    • openAccess   Field enhanced bulk conductivity of acceptor-doped BaTi1−xCaxO3−x ceramics 

      Masó, Nahum; Prades Tena, Marta; Beltrán Mir, Héctor; Cordoncillo, Eloisa; Sinclair, Derek C.; West, Anthony R. American Institute of Physics (2010)
      The electrical properties of Ca-doped BaTiO3 are very different when Ca substitutes onto Ba or Ti sites. The p-type semiconductivity of Ti-substituted ceramics increases reversibly by one to two orders of magnitude under ...

    • closedAccess   Polymorphism and Dielectric Properties of Nb-Doped BaTiO3 

      Masó, Nahum; Beltrán Mir, Héctor; Cordoncillo, Eloisa; Sinclair, Derek C.; West, Anthony R. Wiley (2008-01)
      A working subsolidus phase diagram for the system BaTiO3–Ba5Nb4O15 has been determined by firing sol–gel-synthesized samples over a range of temperatures. The main difference from previous diagrams is the greater extent ...
