Silver tungstate is an inorganic tungstate with the chemical formula Ag2WO4. It has been applied in various fields such as photoluminescence, antibacterial action, ozone gas sensors and humidity sensors.[2][3] It is also used in the electronic and chemical industries, and also used in proteomics research.[4]
Phases
Silver tungstate occurs in three polymorphic phases: orthorhombic (α), hexagonal (β) and cubic (γ).[2] α-silver tungstate is thermodynamically stable, while β- and γ-silver tungstate are metastable.[5]
Synthesis
Silver tungstate is synthesised through the following reaction between silver nitrate and sodium tungstate, producing sodium nitrate as a byproduct:[2]
- 2 AgNO3 + Na2WO4 → Ag2WO4 + 2 NaNO3
