Titanium dioxide (TiO 2) yog ib qho ntawm cov khoom siv ntau yam thiab siv dav hauv ntau yam kev lag luam, nrog rau cov xim thiab coatings, tshuaj pleev ib ce, thiab khoom noj khoom haus.Muaj peb lub ntsiab siv lead ua hauv tsev neeg TiO2:rutile anatase thiab brookite.Nkag siab txog qhov sib txawv ntawm cov qauv no yog qhov tseem ceeb rau kev siv lawv cov khoom tshwj xeeb thiab qhib lawv lub peev xwm.Hauv qhov blog no, peb yuav ua tib zoo saib cov khoom thiab kev siv ntawm rutile, anatase, thiab brookite, nthuav tawm peb hom kev nthuav dav ntawm titanium dioxide.
1. Rutile Tio2:
Rutile yog daim ntawv ntau tshaj thiab ruaj khov ntawm titanium dioxide.Nws yog tus cwj pwm los ntawm nws cov qauv siv lead ua tetragonal, muaj cov octahedrons zoo sib xws.Qhov kev npaj siv lead ua no muab rutile zoo heev tiv thaiv UV hluav taws xob, ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov tshuaj pleev thaiv hnub thiab UV-thaiv txheej.Rutile Tio 2's siab refractive Performance index kuj txhim khu nws opacity thiab brightness, ua rau nws zoo tagnrho rau tsim cov xim zoo nkauj thiab luam ntawv inks.Tsis tas li ntawd, vim nws cov tshuaj lom neeg ruaj khov, Rutile Tio2 muaj cov ntawv thov hauv catalyst txhawb tshuab, ceramics, thiab cov khoom siv kho qhov muag.
2. Anatase Tio2:
Anatase yog lwm hom crystalline ntawm titanium dioxide thiab muaj cov qauv tetragonal yooj yim.Piv rau rutile,Anatase Tio 2Muaj qhov qis qis dua thiab thaj chaw siab dua, muab nws ntau dua photocatalytic ua haujlwm.Yog li ntawd, nws yog dav siv nyob rau hauv photocatalytic daim ntaub ntawv xws li dej thiab huab cua purification, nws tus kheej-tu qhov chaw, thiab kev kho dej khib nyiab.Anatase kuj tseem siv los ua tus neeg sawv cev dawb hauv papermaking thiab ua ib qho kev txhawb nqa hauv ntau yam tshuaj.Tsis tas li ntawd, nws cov khoom hluav taws xob tshwj xeeb ua rau nws tsim nyog rau kev tsim cov dye-sensitized solar cells thiab sensors.
3. Brookite Tio2:
Brookite yog hom tsawg tshaj plaws ntawm titanium dioxide thiab muaj cov qauv siv lead ua orthorhombic uas txawv ntawm cov qauv tetragonal ntawm rutile thiab anatase.Brookite feem ntau tshwm sim ua ke nrog rau lwm yam ob hom thiab muaj qee yam ua ke.Nws cov haujlwm catalytic yog siab dua rutile tab sis qis dua anatase, ua rau nws muaj txiaj ntsig zoo hauv qee qhov kev siv hnub ci ntawm tes.Tsis tas li ntawd, cov qauv siv lead ua tshwj xeeb ntawm brookite tso cai rau nws siv los ua cov pob zeb hauv cov hniav nyiaj hniav kub vim nws qhov tsis tshua muaj thiab tshwj xeeb zoo li.

Raws li cov ntsiab lus, peb cov ntaub ntawv ntawm rutile, anatase thiab brookite muaj cov qauv siv lead ua thiab cov khoom sib txawv, thiab txhua tus muaj nws qhov zoo thiab kev siv.Los ntawm kev tiv thaiv UV rau photocatalysis thiab ntau dua, cov ntaub ntawv ntawmtitanium dioxideua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, thawb cov ciam teb ntawm kev tsim kho tshiab thiab txhim kho peb lub neej txhua hnub.
Los ntawm kev nkag siab txog cov khoom thiab kev siv ntawm rutile, anatase thiab brookite, cov kws tshawb fawb thiab cov tuam txhab tuaj yeem txiav txim siab thaum xaiv cov titanium dioxide uas zoo tshaj plaws haum rau lawv cov kev xav tau tshwj xeeb, kom ntseeg tau tias kev ua tau zoo thiab cov txiaj ntsig xav tau.
