Xa uphonononga ilizwe lemichiza, enye ikhompawundi ebalasele ngokuguquguquka kwayo kunye nokusetyenziswa kwayo kumashishini kuwo wonke.tetraethyl silicate. Nangona ifomula yayo yeekhemikhali isenokubonakala intsonkothile, ukuyiqonda ingundoqo ekuqondeni indlela le khompawundi eqhuba ngayo ukusabela kweekhemikhali ezibalulekileyo kwiinkalo ezahlukeneyo, ukusuka kwi-elektroniki ukuya kumayeza. Kweli nqaku, siza kuchithaifomula ye-tetraethyl silicatekwaye iphonononge indlela ubume bayo bemolekyuli eyichaphazela ngayo indlela yokuziphatha kwayo kwizicelo zamashishini.

Yintoni iTetraethyl Silicate (TEOS)?

I-Tetraethyl silicate, eyaziwa ngokuba yiI-TEOS, yikhompawundi ye-organosilicon kunye neifomula yemichiza Si(OC2H5)4. Le khompawundi iqulathe aiathom yesilicon (Si)idityaniswe kwisineamaqela e-ethoxy (–OC2H5), ukwenza ukuba aimolekyuli ye-tetrahedral. Xa i-hydrolyzed, iifom ze-TEOSi-silica-isixhobo esiphambili esisetyenziswayo xa kusenziwa izinto ze-elektroniki, izinto zokwaleka nezinye izinto ezahlukeneyo.

Ukuqonda kwayoifomula yemichizakusenza siqonde ukuba kuthenitetraethyl silicateyikhompawundi exabiseke ngolo hlobo kumashishini amaninzi.

Ukwaphula iFomula yeTetraethyl Silicate

Ukuqonda ukubaluleka kwei-tetraethyl silicate (Si(OC2H5)4), makhe siqale sihlolisise iinxalenye zayoisakhiwo semolekyuli:

•Iathom yeSilicon (Si):I-athomu esembindini yemolekyuli, isilicon, idlala indima ebalulekileyo ekwenzeni amaqhina azinzileyo kunye neoksijini kunye neeathom zekhabhoni.

•Amaqela e-Ethoxy (–OC2H5):Iqela ngalinye kumaqela amane e-ethoxy lenziwe nge-athomu ye-oksijini ehlanganiswe neqela le-ethyl (C2H5). Oku kwenza ukuba i-TEOS isebenze kakhulu kwaye ikwazi ukujongana neekhemikhali ezibalulekileyo ezifanai-hydrolysiskwayeukujiya.

Ezi bhondi zinika ii-TEOS iipropati ezizodwa, okwenza kube luncedo kakhulu ekudaleniizinto ezisekelwe kwi-silicakunye nezinye iikhompawundi eziphambili.

Indlela iTetraethyl Silicate Formula Eziphembelela ngayo iiActions zeMichiza

Iifomula ye-tetraethyl silicateibalulekile ekuqondeni ukuziphatha kwayo kwiikhemikhali. Okubaluleke kakhulu, i-TEOS ingena kwinkqubo eyaziwa ngokubai-hydrolysis, apho amaqela e-ethoxy asabela ngayo ngamanzi, okukhokelela ekubunjweni kwei-silicakunye ne-ethanol. Le mpendulo isisiseko kwimveliso yeiifilimu ze-silica ezincincikunye nezinyeizinto ezisekelwe kwi-silicon, ezibaluleke kakhulu kwizinto zombane, iingubo kunye namayeza.

IHydrolysis yeTetraethyl Silicate

Xa i-TEOS isabela ngamanzi, amaqela e-ethoxy athatyathwa ngamaqela e-hydroxyl, ekhokelela ekubunjwenii-silicon hydroxide(Si–OH). Le nkqubo ivelisai-ethanolnjengemveliso. Inkqubo ye-hydrolysis ilawulwa kakhulu kwiindawo zoshishino ukuqinisekisa ukubunjwa komgangatho ophezului-silicaizixhobo.

Ukuxinana kweTetraethyl Silicate

Emva kwe-hydrolysis, iamaqela e-hydroxylyakhiwe inokunxibelelana nezinye iiathom zesilicon, ezikhokelelaukujiyaiimpendulo. Eli nyathelo liyabumbai-silicon-oksijini-silicon(Si–O–Si) iibhondi, ezikhokelela ekudalweni kwesakhiwo senethiwekhi eyaziwa ngokubai-silica. Ikhono le-TEOS ukwenza ezi bhondi zivumela ukuba negalelo ekubunjweniuthungelwano oluqinileyo, oluzinzileyo lwesilika.

Ukusetyenziswa kweTetraethyl Silicate kunye neFomula yayo yeMichiza

Iifomula ye-tetraethyl silicatekunye nokusebenza kwakhona kwenza i-TEOS ibe licandelo elibalulekileyo kumashishini amaninzi:

I-TEOS isandulela esiphambili kwimveliso yei-silicon dioxideIifilimu ezisetyenziswa kwishishini le-elektroniki. Ngokuqonda kwayoifomula yemichiza, abavelisi banokulawula ngokuchanekileyo iumgangathokwayeubukhulukwezi filimu, ukuphucula ukusebenza kweiimicrochipskwayeizixhobo ze-semiconductor.

2. Iingubo kunye neepeyinti

Kwiishishini leengubo, I-TEOS isetyenziselwa ukwenza izikhuselo, iileya ezichasene nemikrwelo kwiindawo ezahlukeneyo. Ukuqulunqwa kwe-silica nge-TEOS hydrolysis kuqinisekisa ukuba iingubo zombini zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.

3. Amayeza

Iifomula ye-tetraethyl silicatenayo ibalulekile kwiishishini lamachizaukuvelisaizixhobo ze-silica, eziyimfuneko ekuqulunqweni kweiipilisi kunye neepilisi. I-TEOS inceda ukuphucula iuzinzo, bioavailability, kwayeamazinga okupheliswayezithako ezisebenzayo kumayeza.

Kutheni Ukuqonda iMiba yeFomula yeTetraethyl Silicate

Ifomula yemichiza yetetraethyl silicateingaphezulu kakhulu kunomfuziselo wekhompawundi. Inika ingqiqo malunga nendlela i-TEOS isebenzisana ngayo nezinye iikhemikhali, indlela eyenza ngayoi-silicauthungelwano, kwaye kutheni isisityebi esibaluleke kangaka kwizicelo zoshishino.
