Potassium metavanadate

Potassium metavanadate (CAS 13769-43-2), also known as potassium vanadate, is an inorganic vanadium salt used primarily as a catalyst and catalyst precursor in industrial chemical processes.

Where is Potassium metavanadate used?

• Mining and metals: hydrometallurgical leaching circuits
• Catalyst precursor in sulfuric acid production via the contact process, where vanadium-based catalysts drive SO₂ oxidation
• Specialty glass and ceramics: colorant and modifier for controlled optical or thermal properties
• Corrosion inhibitor component in industrial treatment systems for metal surface protection
• It delivers controlled vanadium activity where precise oxidation state management is required.

Good to know: Technical grade is the standard commercial form, with purity typically specified at 98% or higher depending on end-use requirements. Handled according to strict industrial safety protocols for vanadium-based compounds.

Commercial specifications

• Purity typically 98% or higher
• Packaging from small laboratory quantities to bulk industrial supply
