The compound is obtained by reacting vanadium oxides (e.g. <sub>V2O5<\/sub>) with ammonia or ammonium salts in an aqueous environment. After precipitation and purification, the product is dried under controlled conditions, yielding a high-purity material.   <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Industrial applications<\/strong><\/h2>\n\n<h3 class=\"wp-block-heading\">1. <strong>production of catalysts<\/strong><\/h3>\n\n<p>Ammonium metavanadate is a source of vanadium in the synthesis of <sub>V2O5<\/sub>, a catalyst used in industry to produce sulfuric acid (contact process). Its oxidizing properties and thermal stability make it indispensable in industrial reactions for the conversion of <sub>SO2<\/sub> into <sub>SO3<\/sub>. <\/p>\n\n<h3 class=\"wp-block-heading\">2. <strong>modern functional materials<\/strong><\/h3>\n\n<p>It is used as a precursor of vanadium oxides nanoparticles for photocatalysts, electrochromes, gas sensors and as a dopant in semiconductors. Vanadium oxides with mesoporous structure obtained from ammonium metavanadate are used in humidity and ammonia sensors. <\/p>\n\n<h3 class=\"wp-block-heading\">3. <strong>dyes and pigments<\/strong><\/h3>\n\n<p>Vanadium stains glass and ceramics to shades of yellow, green and blue. Ammonium metavanadate is added to enamels, glazes and specialized heat-resistant paints. <\/p>\n\n<h3 class=\"wp-block-heading\">4. <strong>oxidation reactions in laboratories<\/strong><\/h3>\n\n<p>In organic chemistry, it is used as a selective oxidant, especially in the conversion of alcohols to aldehydes and ketones. Stability in aqueous media and ease of handling make it often used in qualitative and quantitative analysis. <\/p>\n\n<h3 class=\"wp-block-heading\">5. <strong>environmental photocatalysis<\/strong><\/h3>\n\n<p>Ammonium metavanadate, combined with titanium oxides (<sub>TiO2<\/sub>), is used to break down organic contaminants in water. It helps remove residues of pharmaceuticals, pesticides and phenols from industrial wastewater. <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Scientific and research significance<\/strong><\/h2>\n\n<p>Vanadium as a transition element is being intensively studied in a biological context. Its complexes have potential anticancer, antibacterial and hypoglycemic properties. Although ammonium metavanadate itself is not a drug, its derivatives are being used in studies of protein kinase inhibitors and as insulin analogs.  <\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Toxicological and health and safety aspects<\/strong><\/h2>\n\n<p>Store ammonium metavanadate in a dry, cool place, away from heat sources. Avoid inhalation of dust and skin contact. May be irritating to the respiratory system and skin. Personal protective equipment is recommended: masks, gloves and safety glasses.   <\/p>\n\n<ul class=\"wp-block-list\">\n<li>H302 &#8211; Harmful if swallowed<\/li>\n\n\n\n<li>H319 &#8211; Irritating to eyes<\/li>\n\n\n\n<li>H335 &#8211; May cause respiratory irritation<\/li>\n<\/ul>\n\n<h2 class=\"wp-block-heading\"><strong>Future applications<\/strong><\/h2>\n\n<p>Research worldwide is considering ammonium metavanadate as a component of modern sodium-ion and lithium-ion batteries. Vanadium layered structures show good conductivity and stability of charge cycles. <\/p>\n\n<p>Another promising area is the use of methavanadate as a carrier for enzymes in industrial biotechnology &#8211; particularly in the reaction of phenolic compounds in the biodegradation of lignin waste.<\/p>\n\n<h2 class=\"wp-block-heading\"><strong>Where to buy ammonium metavanadate?<\/strong><\/h2>\n\n<p>You can find high-quality <a href=\"\/?product_category=metawanadan-amonu\">ammonium metavanadate<\/a> at <a href=\"https:\/\/vichemic.pl\/en\/\">Vichemic<\/a> &#8211; available in the <a href=\"https:\/\/vichemic.pl\/en\/offers\/reagents-pure\/\">pure reagents<\/a> section.
