'''Vanadin(V)oxid''' eller '''vanadinpentoxid''' är en [[kemisk förening]] av metallen [[vanadin]] och [[syre]] med [[kemisk formel|formeln]] V<sub>2</sub>O<sub>5</sub>.<br />
<br />
==Framställning==<br />
Vanadinpentoxid framställs ur vanadinmalm genom att behanda den med [[natriumkarbonat]] (Na<sub>2</sub>CO<sub>3</sub>) vilket ger [[salter]]na [[natriummetavanadat]] (NaVO<sub>3</sub>) och [[natriumortovanadat]] (Na<sub>3</sub>VO<sub>4</sub>). När [[svavelsyra]] tillsätts lösningen fälls olika oxider av vanadin ut när [[pH-värde]]t har fallit till runt 2. Utfällningen värms upp till 690&nbsp;°C vilket ger vanadinpentoxid.<br />
<br />
==Användning==<br />
Den största mängden vanadinpentoxid används vid framställning av olika [[stål]]-[[legering]]ar. Den [[Redox|reduceras]] med [[kol]] eller [[koks]] i [[masugnsprocess]]en på samma sätt som [[järn(III)oxid]].<br />
<br />
Vanadinpentoxid används också vid tillverkningen av [[svavelsyra]]. Det är nämligen en effektiv [[katalysator]] för att oxidera [[svaveldioxid]] till [[svaveltrioxid]].<br />
:<math>\rm 2\ SO_2 + O_2 \leftrightharpoons 2\ SO_3</math><br />
<br />
Andra tillämpningar är som [[sensor]]material i [[Bolometer|bolometrar]] och [[Värmekamera|värmekameror]].<br />
