Titanium dioxide(Tio2) kuyindlela eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi upende, ukugqoka, amapulasitiki nezimonyo. Ikhona ngamafomu amabili aphambili wekristalu: URuter kanye ne-Anatase. Ukuqonda umehluko phakathi kwalezi zinhlobo ezimbili kubalulekile ekukhetheni uhlobo lwe-Tio2 olufanele isicelo esithile.
URutile no-Anatase bobabili izinhlobo ze-titanium dioxide, kepha banezakhiwo ezihlukile ezibenza zilungele ukusetshenziswa okuhlukile. URutile waziwa ngokumelana kwawo okuhle kakhulu kwe-UV kanye nokumelana nesimo sezulu, okwenza kube yisinqumo esithandwayo sezicelo zangaphandle ezifana nopende ongaphandle nezimbobo. Ngakolunye uhlangothi, i-anatase, ibaluleke kakhulu ngomsebenzi wayo ophakeme we-photocatalytic, okwenza kube kuhle ngezicelo ezifana nezingubo zokuzihlanza nezinhlelo zokuhlanza umoya.
Omunye womehluko omkhulu phakathi kweRatile ne-Anatase isakhiwo sawo sekristalu. URutile unesakhiwo se-tetragonal crystal, kanti i-anatase inesakhiwo esiyinkimbinkimbi se-crystal. Lo mehluko wesakhiwo uholela ekushintsheni kwezakhiwo zawo zomzimba nangamakhemikhali, ekugcineni kuthinta ukusebenza kwawo kuzicelo ezihlukile.
Ngokwemigomo ye-Optical Properties,URutile Tio2inenkomba ephakeme evulekayo ne-opacity kune-anatase. Lokhu kwenza i-reatile ukukhetha kokuqala kwezicelo lapho opacity nokukhanya kubaluleke kakhulu, njengopende omhlophe kanye nendwangu. Ngakolunye uhlangothi, i-anatase, inenkomba ephansi evulekayo futhi ivame ukusetshenziswa kuzinhlelo zokusebenza lapho kuvela khona ukucaca nokucaca, njengokugqoko okucacile nama-sunscreens.
Enye into ebalulekile okufanele icatshangelwe lapho ukhetha phakathi kukaRitile no-Anatase Tio2 ngumsebenzi wabo we-photocatalytic. I-Anatase inokusebenza kahle kwe-photocatalytictic kune-rutile, okwenza kube lula ukuthola izinhlelo zokusebenza ezidinga ukuzihlanza nokungcoliswa kwezakhiwo. Le mpahla iholele ekusetshenzisweni kwe-anatase titanium dioxide emikhiqizweni efana nengilazi yokuzihlanza, izinhlelo zokuhlanza umoya kanye nezingubo zokulwa nama-antimicrobial.
Kuhle futhi ukungamangali ukuthi izinqubo zokukhiqiza zeRutile Tio2 kanyeanatase tio2kungahluka, kuholele umehluko ngosayizi wazo wezinhlayiya, indawo engaphezulu, kanye nezimpawu ze-aggglomeration. Lezi zinto zingathinta ukuhlakazeka, ukuqina kanye nokusebenza kwe-tio2 ngezindlela ezahlukahlukene, ukugcizelela kakhulu ukubaluleka kokukhetha uhlobo olufanele lwesicelo esithile.
Ngamafuphi, umehluko phakathi kukaRutile Tio2 no-Anatase Tio2 banweba ngaphezu kwezakhiwo zabo zekristali ekuboneni kwabo, ama-photocatalytic, kanye nokucubungula izakhiwo. Ukuqonda lokhu kwehluka kubalulekile ekwenzeni izinqumo ezinolwazi lapho ukhetha i-Tio2 ngezinhlobo ezahlukahlukene. Ngokukhetha uhlobo olufanele lwe-titanium dioxide, abakhiqizi bangabe ngcono ukusebenza nokusebenza kwemikhiqizo yabo, ekugcineni bahlangabezana nezidingo ezithile zabasebenzisi bokugcina.
