Silver niobate (AgNbO₃) is a mixed-valence perovskite-related oxide semiconductor composed of silver and niobium cations in an oxide framework. While primarily a research material rather than a commodity engineering material, it is studied for its ferroelectric and photocatalytic properties, positioning it within the broader family of functional ceramics and complex oxides. AgNbO₃ is of particular interest in photocatalysis for environmental remediation, ferroelectric device applications, and optoelectronic research, where its narrow bandgap and ion-migration behavior offer potential advantages over conventional titanates and tantalates, though its silver content and stability under operating conditions present engineering trade-offs compared to more established alternatives.
