· Y2 Ta6 O18

Y₂Ta₆O₁₈ is a mixed-metal oxide ceramic compound containing yttrium and tantalum in a complex perovskite-related structure. This material is primarily of research and exploratory interest, studied for its potential in high-temperature structural applications and as a functional ceramic where the combination of rare-earth (yttrium) and refractory metal (tantalum) oxides may offer enhanced thermal stability, oxidation resistance, or electronic properties relative to simpler oxide systems.
