Sodium metavanadate
Sodium metavanadate is the inorganic compound with the formula NaVO3. It is a yellow, water-soluble solid.
Sodium metavanadate is a common precursor to other vanadates. At low pH it converts to sodium decavanadate. It is also precursor to exotic metalates such as 5-, 4-, and 5-.Minerals
Sodium metavanadate occurs as two minor minerals, metamunirite and a dihydrate, munirite. Both are very rare, metamunirite is now known only from vanadium- and uranium-bearing sandstone formations of central-western USA and munirite from Pakistan and South Africa.
