfur yog ib qho khoom muaj nrog ntau cov ntawv thov. Nws pom nyob hauv cov phom phom (ib qho ntawm "FLATIONS"), siv nyob rau hauv cov tshuaj suav ib txwm muaj rau nws cov tshuaj tiv thaiv kev siv roj hmab, thiab ua haujlwm hauv roj hmab vulcanization kom txhim kho cov khoom siv roj hmab. High-purity sulfur, txawm li cas los xij, muaj txawm tias muaj kev siv dav dav:
Cov ntawv thov tseem ceeb ntawm cov qib siab-dawb huv siulfur
1. Electronics Kev Lag Luam
o Semiconductor cov khoom siv: siv los npaj sulfide semiconductors (piv txwv li, cadmium sulfide, zinc sulfide) lossis raws li dopant txhawm rau txhim kho cov khoom siv khoom.
O lithium roj teeb: kev ua tub rog siab-sulfur yog ib qho tseem ceeb ntawm Lithium-Sulphur roj teeb. Nws cov kev coj dawb huv cuam tshuam hluav taws xob ceev thiab lub voj voog.
2. Tshuaj Synthesis
o zus tau los ntawm cov sulfuric acid, sulfur dioxide, thiab lwm yam tshuaj, lossis ua cov sulphur qhov chaw hauv cov synthesis (piv txwv li, cov tshuaj hauv nruab nrab).
3. Cov ntaub ntawv kho qhov muag
o Fabrication ntawm infrared lo ntsiab muag thiab cov ntaub ntawv windows (piv txwv li, chalcogenide tsom iav) vim yog qhov cuam tshuam ntau hauv cov wavelength.
4. Kws ua kws tshuaj
o Cov khoom siv raw rau cov tshuaj (xws li, cov leeg ntshav qab zib) lossis cov nqa khoom rau lub xov tooj cua xov tooj cua.
5. Kev tshawb fawb txuj ci
o Synthesis ntawm superconducting cov ntaub ntawv, quanum dots, lossis nano-sulfur hais, xav tau ultra-siab huv.

High-Purity Sulphur Purification txoj kev los ntawm Sichuan Jingding Tshuab
Lub tuam txhab tsim 6n (99.999%) hluav taws xob-qib siab siab-huv si-purity sulphur siv cov txuj ci hauv qab no:
1. Distillation
A-lub ntsiab cai: cais sulphur (boiling taw tes: 444.6 ° C) los ntawm impurities ntawm lub tshuab nqus tsev lossis tshuab tshuab atmospheric.
O Pros: Kev tsim khoom-teev.
O Cons: Tej zaum yuav tau txais kev impurities nrog cov ntsiab lus kub zoo sib xws.
2. Thaj chaw ua kom zoo
A Lub ntsiab cai: Tsiv ib cheeb tsam molten kom tshem tawm cov neeg impurity cegregation ntawm cov khoom thiab kua theem.
O Pros: tiav cov txheej txheem hluav taws xob ntau puv (> 99.999%).
o Cons: Tsis tshua muaj hauj lwm, tus nqi siab; Haum rau lab lossis me-teev ntau lawm.
3. Tshuaj Vapor Deposition (CVD)
A-lub ntsiab cai: decomposes gaseous sulfides (piv txwv li, h₂s) kom tso nyiaj ntau-huv si-huv sulfur ntawm substrates.
O Pros: Zoo tagnrho rau cov khoom siv nyias-zaj duab xis nrog cov kev coj dawb huv huab.
o Cons: Cov khoom siv nyuaj.
4. Huab cua Crystallization
A Cov ntsiab cai: Recrystallizes sulfur siv cov kuab tshuaj (piv txwv li, cs₂, toluene) kom tshem tawm impurities.
o Pros: Siv tau zoo rau cov organic impurities.
o Cons: Yuav tsum tau tuav cov kuab tshuaj lom.

Cov txheej txheem txhim kho rau cov tshuab hluav taws xob / kho qhov muag (99.999% +)
Kev sib txuas xws li cheeb tsam kom rov ua + CVD lossis CVD + Dolven Crystallization yog ua haujlwm. Lub tswv yim lim tawm tau ua rau hom impurity thiab purity curity uas yuav tsum muaj, kom paub meej thiab meej.
Mus kom ze ua li cas yuav ua li cas cov qauv hybrid pab tau yooj yim, kev ua haujlwm siab ua kom huv si rau cov ntaub ntawv hluav taws xob, khoom siv hluav taws xob, thiab cov ntaub ntawv siab.
