· JVASP-9796· Ba3MgNb2O9

Ba3MgNb2O9 is a complex oxide ceramic composed of barium, magnesium, and niobium—a perovskite-related compound typically studied for its dielectric and ferroelectric properties. This material belongs to the family of niobate-based ceramics and is primarily of research and development interest rather than established high-volume production. The compound is investigated for potential applications in microwave devices, capacitors, and resonators where controlled dielectric response is critical, as well as in multiferroic systems where magnetic and electric properties may be coupled.
