Tungsten Trioxide CAS 1314-35-8 yog dab tsi?

Lub teeb daj hmoov. Insoluble nyob rau hauv dej thiab dav inorganic acids, soluble nyob rau hauv kub alkali tov, me ntsis soluble nyob rau hauv hydrofluoric acid. Tungsten trioxide yog ib qho tseem ceeb hauv kev lag luam ntawm kev tsim cov tungsten los ntawm tungsten ore. Cov txheej txheem smelting muaj ob kauj ruam: thawj kauj ruam yog kho cov tungsten ore nrog alkali kom tau WO3, thiab tom qab ntawd txo cov tungsten trioxide nrog carbon lossis hydrogen kom tau cov hlau tungsten: WO3 + 3H2 → W + 3H2O2WO3 + 3C → 2W + 3CO2

Daim ntawv thov

1. Kev tsim cov siab melting point alloys thiab cemented carbide. Tungsten trioxide yog siv los ua cov alloys thiab cemented carbides nrog cov ntsiab lus melting siab uas muab kev ruaj ntseg hauv qhov kub thiab txias.

2. Kev tsim cov tungsten hlau thiab cov khoom siv hluav taws kub. Nws kuj tseem siv rau hauv kev tsim cov tungsten hlau thiab cov ntaub ntawv fireproofing, ua tsaug rau nws cov khoom zoo thaum tshav kub kub-resistant.

3. Cov khoom siv hluav taws xob. Tungsten trioxide yog ib qho tseem ceeb ntawm cov khoom siv electrochromic uas tuaj yeem siv rau hauv thaj chaw xws li cov iav dimming ntse, cov ntaub ntawv qhia, cov ntsuas hluav taws xob qis, cov pa roj carbon monoxide sensors, spacecraft anti-reflective coatings thiab infrared emission regulation.

4. Catalyst. Nws yog ib qho tseem ceeb catalytically active khoom uas yuav siv tau raws li lub ntsiab catalyst los yog ib tug auxiliary catalyst. Nws yog dav siv hauv hydrodesulfurization, SCR denitrification, photocatalysis, thiab lwm yam.
Solar cells thiab kev siv electrochemical. Tungsten trioxide kuj tau siv dav hauv lub hnub ci hlwb, electrochemistry, photoluminescence, teb emission thiab lwm yam.

5. Cov khoom siv photochromic. Tam sim no nws yog ib qho ntawm cov khoom zoo tshaj plaws photochromic nyob rau hauv lub ntiaj teb no thiab muaj daim ntawv thov tus nqi hauv cov teb xws li kev tiv thaiv, kho kom zoo nkauj, thiab khaws cov ntaub ntawv.

6. Dimmable iav. Raws li daim ntawv thov ntawm cov khoom siv zaj duab xis electrochromic, tungsten trioxide yog ua raws li cov txheej txheem laminated iav uas twb muaj lawm, thiab cov yeeb yaj kiab dimming tau ruaj khov ntawm ob daim ntawm cov iav float.

7. Cov ntaub thaiv npog. Raws li cov khoom siv tiv thaiv, tungsten trioxide muaj qhov zoo ntawm kev tiv thaiv zoo, zoo breathability thiab washability. Nws tuaj yeem ua rau cov khaub ncaws hlau fiber ntau hluav taws xob thiab tuaj yeem siv rau hauv kev kho mob tiv thaiv qhov chaw.
Roj cell carrier. Tungsten trioxide tuaj yeem hloov pauv cov pa roj carbon monoxide raws li cov cab kuj ntawm cov roj hlwb, thauj cov hlau muaj txiaj ntsig, thiab tsim Pt / WO3 / C catalyst, yog li txhim kho corrosion kuj ntawm cov catalyst thiab thaum kawg ua rau kev pab cuam lub neej ntawm catalyst.

8. Npaj cov khoom tiv thaiv. Raws li cov khoom rhiab heev, tungsten trioxide muaj qhov zoo ntawm cov qauv yooj yim, tus nqi qis, thiab siab rhiab heev. Nws tuaj yeem siv los npaj cov khoom tiv thaiv, xws li NO2 gas sensors thiab H2S gas sensors.
