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.[1][2] It is also used in the electronic and chemical industries, and also used in proteomics research.[3]
Phases
Silver tungstate occurs in three polymorphic phases: orthorhombic (α), hexagonal (β) and cubic (γ).[1] α-silver tungstate is thermodynamically stable, while β- and γ-silver tungstate are metastable.[4]
Synthesis
Silver tungstate is synthesised through the following reaction:[1]
