    Abstract Phase transitions in solid solutions generally tend to be broadened and diffused, often accompanied by the emergence of disordered phases. In this study, we report a contrasting result in a novel high-entropy compound, ilmenite-type (Mg0.2Mn0.2Co0.2Ni0.2Zn0.2)VO3, which exhibits a sharp structural phase transition accompanied by V–V dimerization, as well as an antiferromagnetic transition. (Mg0.2Mn0.2Co0.2Ni0.2Zn0.2)VO3 was obtained through high-pressure synthesis at 8 GPa and 1373 K for 1 h. At room temperature, the compound exhibited a triclinic ilmenite-type structure associated with V–V dimerization. Synchrotron X-ray diffraction (SXRD) and differential scanning calorimetry (DSC) measurements revealed that this compound underwent a structural transition to a rhombohedral phase at 510 K, concomitant with the disappearance of the V–V dimer structure. Furthermore, an antiferromagnetic transition was observed at 80 K through magnetic susceptibility and heat capacity measurements. The emergence of sharp structural and magnetic phase transitions, despite the high-entropy composition, represents a particularly noteworthy finding of this study.

    Abstract Semiconducting BaTiO 3 ‐based ceramics for positive temperature coefficient (PTC) thermistors have conventionally been sintered at ∼1400°C in a reducing atmosphere. In the present study, sintered BaTiO 3 ‐based semiconductor ceramics were obtained by exposing green compacts of BaTiO 3 powder to Na vapor in an Ar atmosphere. The Na vapor functioned as both a reducing agent and a sintering accelerator. Densification and grain growth of BaTiO 3 proceeded during heating at 800°C or higher. PTC thermistor properties with 1.9 orders of magnitude were observed at temperatures near the Curie temperature of BaTiO 3 (120°C). Contamination of sodium in the BaTiO 3 ‐based ceramics was rather small (∼ 0.2 wt%) and tiny areas containing Na were found in some of the fracture surfaces of ceramics.

    The first experimental realization of KBaBi, a ternary Zintl compound theoretically predicted to exhibit promising thermoelectric properties, is reported. Single crystals were successfully synthesized from constituent elements, and structural analysis revealed that KBaBi crystallizes in a hexagonal ZrBeSi‐type structure (space group P63/mmc, Z = 2) with lattice parameters a = 6.0884(5) Å and c = 7.4868(6) Å at 300 K. In this structure, Ba and Bi atoms form planar honeycomb lattices stacked along the c‐axis with K‐atom layers sandwiched between them. Notably, K atoms exhibit remarkably large thermal vibrations, with the equivalent isotropic atomic displacement parameter approximately twice those of Ba and Bi atoms in the temperature range of 100–300 K, suggesting potential "rattling" behavior beneficial for thermoelectric performance. Transport measurements on a sintered polycrystalline sample (70% relative density) revealed electrical resistivity increasing from 3.89 to 8.56 mΩ cm and positive Seebeck coefficients ranging from 48.8 to 88.1 µV K−1between 296–486 K, indicating that KBaBi is a p‐type narrow‐gap semiconductor.
