Trimethylaluminum (TMAI)

Trimethylalumane (TMAI)

Trimethylaluminum (TMal), monga gwero lachitsulo-organic (MO), imagwiritsidwa ntchito kwambiri mumakampani opanga ma semiconductor ndipo imagwira ntchito ngati choyambira chachikulu cha atomic layer deposition (ALD), chemical vapor deposition (CVD), ndi metal-organic chemical vapor deposition (MOCVD). Imagwiritsidwa ntchito pokonzekera mafilimu okhala ndi aluminiyamu yoyera kwambiri, monga aluminiyamu oxide ndi aluminiyamu nitride. Kuphatikiza apo, TAl imagwiritsidwa ntchito kwambiri ngati chothandizira komanso chothandizira chake mu organic synthesis ndi polymerization reactions.

Trimethylaluminum (TMAI) imagwira ntchito ngati choyambira cha aluminium oxide deposition ndipo imagwira ntchito ngati Ziegler-Natta catalyst. Ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popanga metal-organic vapor-phase epitaxy (MOVPE). Kuphatikiza apo, TMAI imagwira ntchito ngati methylation agent ndipo nthawi zambiri imatulutsidwa kuchokera ku ma rocket omwe amamveka ngati chofufuzira njira zophunzirira machitidwe a mphepo yam'mlengalenga.

Mafotokozedwe a kampani a 99.9999% Trimethylaluminum - Silikoni yotsika komanso mpweya wochepa (6N TAMI-Low Si ndi Low Ox)

Zindikirani:

Koposa zonse, perekani PPM potengera kulemera kwa chitsulo, ndipo ND = sinapezeke

Njira Yowunikira: ICP-OES/ICP-MS

Zotsatira za FT-NMR (LOD ya FT-NMR organic ndi oxygenated insection ndi 0.1ppm):

Chitsimikizo cha mpweya <0.2 ppm (Chimayesedwa mu FT-NMR)

1. Palibe zonyansa zachilengedwe zomwe zapezeka

Kodi Trimethylaluminum (TMAI) imagwiritsidwa ntchito pa chiyani?

Trimethylaluminum (TMA)- Ntchito ndi Ntchito

Trimethylaluminum (TMA) ndi chinthu choyera kwambiri cha organoaluminium chomwe chimagwira ntchito yofunika kwambiri m'magawo ena apamwamba kwambiri opanga zinthu. Kugwira ntchito kwake bwino komanso kupanikizika kwa nthunzi kumapangitsa kuti chikhale chinthu chosankhidwa kwambiri poika mafilimu enieni okhala ndi aluminiyamu muukadaulo wamagetsi ndi mphamvu, komanso gawo loyambira popanga polyolefin.

TMA yathu imapangidwa motsatira miyezo yokhwima kwambiri ya kuyera, ndi kuwongolera mwamphamvu zonyansa za zinthu zoyambira, zodzazidwa ndi mpweya, ndi zachilengedwe kuti zitsimikizire kuti zikugwira ntchito bwino kwambiri pa ntchito zanu zovuta kwambiri.

Ntchito Zoyambira ndi Makampani:

1. Kupanga Zinthu Zopangira Ma Semiconductor ndi Microelectronics

Mu makampani opanga ma semiconductor, TMA ndi yofunika kwambiri popanga mafilimu opyapyala okhala ndi ma atomu olondola.

* High-k Dielectrics: Amagwiritsidwa ntchito mu Atomic Layer Deposition (ALD) ndi Chemical Npor Deposition (CVD) kuti apange mafilimu opyapyala a aluminiyamu oxide (Al₂O₃), omwe amagwira ntchito ngati high-k gate dielectrics mu transistors zapamwamba ndi zida zokumbukira.

* Ma Compound Semiconductors: Gwero la aluminiyamu lomwe limakondedwa kwambiri mu Metalorganic Vapor Phase Epitaxy (MOVPE) popanga ma semiconductors a III-V omwe amagwira ntchito bwino kwambiri. Zipangizozi ndizofunikira pa:

* Ma Electronics Othamanga Kwambiri: (monga, AlGaAs, AlInGaP)

* Ma Optoelectronics: (monga, AlGaN, AlInGaN) 

2. Mphamvu Yoyera & Photovoltaics

TMA imapangitsa kuti pakhale kugwiritsa ntchito bwino komanso kulimba kwambiri paukadaulo wa mphamvu ya dzuwa.

* Magawo Osinthira Zinthu Pamwamba: Omwe amaikidwa kudzera mu ALD kapena Plasma-Enhanced CVD (PECVD), mafilimu a aluminiyamu oxide (Al₂O₃) ochokera ku TMA amapereka mphamvu yabwino kwambiri yosinthira zinthu pamwamba pa maselo a solar a silicon a crystalline. Izi zimachepetsa kwambiri mphamvu yogwirizanitsa magetsi, zomwe zimapangitsa kuti maselo azitha kusintha bwino komanso azikhala olimba kwa nthawi yayitali.

3. Kuunikira ndi Kuwonetsera Kwapamwamba (LED)

Kupanga ma LED owala kwambiri komanso osagwiritsa ntchito mphamvu zambiri kumadalira TMA yoyera kwambiri.

* Epitaxy ya LED: Imagwira ntchito ngati choyambira cha aluminiyamu mu ma reactor a MOVPE kuti ikule zigawo zogwira ntchito (monga AlGaN) mu ma LED abuluu, obiriwira, ndi a ultraviolet.

* Kusuntha kwa Chipangizo: Kumagwiritsidwa ntchito kuyika mafilimu oteteza aluminiyamu okusayidi kapena aluminiyamu nitride omwe amathandizira kuti zida za LED zigwire bwino ntchito komanso kuti zizitha kugwira ntchito nthawi yayitali.

4. Kupanga kwa Catalysis ndi Polymer mu Mafakitale

Kufunika kwa TMA m'mafakitale kumachokera ku ntchito yake mu catalysis.

* Polyolefin Catalysis: Ndi chinthu choyamba chomwe chimagwiritsidwa ntchito popanga Methylaluminoxane (MAO), chomwe ndi chinthu chofunikira kwambiri chomwe chimagwiritsidwa ntchito popanga Ziegler-Natta ndi metallocene catalyst systems. Makina amenewa amapanga mapulasitiki ambiri a polyethylene ndi polypropylene padziko lonse lapansi.

Makhalidwe Ofunika ndi Ubwino:

* Kuyera Kwambiri: Kuyang'aniridwa mosamala kuti muchepetse zinyalala zomwe zimawononga magwiridwe antchito amagetsi ndi ntchito yothandiza.

* Superior Precursor: Imapereka kusinthasintha kwabwino, kukhazikika kwa kutentha, komanso mawonekedwe oyera owonongeka kuti filimu ikhale yabwino kwambiri.

* Muyezo wa Makampani: Gwero lodalirika komanso lodalirika la aluminiyamu la MOVPE, ALD, ndi CVD m'malo osiyanasiyana padziko lonse lapansi ofufuza ndi chitukuko ndi malo opangira zinthu.

* Maziko a Mapulasitiki: Zinthu zofunika kwambiri zomwe zimathandiza kupanga ma polima a polyolefin osinthasintha komanso ofunikira.

Chodzikanira: Trimethylaluminum ndi chinthu chopangidwa ndi pyrophoric komanso chosavuta kugwiritsa ntchito chinyezi chomwe chimafuna njira zapadera zochigwiritsira ntchito komanso chitetezo. Chidziwitso chomwe chaperekedwa ndi chofotokozera. Ndi udindo wa wogwiritsa ntchito kugwiritsa ntchito chinthuchi motsatira malangizo onse ofunikira achitetezo ndikutsimikiza kuti chikuyenera kugwiritsidwa ntchito mwanjira inayake.
