· JVASP-10999· Ba2TmNbO6

Ba2TmNbO6 is a double perovskite ceramic compound containing barium, thulium, and niobium. This is a research-phase material studied for its potential in advanced functional ceramics, particularly for applications requiring high stiffness and thermal stability in demanding environments. Double perovskites of this family are investigated for dielectric, ferroelectric, and structural applications where the ordered arrangement of cations on the B-site provides tunable electrical and mechanical properties.
