Vanadium Pentoxide hmoov

Vanadium pentoxide hmoov (V2O5) yog ib qho tseem ceeb ntawm cov khoom siv raw nrog lub cev thiab tshuaj lom neeg zoo heev. V2O5 yog purity siab thaum nws purity ntau dua 99.5%. Nws yog cov khoom siv tseem ceeb rau kev npaj cov khoom siv high-purity hlau vanadium thiab high-purity vanadium compounds.

V205 hmoov

Nyob rau hauv xyoo tas los no, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, cov tswv yim tawm tswv yim zoo xws li cov roj teeb tag nrho-vanadium redox txaus rau lub zog loj cia hauv photovoltaic, cua zog thiab lwm lub zog tshiab thiab microgrid teb, kev ua haujlwm siab ntawm lithium-ion roj teeb. Raws li lithium vanadate series thiab siab tshaj vanadium-raws li alloys tau tshwm sim. Kev lag luam tau nce siab dua qhov yuav tsum tau ua rau purity ntawm vanadium cov khoom, ua rau muaj kev xav tau ntau ntxiv rau high-purity vanadium pentoxide.

1. Cov khoom siv hluav taws xob cia

(1) Vanadium ntws roj teeb

Vanadium flow batteries siv cov tshuaj tiv thaiv redox ntawm vanadium ions nyob rau hauv ntau lub xeev valence kom ua tiav kev sib hloov ntawm cov tshuaj zog thiab hluav taws xob hluav taws xob. Vanadium electrolyte yog cov tshuaj aqueous ntawm vanadium sulfate (VOSO4), uas yog cov khoom siv hluav taws xob hluav taws xob. Lub purity ntawm VOSO4 yuav tsum siab tshaj 99.9% (kom tsis txhob muaj kev cuam tshuam ntawm impurity ions ntawm lub roj teeb). VOSO4 yog npaj los ntawm high-purity V2O5 siv txoj kev txo cov tshuaj.

(2) Vanadium-based hydrogen cia cov ntaub ntawv

Vanadium (V)-raws li cov kua hydrogen cia alloy muaj lub cev-centered cubic (BBC) qauv. Qhov theoretical hydrogen absorption muaj peev xwm ncav cuag 3.8%, uas loj dua AB5 hom (1.4%) thiab AB hom (1.86%). Nws tuaj yeem ua tiav sai sai ntawm chav tsev kub. Muaj peb lub tshuab tseem ceeb rau kev nqus thiab tso tawm hydrogen: V-Ti-Fe, V-Ti-Mn thiab V-Ti-Cr. Ntawm lawv, V43.5Ti49Fe7.5 muaj qhov loj tshaj plaws hydrogen nqus peev xwm, ncav cuag 3.9%.

Vanadium Pentoxide

Vanadium Pentoxide hmoov

Vanadium catalysts yog dav siv nyob rau hauv sulfuric acid ntau lawm, synthesis ntawm organic tshuaj raw cov ntaub ntawv nyob rau hauv cov roj av kev lag luam, thiab flue gas desulfurization thiab denitrification kev kho mob. Cov khoom xyaw nquag ntawm vanadium catalysts feem ntau siv hauv kev lag luam muaj xws li vanadium oxides, chlorides, complexes, thiab lwm yam Catalysts uas muaj high-purity V2O5 raws li lub ntsiab tivthaiv yog zoo nyob rau hauv yuav luag tag nrho cov oxidation tshuaj.

Cov catalyst feem ntau muaj 5% mus rau 10% V2O5, thiab tseem muaj K2O lossis Na2O kom nce kev ua haujlwm ntawm vanadium catalyst. Diatomaceous lub ntiaj teb yog siv los ua tus nqa khoom kom nce thaj tsam ntawm cov catalyst active tivthaiv nyob rau hauv kev sib cuag nrog cov roj. Qee cov vanadium catalysts kuj muaj antimony oxide, tin oxide, aluminium oxide thiab hlau oxide. Tam sim no, muaj ntau tshaj 20 vanadium catalyst manufacturers nyob rau hauv kuv lub teb chaws, muaj peev xwm ntau lawm ntau tshaj 20 kt / a.
