· MoTaO3

MoTaO3 is a mixed-metal oxide ceramic compound combining molybdenum and tantalum oxides in a perovskite-related crystal structure. This material is primarily of research interest rather than a widespread industrial ceramic, explored for its potential in high-temperature applications, electronic devices, and catalytic systems due to the refractory nature of both constituent elements. The combination of molybdenum and tantalum oxides may offer tailored thermal stability, electrical properties, or chemical reactivity compared to single-component oxides, though specific engineering applications remain limited to specialized or emerging sectors.
