Titanium (IV) oxide CAS 13463-67-7 Taw qhia
zoo
Dawb amorphous hmoov. Muaj peb qhov sib txawv ntawm titanium dioxide uas muaj nyob rau hauv qhov: rutile yog tetragonal siv lead ua; Anatase yog tetragonal siv lead ua; Plate perovskite yog siv lead ua orthorhombic. Daj nyob rau hauv me ntsis kub thiab xim av nyob rau hauv muaj zog tshav kub. Insoluble nyob rau hauv dej, hydrochloric acid los yog nitric acid los yog dilute sulfuric acid thiab organic solvents, soluble nyob rau hauv concentrated sulfuric acid, hydrofluoric acid, me ntsis soluble nyob rau hauv alkali thiab kub nitric acid. Nws tuaj yeem boiled rau ib lub sij hawm ntev kom yaj nyob rau hauv concentrated sulfuric acid thiab hydrofluoric acid. Nws reacts nrog molten sodium hydroxide los ua titanate. Thaum qhov kub thiab txias, nws tuaj yeem txo qis rau titanium los ntawm hydrogen, carbon, hlau sodium, thiab lwm yam, thiab hnov mob nrog carbon disulfide los ua titanium disulfide. Lub refractive index ntawm titanium dioxide yog qhov loj tshaj plaws nyob rau hauv cov xim dawb, thiab hom rutile yog 8. 70, 2.55 rau hom anatase. Txij li thaum ob qho tib si anatase thiab phaj titanium dioxide hloov mus rau hauv rutile ntawm qhov kub thiab txias, cov ntsiab lus melting thiab boiling ntawm phaj titanium thiab anatase yog qhov tsis muaj nyob. Tsuas yog rutile titanium dioxide muaj lub melting point thiab boiling point, lub melting point ntawm rutile titanium dioxide yog 1850 ° C, lub melting point nyob rau hauv huab cua yog (1830 ntiaj teb 15) ° C, thiab lub melting point ntawm oxygen enrichment yog 1879 ° C. , thiab lub melting point yog txuam nrog purity ntawm titanium dioxide. Qhov kub ntawm rutile titanium dioxide yog (3200 av 300) K, thiab titanium dioxide yog me ntsis volatile ntawm qhov kub siab no.
Txoj kev
Muaj titanium oxide sulfate yog yaj hauv dej thiab lim. Ammonia tau ntxiv rau precipitate ib gauntlet zoo li precipitate, thiab ces lim. Tom qab ntawd nws yog yaj nrog oxalic acid tov, thiab ces precipitated thiab lim nrog ammonia. Cov tau txais precipitate yog qhuav ntawm 170 ° C thiab ces ci ntawm 540 ° C kom tau cov ntshiab titanium dioxide.
Feem ntau ntawm lawv yog qhib-qhov mining. Titanium thawj ore beneficiation tuaj yeem muab faib ua peb theem: kev sib cais ua ntej (feem ntau siv sib nqus sib cais thiab lub ntiajteb txawj nqus sib cais), hlau sib nqus (sib nqus sib cais), thiab titanium sib cais (lub ntiajteb txawj nqus sib cais, sib nqus sib nqus, hluav taws xob sib cais thiab flotation method). Qhov txiaj ntsig ntawm titanium zirconium placers (feem ntau yog cov chaw ntug dej hiav txwv, ua raws li cov chaw hauv av) tuaj yeem muab faib ua ob theem: kev sib cais thiab kev xaiv. Xyoo 1995, Zhengzhou Comprehensive Utilization Research Institute ntawm Ministry of Geology thiab Mineral Resources tau txais cov txheej txheem sib nqus sib nqus, sib cais lub ntiajteb txawj nqus thiab cov kua qaub leaching kom tau txais txiaj ntsig rau qhov loj rutile mine hauv Xixia, Henan Province, uas tau dhau mus sim ntau lawm, thiab tag nrho cov ntsuas yog nyob rau theem ua hauv Suav teb.
siv
Nws yog siv los ua spectral tsom xam reagent, kev npaj ntawm high-purity titanium ntsev, pigments, polyethylene colorants, thiab abrasives. Nws kuj yog siv nyob rau hauv kev lag luam kws, capacitive dielectric, high-temperature resistant alloys, thiab high-temperature resistant titanium sponge manufacturing.
Nws yog siv los ua titanium dioxide, titanium daim txhuam cev, titanium alloy, dag rutile, titanium tetrachloride, titanium sulfate, potassium fluorotitanate, aluminium titanium chloride, thiab lwm yam. titanium dioxide tuaj yeem siv los ua cov xim dawb, dawb roj hmab, hluavtaws fibers. , coatings, vuam electrodes thiab rayon lub teeb-txo cov neeg ua hauj, yas thiab high-grade ntawv muab tub lim, thiab tseem siv rau hauv kev sib txuas lus khoom siv, metallurgy, luam ntawv, luam ntawv thiab dyeing, enamel thiab lwm yam departments. Rutile kuj tseem yog cov khoom siv ntxhia tseem ceeb rau kev ua kom zoo nkauj titanium. Titanium thiab nws cov alloys muaj cov khoom zoo xws li lub zog siab, tsis tshua muaj siab, corrosion kuj, kub tsis kam, tsis kub tsis kam, tsis muaj tshuaj lom, thiab lwm yam, thiab muaj cov haujlwm tshwj xeeb xws li roj nqus thiab superconductivity, yog li lawv tau siv dav hauv aviation, tshuaj lom neeg kev lag luam, lub teeb kev lag luam, navigation, kev kho mob, lub teb chaws tiv thaiv thiab marine kev pab cuam kev loj hlob thiab lwm yam kev lag luam. Ntau tshaj li 90% ntawm lub ntiaj teb cov titanium minerals yog siv los tsim titanium dioxide dawb pigments, thiab cov khoom no yog ntau thiab ntau lug siv nyob rau hauv cov xim, roj hmab, yas, ntawv thiab lwm yam lag luam.
kev ruaj ntseg
Khaws rau hauv qhov chaw txias, ventilated warehouse. Lub pob yog kaw. Nws tsis tuaj yeem khaws cia thiab sib xyaw nrog cov kua qaub.
Rutile mineral khoom yuav tsum tsis txhob tov nrog txawv teb chaws sundries nyob rau hauv tus txheej txheem ntawm ntim, cia thiab thauj. Lub hnab ntim khoom yuav tsum muaj corrosion-resistant thiab tsis yooj yim rau tawg. Lub hnab ntim ob txheej, sab hauv thiab txheej txheej yuav tsum sib phim, txheej sab hauv yog lub hnab yas lossis hnab ntaub (kraft ntawv kuj siv tau), thiab txheej txheej yog lub hnab woven. Qhov hnyav ntawm txhua pob yog 25kg lossis 50kg. Thaum ntim khoom, lub qhov ncauj ntawm lub hnab yuav tsum tau muab kaw kom nruj, thiab lub logo ntawm lub hnab yuav tsum ruaj khov, thiab cov ntawv sau yuav tsum meej thiab tsis ploj. Txhua batch ntawm cov khoom ntxhia yuav tsum tau nrog ib daim ntawv pov thawj zoo uas ua tau raws li qhov yuav tsum tau ua ntawm tus qauv. Kev khaws cov khoom ntxhia yuav tsum tau muab tso rau hauv cov qib sib txawv, thiab qhov chaw cia yuav tsum huv.
