High-purity vanadium compounds for SCR and sulfuric acid catalyst manufacture.
Vanadium pentoxide is the active component in selective catalytic reduction catalysts, which convert nitrogen oxides to nitrogen and water across power generation, marine engines and industrial furnaces. It is also the active phase in contact catalysts used for sulfuric acid manufacture.
In both cases the catalyst manufacturer is buying activity and service life, and both are sensitive to what arrives with the vanadium. Alkali metals, iron and other trace contaminants act as catalyst poisons or promote unwanted side reactions.
Riverside supplies vanadium feedstocks with the consistency catalyst production requires, and can hold a specification across repeat orders rather than shipping to a broad commercial grade.

Vanadium is the active catalytic species. Everything else in the feedstock is either inert or a poison, which is why trace-level consistency matters more here than headline assay.
