Na4WO4

Sodium tungstate (Na₄WO₄) is an inorganic ceramic compound containing tungsten oxide in an alkali matrix, typically encountered as a powder or crystalline solid in industrial chemistry. This material is primarily used in specialty chemical applications including corrosion inhibitors, catalytic supports, and flame-retardant formulations, where tungsten's high density and oxidation resistance provide functional benefits. While not a mainstream structural ceramic, sodium tungstate is valued in niche applications where tungsten compounds' chemical stability and thermal properties are leveraged; it is also of interest in materials research for potential use in advanced ceramics, pigments, and electrochemical devices.
