Mn- and Yb-Doped BaTiO-(NaBi)TiO Ferroelectric Relaxor with Low Dielectric Loss.

In this work, a Mn-and Yb-doped BaTiO-(NaBi)TiO ferroelectric relaxor was designed and prepared. The effects of Mn on the microstructures, dielectric and electrical properties of the ceramics were investigated. The X-ray structural analysis shows a perovskite structure.

AgMoO: an oxide solid-state Ag electrolyte.

AgMoO powders and micro-crystals were prepared at 400 °C for 24 h and 500 °C for 6 h using solid-state reactions. The AgMoO samples crystalized in a triclinic 1̄ space group with the cell parameters = 6.0972(1) Å, = 7.

Structure Evolution of NaO from Room Temperature to 500 °C.

NaO is one of the possible discharge products from sodium-air batteries. Here, we report the evolution of the structure of NaO from room temperature to 500 °C using variable-temperature neutron and synchrotron X-ray powder diffraction. A phase transition from α-NaO to β-NaO is observed in the neutron diffraction measurements above 400 °C, and the crystal structure of β-NaO is determined from neutron diffraction data at 500 °C.
