Anatase Titanium Dioxide thiab Rutile Titanium Dioxide sib txawv
Feb 03, 2017

Titanium dioxide (titanium dioxide) stability tshuaj lom neeg, feem ntau, nrog rau feem ntau ntawm cov khoom tsis hnov mob. Titanium dioxide tsuag muaj yog peb siv lead ua: phaj titanium, anatase titanium dioxide thiab rutile titanium dioxide. Titanium yam yog siv lead ua tsis ruaj tsis khov, tsis muaj nqi muaj, anatase titanium dioxide (Anatase) xa mus rau raws li lub hom, thiab rutile titanium dioxide (Rutile) hu ua R-yam, muaj ib tug lattice ruaj khov, yog ib qho tseem ceeb dawb Pigments thiab glazes plooj (veneers) yog superior whiteness, tinting fais fab, qho fais fab, weatherability, thaum tshav kub kub ua hauj thiab tshuaj stability, tshwj xeeb tshaj yog cov-mob toxic, piv rau lwm yam dawb pigments.

Anatase titanium dioxide, cov hom A titanium dioxide. Yog ib cov xim dawb hmoov zoo, muaj zoo lub teeb scattering muaj peev xwm, thiab zoo li no whiteness, nkaum zog, thiab muaj lub siab tshuaj stability, uas tsis yog-mob toxic mov, tsis-stimulation cov neeg nruab nrog cev, lug siv ntau yam muaj chaw, xws li coatings, uas, ntawv thiab number case.

Rutile titanium dioxide, ntawd ces yogR-yam titanium dioxide. Chav sulfuric acid rutile titanium dioxide ntau lawm Tswjhwm kev, ib phau txheej inorganic, ua organic, kho ntsev, tswj calcination, hydrolysis thiab daim ntawv thov rau cov khoom uas lub xws li siv cov Hawj txawm siab heev thiab particle raws li cov tswj, zirconium silicon txhuas phosphorus inorganic txuj kev ncau ntau txheej thiab organic ua tshiab, tus tsim ib tiam tshiab ntawm high-grade hais (ib nrab dej) rutile titanium dioxide. Muaj feem xyuam rau hom architectural coatings, muaj xim, xim los tiv thaiv corrosion, number case, hmoov coatings thiab lwm yam industries.

Rutile Titanium Dioxide thiab anatase titanium dioxide yog ob qho tseem ceeb hom titanium dioxide, vim li cas tias nkawd yog ob tug tseem ceeb hom titanium dioxide uas tim rutile titanium dioxide thiab anatase titanium dioxide tam sim no rau cov lag luam nws kim heev tshaj ob koob ntawm titanium dioxide, tab sis vim yog qhov xwm ntawm ob hom, uas coj lawv sib txawv me ntsis hauv txhua yaam , daim ntawv hauv qab no qhia tau hais tias cov rutile titanium dioxide thiab anatase titanium dioxide qhov txawv yog dab tsi:

1) nrog cov qauv ntawm cov siv lead ua

Titanium dioxide, yog peb siv lead ua hom qauv, uas peb nquag haisrutile titanium dioxide, anatase titanium dioxide, Titanium titanium dioxide, tus peb siv lead ua lug yog tsis sib npaug, rau qhov twg rutile titanium dioxide siv lead ua qauv yog tus tseem ruaj khov, Titanium titanium dioxide yog siv heev me ntsis, vim nws lub qauv ntawm qhov siv lead ua instability mas, li no tsis muaj kev yuav ncua ntev stability of preservation;

(2) Melting taw tes thiab kub

Vim anatase seb yuav txia mus ua ib rutile yam nyob siab kub, melting kis thiab kub cheej nyob ntawm anatase dioxide hom titanium muaj suab tsis tuaj kawm ntawv. Tsuas rutile titanium dioxide muaj lub melting taw tes thiab taw tes kub, rutile titanium dioxide muaj lub melting cheej nyob ntawm 1850 ° C, cua melting point ntawm (1830 ± 15) ° C, pa melting point 1879 ° C, melting taw tes thiab purity ntawm titanium dioxide. Qhov kub cheej nyob ntawm rutile titanium dioxide yog (3200 ± 300) ℃, thaum no kub titanium dioxide ib nyuag nrov heev nthe;

(3) tsis tu ncua Dielectric

Li qhov yooj yim dua dielectric tsis tu ncua txog titanium dioxide, ces nws muaj hluav taws xob zog yav tom ntej. Txiav txim ib co ntawm cov khoom ntawm titanium dioxide lub cev, cov crystallographic orientation txog qhov siv lead ua titanium dioxide nraim rau hauv koj tus account. Tsis tu ncua dielectric txog anatase titania no kuj tsawg kawg, tsuas 48%.

4) conductivity

Titanium dioxide muaj ib semiconductor kev ua tau zoo, nws cov conductivity tsub kom kub thiab txias thiab ua kom sai heev, tiam sis kuj heev rhiab rau hypoxia. Cov permittivity thiab semiconductor khoom ntawm rutile titania tseem ceeb heev rau txoj kev ua lag luam electronics thiab yuav siv tau los ua hauv Cheebtsam xws li tej hub capacitors.

5) hardness

Raws li Mohs hardness teev lawv, rutile titanium dioxide yog 6 ~ 6.5, anatase titanium dioxide yog 5.5 ~ 6.0, yog li hauv tshuaj fiber ntau extinction thiaj li yuav tsum tsis txhob coj thiab kua muag thiab cov anatase.
