SnWO4

Tin tungstate (SnWO₄) is an inorganic ceramic compound combining tin and tungsten oxides, belonging to the family of metal tungstates used primarily in research and specialized applications. It is investigated for photocatalytic and optoelectronic applications, particularly in water treatment and environmental remediation where its band gap and crystal structure enable light-driven reactions. The material is less established in mainstream industrial use than commercial alternatives like TiO₂, but represents a promising candidate in the tungstate family for applications requiring tunable electronic properties or enhanced catalytic performance under visible light.
