Sodium metavanadate is a yellow solid which is soluble in water. Its use is limited to its hygroscopic property. 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.^[1]
