Titanium dioxide yog cov ntxhia ntuj siv nyob rau hauv ntau yam kev lag luam, suav nrog kev tsim cov xim, yas thiab tshuaj pleev ib ce. Muaj peb yam tseem ceeb ntawm titanium dioxide:anatase, rutile thiab brookite. Txhua daim ntawv muaj nws cov khoom tshwj xeeb thiab kev siv, ua rau lawv nyiam cov ntsiab lus ntawm kev kawm.
Anatase yog ib qho ntawm feem ntau homtitanium dioxide. Nws yog lub npe hu rau nws lub siab reactivity thiab feem ntau yog siv los ua ib qho catalyst hauv tshuaj lom neeg cov tshuaj tiv thaiv. Anatase kuj tseem siv los ua cov xim hauv cov xim thiab cov txheej txheem thiab hauv kev tsim cov hnub ci cell. Nws cov qauv siv lead ua tshwj xeeb muaj thaj chaw siab, ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv catalytic.
Rutile yog lwm hom titanium dioxide dav siv hauv kev lag luam. Paub txog nws qhov siab refractive index, nws feem ntau yog siv los ua cov xim dawb hauv cov xim, yas, thiab ntawv. Rutile kuj tseem siv los ua UV lim hauv cov tshuaj pleev thaiv hnub thiab lwm yam tshuaj pleev ib ce vim nws cov khoom tiv thaiv UV zoo heev. Nws qhov siab refractive index kuj ua rau nws muaj txiaj ntsig zoo hauv kev tsim cov lo ntsiab muag kho qhov muag thiab iav.
Brookite yog hom tsawg tshaj plaws ntawm titanium dioxide, tab sis nws tseem yog ib qho tseem ceeb ntawm nws txoj cai. Nws yog lub npe hu rau nws cov hluav taws xob conductivity siab thiab yog siv nyob rau hauv zus tau tej cov khoom siv hluav taws xob xws li solar cells thiab sensors. Brookite kuj tseem siv los ua cov xim dub hauv cov xim thiab cov xim, thiab nws cov khoom tshwj xeeb ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv.
Thaum anatase, rutile, thiab brookite yog txhua hom titanium dioxide, lawv txhua tus muaj lawv tus kheej cov khoom thiab kev siv. Kev nkag siab qhov sib txawv ntawm cov ntaub ntawv no yog qhov tseem ceeb rau lawv txoj kev siv tau zoo hauv ntau yam lag luam. Txawm hais tias siv hauv cov ntawv thov catalytic, ua cov xim hauv cov xim, lossis hauv cov khoom siv hluav taws xob, txhua daim ntawv ntawm titanium dioxide muaj nws lub luag haujlwm.
Hauv kev xaus, lub ntiaj teb ntawm titanium dioxide yog ntau haiv neeg, nrog rau anatase, rutile thiab brookite txhua tus muaj lawv tus kheej cov khoom tshwj xeeb thiab kev siv. Los ntawm kev siv los ua catalysts thiab pigments rau nws lub luag haujlwm hauv cov khoom siv hluav taws xob, cov ntaub ntawv ntawm titanium dioxide ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam. Raws li peb txoj kev nkag siab ntawm cov ntaub ntawv no txuas ntxiv txhim kho, peb tuaj yeem cia siab tias yuav siv tshiab rau anatase, rutile, thiab brookite hauv xyoo tom ntej.
