· Na4 W1 O4

Na4W1O4 is an inorganic oxide compound combining sodium and tungsten—a ceramic material belonging to the tungstate family of compounds. This composition represents a research-phase material studied primarily for photocatalytic and electrochemical applications rather than a conventional engineering ceramic in widespread industrial use. The tungstate family is notable for its potential in environmental remediation and energy conversion, where tungsten oxides offer advantages in photocatalysis and ion-intercalation chemistry compared to more common titania-based alternatives.
