· JVASP-11078· Ba2HoTaO6

Ba₂HoTaO₆ is a complex oxide ceramic compound containing barium, holmium, and tantalum—a perovskite-related double perovskite structure. This is a research-grade material primarily investigated for functional ceramic applications requiring high density and rare-earth incorporation, particularly in contexts where tantalum's chemical stability and holmium's magnetic or optical properties are leveraged.
