Xwm:
1. Lub cev muaj zog: Hexamethyldisilazane yog cov kua tsis muaj xim nrog cov ntxhiab tsw muaj zog ammonia.
2. Cov Khoom Siv Tshuaj: Hexamethyldisilazane yog qhov yooj yim thiab tuaj yeem ua rau cov kua qaub los ua cov ntsev. Nws tseem tuaj yeem ua rau muaj kev hloov pauv nucleophilic thiab tuaj yeem koom nrog cov tshuaj tiv thaiv electrophilic.
3. Stability: Hexamethyldisilazane yog ib qho chaw ruaj khov thiab tuaj yeem khaws cia ntawm chav tsev kub. Hexamethyldisilazane tuaj yeem ruaj khov nyob rau hauv qee yam mob, tab sis nyob rau hauv qhov kub thiab txias, kev kub siab lossis lwm yam tshuaj tiv thaiv, nws tuaj yeem decompose thiab tso tawm gaseous silazane. Nws yog rhiab heev rau oxygen thiab dej thiab muaj kev cuam tshuam rau oxidation thiab hydrolysis.
4. Solubility: Hexamethyldisilazane yog soluble hauv cov organic solvents xws li ethanol, ether thiab alkanes.
Siv:
1. Cov tshuaj tiv thaiv tshuaj: Hexamethyldisilazane feem ntau yog siv los ua cov tshuaj tiv thaiv rau cov tshuaj rhiab heev rau cov tshuaj reagents lossis intermediates hauv qee qhov chaw kuaj thiab cov ntawv thov kev lag luam. Nws tsim ib txheej inorganic silicone-nitrogen uas tiv thaiv cov tshuaj los ntawm ya raws, oxygen thiab impurities.
2. Cov tshuaj kho deg: Hexamethyldisilazane tuaj yeem siv los txhim kho cov wettability thiab adhesion ntawm cov khoom nto. Nws tuaj yeem siv rau hauv kev tsim cov khoom xws li coatings, adhesives, inks thiab plastics los txhim kho lawv cov kev ua tau zoo ntawm ntau qhov chaw.
3. Semiconductor manufacturing: Hexamethyldisilazane feem ntau yog siv los ua tus neeg sawv cev ncua lossis ua ntej rau kev pabcuam hauv xeev cov tshuaj vapor deposition (SACVD) hauv cov txheej txheem tsim khoom semiconductor. Nws ua rau kev tsim cov purity siab purity silicon nitrogen films siv rau hauv cov khoom tseem ceeb xws li insulating, barrier thiab kis khaubncaws sab nraud povtseg ntawm semiconductor li.
4. Lithography Negative Coatings: Hexamethyldisilazane kuj tuaj yeem siv los ua cov txheej txheem tsis zoo hauv cov txheej txheem photolithography. Nws txhim kho lub smoothness, anti-reflectivity thiab anti-adhesion zog ntawm lub substrate, uas ua rau high-zoo micrographic qauv npaj.
Cov ntaub ntawv kev nyab xeeb:
1. TOXICITY: Hexamethyldisilazane muaj toxicity tsawg rau tib neeg thiab ib puag ncig, tab sis kev sib cuag ntawm daim tawv nqaij, qhov muag thiab ua pa yuav tsum tau zam.
2. Kev nqus pa: Tsis txhob nqus cov pa lossis cov pa roj hexamethyldisilazane.
3. Kev Noj Qab Haus Huv: Tsis txhob sib cuag ntawm hexamethyldisilazane nrog zaub mov lossis dej haus.
5. Kev sib cuag ntawm daim tawv nqaij: Hexamethyldisilazane tuaj yeem ua rau tawv nqaij khaus thiab kev sib cuag ntawm daim tawv nqaij ntev yuav tsum zam. Yog tias qhov tawv nqaij tshwm sim, yaug tam sim nrog xab npum thiab dej ntau.
6. Kev cuam tshuam ib puag ncig: Hexamethyldisilazane tsis yooj yim degradable hauv dej thiab yuav ua rau muaj kev phom sij rau cov kab mob hauv dej. Kev tso tawm ntawm cov khoom mus rau hauv lub cev dej yuav tsum zam.
7. Cia thiab tuav: Hexamethyldisilazane yuav tsum tau muab cia rau hauv qhov chaw qhuav, zoo-ventilated, deb ntawm tshav kub thiab ignition. Cov hnab looj tes tiv thaiv tsim nyog, tsom iav thiab lub ntsej muag tiv thaiv yuav tsum hnav thaum siv thiab tuav.
