Ukuqonda umehluko phakathi kwe-anatase ne-rutile tio2

I-Titanium Dioxide (Tio2) iwumbala omhlophe osetshenziswa kabanzi kwizimboni ezahlukahlukene, kufaka phakathi upende, izimbobo, amapulasitiki nezimonyo. Ikhona ezinhlanganweni ezahlukahlukene zekristali, lezi zinhlobo ezimbili ezivame kakhulu ukuba yi-anatase kanye rutile. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili ze-tio2 kubalulekile ekukhetheni upende ofanele isicelo esithile.

I-anatase ne-rutile kukhona ama-polymorphs we-tio2, okusho ukuthi banezinhlaka ezifanayo zamakhemikhali kodwa ezahlukene zezinhlaka ze-crystal, okuholela ezicini ezahlukahlukene kanye nezimpawu zokusebenza. Omunye umehluko omkhulu phakathianatase tio2Futhi uRutile Tio2 isakhiwo sawo sekristalu. I-anatase inesakhiwo se-tetragonal, kanti uRutile unesakhiwo se-tenserter tetragonal. Lo mehluko wesakhiwo uholela ezinguquko ezinhlakeni zabo ezingokomzimba nezamakhemikhali.

Ngokuya nge-Optical Properties, i-rutile tio2 inenkomba ephakeme evundayo ne-opacity enkulu kune-anatase tio2. Lokhu kwenza i-ruter tio2 ukukhetha kokuqala kwezicelo ezidinga i-opacity ephezulu nobumsulwa, njengopende nezimbobo. Uma kunjalo, ngakolunye uhlangothi, kwaziwa ngomsebenzi wayo omuhle we-photocatalytic.

Enye into ebalulekile okufanele icatshangelwe lapho kuqhathaniswa ne-anatase ne-rutile tio2 yinto yabo yezinhlayiyana nendawo engaphezulu. I-Anatase Tio2 imvamisa inendawo enkulu yobuso nobukhulu obuncane bezinhlayiyana, okunomthelela ekusebenzeni kwayo okuphezulu nokusebenza kwe-photocatalytic.URutile Tio2, ngakolunye uhlangothi, inokusatshalaliswa kosayizi ofanayo ngokwengeziwe kanye nendawo ephansi engaphezulu, okwenza kube lula kakhulu ukuthola izinhlelo zokusebenza lapho kuguqulwa khona usayizi we-Partic, njengamaplastiki kanye nezimonyo.

Kuhle futhi ukukwazi ukuthi izinqubo zokukhiqiza ze-anatase kanye ne-rutile tio2 zingaholela ekutheni izinguquko ekuhlanzekeni kwazo kwamakhemikhali nasekwelashweni komhlaba. Lezi zinto zithinta ukungafani kwazo, ukuhambisana nezinye izithako, kanye nokusebenza okuphelele ngezindlela ezahlukene.

Ngokufingqa, kuyilapho bobabilii-anatase ne-rutile tio2Ingabe imibala emhlophe ebalulekile enezindawo ezihlukile, ukuqonda umehluko wazo kubalulekile ekukhetheni uhlobo olufanele isicelo esithile. Noma ngabe kunesidingo so-opacity ophakeme nobunzima kupende kanye nokumboza umsebenzi we-photocatalytic aphezulu ezitsheni ezinobungani bemvelo, ukukhetha phakathi kwe-anatase ne-rutile tio2 kungathinta kakhulu ukusebenza nokusebenza komkhiqizo wokugcina. Ngokubheka ukwakheka kwekristalu, izakhiwo ze-Optical, usayizi wezinhlayiyana kanye nezindawo ezingaphezulu zefomu ngalinye, abakhiqizi namakhemithi bangenza izinqumo ezinolwazi zokuthola imiphumela efiselekayo yokwakheka kwabo.
