· JVASP-49669· Mg2TaSbO6

Mg₂TaSbO₆ is a complex mixed-metal oxide ceramic belonging to the pyrochlore or perovskite-derivative family, containing magnesium, tantalum, and antimony in a structured lattice. This compound is primarily studied in materials research contexts for potential applications in functional ceramics, particularly where high dielectric properties, thermal stability, or ionic conductivity are desired. The tantalum and antimony components confer chemical stability and potentially useful electronic or ferroelectric characteristics compared to simpler oxide alternatives.
