Fabrication and microstructure of directionally solidified SrCe1−xYxO3−δ (x=0.1, 0.2) high temperature proton conductors

Progress on the development of H-concentration probes in eutectic lead–lithium: Synthesis and characterization of electrochemical sensor materials

“…The specimens show a single phase of the perovskite-type and good agreement with bibliography data [17][18][19][20]. Although some minor impurities are present (marked in Fig.…”

“…This was achieved by mixing SrCO 3 , CeO 2 and Y 2 O 3 (99, 99.5 and 99.9% Alfa Aesar) together in the appropriate stoichiometric ratios as described in Ref. [19].…”

Phase transitions in the H+-conducting perovskite ceramics by the quasi-elastic neutron and high-pressure Raman scattering

“…O 3 doped or modified by various elements (Y, Yb etc.) are then widely investigated both theoretically and experimentally by various techniques [1][2][3][4][5][6][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Among the large family of conducting perovskites, the alkaline earth zirconates are chemically more stable and stronger in mechanical strength than cerates or titanates ceramics and thus seem to be better for the application field [1].…”

Processing and mechanical behavior at elevated temperatures of directionally solidified proton conducting perovskites

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Most of the studies have been performed on sintered or hot-pressed compounds. However, directionally solidified materials grown from the melt through a controlled system have been shown to exhibit properties superior to their polycrystalline counterparts, [15][16][17] due to the unique microstructures that can be created during directional solidification. Among the various directional solidification techniques, the laser-heated floating zone (LHFZ) has been proved to be a fast and effective technique that produces materials in a variety of processing conditions and shapes.…”
