ChemInform Abstract: First 14‐Layer Twinned Hexagonal Perovskite Ba 14 Mn 1.75 Ta 10.5 O 42 : Atomic‐Scale Imaging of Cation Ordering

Polycrystalline Ba 14 Mn 1.75 Ta 10.5 O 42 (BMT) is prepared by calcination of a stoichiometric mixture of BaCO 3 , MnCO 3 , and Ta 2 O 5 (Al 2 O 3 crucible, 1473 K, 8 h), pelletizing, and further firing in air (1773 K, 12‐24 h).
