Sodium metavanadate is used as an analytical reagent and mordant. It is also found to be useful in the photography industry and the pharmaceutical industry. In addition to this, it is used in the making of vanadium alloy and vanadium catalyst.
Vanadium is a metallic element that occurs in six oxidation states and numerous inorganic compounds. Some of the more important compounds are vanadium pentoxide (V2O5), sodium metavanadate (NaVO3), sodium orthovanadate (Na3VO4), vanadyl sulfate (VOSO4), and ammonium vanadate (NH4VO3). Vanadium is used primarily as an alloying agent in steels and non-ferrous metals (ATSDR, 1990). Vanadium compounds are also used as catalysts and in chemical, ceramic or specialty applications.
Sodium metavanadate (SMV) is a vanadium salt that can be used as a corrosion inhibitor with good inhibition efficiency (98%) at 200 ppm. It can be used in the protection of carbon steel.
