Qhov sib txawv tseem ceeb ntawm rutile thiab anatase titanium dioxide yog tias rutile titanium dioxide muaj xim liab sib sib zog nqus thaum qhov tsos ntawm anatase titanium dioxide tsis muaj xim lossis dawb.

Titanium dioxide lossis TiO2 yog cov ntxhia tseem ceeb heev uas muaj ntau yam khoom zoo xws li kev tsim cov hlau titanium, kom tau TiO2 nanoparticles, thiab lwm yam. Ob hom loj ntawm titanium dioxide, rutile thiab anatase) tau tham hauv qab no.

Rutile Titanium Dioxide yog dab tsi?

Rutile titanium dioxide lossis feem ntau rutile yog cov ntxhia uas feem ntau muaj TiO2 nrog lub ntsej muag liab. Nws yog qhov ntau tshaj plaws tshwm sim hauv daim ntawv ntawm titanium dioxide vim nws ruaj khov siab. Rutile muaj polymorphs xws li anatase, brookite, thiab lwm yam. Rutile feem ntau tshwm sim hauv cov pob zeb tsis muaj zog thiab cov pob zeb metamorphic uas nyob rau hauv qhov kub thiab txias.

Daim duab 01: Sib sib zog nqus xim liab Rutile

Thaum xav txog cov qauv siv lead ua ntawm rutile, nws muaj tetragonal unit cell muaj titanium cations thiab oxygen anions. Nyob ntawd, cov titanium cations (Ti+4) hauv cov hlwb no muaj kev sib koom tes ntawm 6. Cov pa oxygen anion (O2-) muaj kev sib koom tes 3. Cov khoom tseem ceeb ntawm rutile yog raws li hauv qab no:

  • High refractive index ntawm pom wavelengths
  • Laj birefringence
  • High dispersion

Peb qhov kev siv tseem ceeb ntawm rutile yog los tsim cov khoom siv hluav taws xob refractory, tsim cov xim titanium dioxide thiab tsim cov hlau titanium. Tsis tas li ntawd, finely hmoov rutile yog ib qho tseem ceeb hauv kev tsim cov xim, yas, thiab ntawv. Tias yog vim li cas cov hmoov zoo rutile muaj xim dawb ci ntsa iab. Ntxiv mus, nao-TiO2 cov khoom siv hauv kev lag luam tshuaj pleev ib ce vim tias cov khoom no yog pob tshab rau pom lub teeb thiab tuaj yeem nqus tau UV teeb tib lub sijhawm.

Anatase Titanium Dioxide yog dab tsi?

Anatase titanium dioxide yog ib daim ntawv ntawm TiO 2uas muaj qhov tsos nrog xim daj rau xiav. Cov ntxhia no tshwm sim raws li cov khoom dub hauv qhov xwm txheej. Cov xim tsaus no yog vim muaj cov impurities. Txwv tsis pub, nws tsis muaj xim lossis dawb.

Daim duab 02: Anatase Mineral

Anatase tshwm sim nrog lub tshuab siv lead ua tetragonal tab sis nws tsis zoo li qhov kev npaj ntawm atoms ntawm rutile (lawv muaj kev sib txawv). Anatase yog optically tsis zoo (thaum rutile yog optically zoo). Nws muaj qhov zoo li xim hlau thaum piv rau cov tsos ntawm rutile. Qee zaum, cov tuam txhab tsim cov pob zeb no ua cov khoom siv hluavtaws vim nws muaj ntau daim ntawv thov hauv kev tsim cov khoom siv hluav taws xob. Piv txwv li: sol-gel txoj kev koom nrog kev tsim cov anatase hom TiO2 Muaj, hydrolysis ntawm titanium tetrachloride (TiCl4) koom nrog.

Rutile vs Anatase Titanium Dioxide

Rutile titanium dioxide lossis feem ntau rutile yog cov ntxhia uas feem ntau muaj TiO2 nrog lub ntsej muag liab. Anatase titanium dioxide yog ib daim ntawv ntawm TiO2 uas muaj qhov tsos nrog daj rau xiav xim.
xim
Nws muaj xim liab sib sib zog nqus thiab nplua hmoov rutile muaj xim dawb ci ntsa iab. Nws muaj xim tsaus thaum muaj impurities tam sim no, tab sis daim ntawv ntshiab tsis muaj xim lossis dawb.
Kev ua haujlwm kho qhov muag
Rutile yog optically zoo. Anatase yog qhov tsis zoo.
Kev tshwm sim
Rutile yog daim ntawv ntau tshaj ntawm titanium dioxide nyob rau hauv xwm. Anatase tsawg dua nyob rau hauv cov xwm thaum piv rau rutile.
YUV Absorption
UV nqus los ntawm rutile yog siab. YCov UV nqus los ntawm anatase yog qis.
Hardness
Lub hardness ntawm rutile yog siab. Anatase nyuaj dua.
Txoj Kev Nyuaj Siab
Lub ntiajteb txawj nqus ntawm rutile yog siab. Lub ntiajteb txawj nqus ntawm anatase tsawg.

Summary – Rutile vs Anatase Titanium Dioxide

Rutile thiab anatase yog ob lub ntsiab lus mineralogical uas muab ob hom loj ntawm titanium dioxide tshwm sim. Qhov sib txawv ntawm rutile thiab anatase titanium dioxide yog tias rutile titanium dioxide muaj xim liab sib sib zog nqus thaum qhov tsos ntawm anatase titanium dioxide tsis muaj xim lossis dawb.
