Vanadate, potassium - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | potassium metavanadate, colorless to light green crystalline solid, thicker than water. Contact may irritate the skin, eyes, and mucous membranes, and ingestion may be toxic. It can be used in the manufacture of dyes, inks and laundry compounds. |
| Application | potassium metavanadate can be used as corrosion inhibitor and scale inhibitor, and is widely used in chemical fertilizer industry, glass ceramic industry and pharmaceutical industry. It is also used in plastic, enamel, ceramic pigment production process, mainly for industrial gas desulfurization and H2S adsorption elimination. |
| toxic | highly toxic, potentially fatal by inhalation, swallowing, or transdermal absorption. Avoid any skin contact. Effects of exposure or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. The run-off of fire fighting or dilution water may be corrosive and/or toxic and cause contamination. |
| Application | used as catalyst, mordant, etc. used as analytical reagent |
| category | toxic substances |
| toxicity grade | highly toxic |
| flammability hazard characteristics | ; vanadium Oxide and potassium oxide smoke generated in fire scene|
| storage and transportation characteristics | The warehouse is ventilated and dried at low temperature; It is stored and transported separately from combustible materials, reducing agents and food |
| extinguishing agent | carbon dioxide, sand |
| Occupational Standard | TLV-TWA0.05 mg (vanadium pentoxide)/m3; STEL0.1 mg (vanadium pentoxide)/M3 |
