Sodium metavanadate is the inorganic compound with the formula NaVO3.[1] It is a yellow, water-soluble solid. Its natural forms include mineral metamunirite (anhydrous) and a dihydrate, munirite. Both are very rare, metamunirite is now known only from V- and U-bearing sandstone formations of central-western USA and munirite from Pakistan and South Africa.[2]
