Description

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. It delivers controlled vanadium activity in systems where precise oxidation state management is required for process efficiency. In the mining and metals sector, it is used in hydrometallurgical leaching circuits. The compound supports selective metal extraction from ores and process streams. It functions as a catalyst precursor in the production of sulfuric acid via the contact process, where vanadium-based catalysts drive SO₂ oxidation. Specialty glass and ceramic manufacturers use it to introduce vanadium as a colorant and modifier in formulations requiring controlled optical or thermal properties. It also serves as a corrosion inhibitor component. These industrial treatment systems target metal surface protection across various manufacturing environments. Potassium metavanadate is available as a crystalline powder or granular solid for diverse applications. Technical grade is the standard commercial form, with purity levels typically specified at 98% or higher depending on end-use requirements. Packaging ranges from small laboratory quantities to bulk industrial supply. Specification sheets are aligned to catalyst and reagent-grade applications to ensure consistent performance. This material is handled according to strict industrial safety protocols for vanadium-based compounds. Contact us for supply of Potassium metavanadate Request Quote
