What is Potassium metavanadate?

Chemical properties

colorless crystal(s); -200mesh with 99.9% purity; there are also K3VO4, 14293-78-8, and K4V2O7, 14638-93-8 [CRC10] [CER91]

The Uses of Potassium metavanadate

Employed as corrosion inhibitors and anti-scaling agents. Used widely in chemical fertilizer industries, glass and ceramic industries, pharmaceutical industries. Also used in the process of pigment production for plastics, enamels, ceramics. Used for industrial gas desulphuration and H2S adsorption and elimination.

General Description

A colorless to pale green colored crystalline solid. Denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion. Used to make dyes, inks and laundry compounds.

Air & Water Reactions

Soluble in water.

Reactivity Profile

Salt.

Health Hazard

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
