Co-doping of yttrium doped mixed barium cerate/zirconate perovskite (BCZY) with small amounts of Pr (BCZYP) substantially increases electrical conductivity while retaining structural and chemical stability. BCZYP is predominantly a proton conductor at temperatures up to 600-650 ̊C, whereas it is a mixed proton/oxide ion/electron conductor at higher temperatures. The co-doped BCZYP perovskite can...

A ferroelectric heater under A.C. field was demonstrated by using lead zirconate titanate and barium titanate ceramics. The temperature of the ceramics was increased from room temperature to its curie temperature of phase transition under an A.C. field. The heating characteristics greatly depend on the compositions of ceramics. It is proposed that the heating behavior is related to the domain s...

The bias-field-dependent dielectricity of ferroelectric thin films is studied by use of a multilayer model capable of modeling saturated and unsaturated hysteresis behavior under arbitrary fields. The simulated minor hysteresis loops at different bias fields are used to calculate the variation of dielectric permittivity with the bias field. The -E loops show asymmetric shifting along the field ...

The elastic properties of 0, 10, 15, and 20 mol% yttrium-doped barium zirconate (BZY0, BZY10, BZY15, BZY20) at the operating temperatures protonic ceramic fuel cells were evaluated. proposed measurement method for low sinterability materials could accurately determine sonic velocities small-pellet-type samples, determined based on these velocities. Young’s modulus BZY20 was 224, 218, 209 GPa °C...
