Metallurgical Product Description
Vanadium pentoxide, IUPAC lub npe yog vanadium (V) oxide, yog oxide ntawm vanadium (V), thiab nws cov tshuaj formula yog V2O5. Nws poob oxygen thiab decomposes thaum rhuab. Nws tuaj yeem siv los ua ib qho catalyst hauv kev lag luam tshuaj. Qhov tseem ceeb tshaj plaws yog txhawm rau txhawm rau txhawm rau hloov pauv ib kauj ruam ntawm sulfur dioxide rau hauv sulfur trioxide hauv kev lag luam sulfuric acid.
Vanadium ({0}}) nyob rau hauv vanadium pentoxide muaj lub siab tshaj plaws oxidation xeev thiab muaj amphoteric thiab oxidizing zog. Cov tshuaj no yog soluble hauv hydrochloric acid thiab tso tawm cov roj chlorine, uas txo qis rau IV + oxidation xeev.
Vanadium pentoxide vapor yog tshuaj lom thiab insoluble hauv dej, tab sis nws tsim vanadium acid, ua rau cov kua qaub. Tsis tas li ntawd, txawm hais tias nws yog insoluble nyob rau hauv sulfuric acid thiab nitric acid, nws yog soluble nyob rau hauv alkaline aqueous kua.

kev npaj ntawm cov khoom
Ua ntej, cov zaub mov uas muaj vanadium raug kho nrog sodium carbonate los tsim sodium metavanadate, thiab tom qab ntawd sulfuric acid yog siv los tswj pH rau 2-3, precipitate, thiab tom qab ntawd rhuab mus rau 690 degree thiab melted kom tau crude vanadium pentoxide.
Cov khoom tseem ceeb ntawm cov tshuaj tiv thaiv ntawm cov hlau nplaum vanadium thiab cov pa ntau dhau yog vanadium pentoxide, tab sis nws feem ntau muaj lwm yam tsis zoo oxide impurities ntawm vanadium. Hauv chav kuaj, vanadium pentoxide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv decomposition ntawm ammonium metavanadate ntawm 200 degree.
kev thov ntawm cov khoom
Vanadium pentoxide tuaj yeem siv los ua tshuaj ntsuam xyuas cov tshuaj tiv thaiv, catalysts, thiab UV blockers rau iav thiab cov tsim tawm.
Vanadium pentoxide tuaj yeem siv los ua ib qho catalyst rau sulfuric acid ntau lawm thiab cov organic synthesis thiab tseem siv rau hauv ceramics thiab iav industries.
Vanadium pentoxide tuaj yeem siv rau hauv kev lag luam metallurgical los tsim ferrovanadium alloy hlau, thiab hauv kev lag luam ammonia synthesis rau decarburization, desulfurization, thiab catalyst. Nws yog siv los ua cov khoom siv xim rau luam ntawv thiab dyeing thiab ceramics, ua cov khoom siv tiv thaiv corrosion rau cov khoom siv los tiv thaiv corrosion hauv cov nroj tsuag petrochemical, thiab ua cov khoom siv raw rau kev npaj cov tshuaj vanadium.
