Summary: The mechanical properties of a ZrB2-SiC-G ultrahigh temperature ceramic were evaluated through ultrahigh-temperature uniaxial tension and in-situ monitoring of fracture behavior. The material exhibited inconsistent property degradation at temperatures between 1200-2000°C. Tensile modulus degradation was significant at 1400°C, while strength degradation occurred mainly at 1800°C. Elastic fracture was observed at 1200, 1400, and 1600°C, but interrupted at 1800 and 2000°C. Severe plasticity occurred in this temperature range, reducing the material's bearing capacity. The brittle-to-ductile transition was confirmed through in-situ observation of fracture behavior at 1200-2000°C. Finally, a constitutive relation of modulus and strength was developed, considering the effect of temperature, which can be applied in finite element models for the structural design of UHTC-based thermal protection systems.

Summary: The small-signal dielectric and piezoelectric coefficients of paper-derived sodium potassium niobate (KNN) were compared with conventionally prepared samples. The results showed similar functional properties and crystal structure between the two, but a decrease in the temperature-dependent inter-ferroelectric phase transition temperature was observed in the paper-derived KNN, possibly due to structural and microstructural defects. Optimizing suspension chemistry and sintering conditions is crucial to enhance the functional response of paper-derived KNN. Paper-derived ceramic processing is a cost-effective technology that can be used to fabricate other electroceramics with various porosities, sizes, and complex geometries.

Summary: In this work, <001>-oriented Pb(In1/2Nb1/2)O-3-Pb(Sc1/2Nb1/2)O-3-PbTiO3 textured ceramics were fabricated by the template grain growth method. The electromechanical properties of these ceramics under different external fields were characterized and analyzed. The results showed that the dielectric constants of all textured ceramics increased with uniaxial prestress and hydrostatic pressure, but decreased with the increase of d.c. bias electric field. The textured ceramic with 3 vol. % BT templates exhibited the best stability under external fields, with less than 2% change in the electromechanical coupling factors under hydrostatic pressure increase to 100 MPa.

Summary: We propose an innovative strategy based on defect chemistry to achieve a giant strain of 1.12% in lead-free Bi0.5Na0.5TiO3 (BNT)-based ceramics by forming a defect-engineered morphotropic phase boundary. The incorporation of the hypothetical perovskite BaAlO2.5 with oxygen defect into BNT leads to strongly polarized directional defect dipoles, resulting in a strong pinning effect after aging. The large asymmetrical strain is mainly attributed to the aligned defect dipoles along the crystallographic [001] direction destroying the long-range ordering of the ferroelectric and promoting reversible phase transition and polarization rotation.

Summary: We developed a seed-passivated texturing process using Ba(Zr, Ti)O3 microplatelet templates to fabricate textured PZT ceramics. This process promotes template-induced grain growth in titanium-rich PZT layers and enables the desired composition through interlayer diffusion of zirconium and titanium. The textured PZT ceramics exhibited excellent properties, with Curie temperatures of 360 degrees C, piezoelectric coefficients d(33) of 760 picocoulombs per newton and g(33) of 100 millivolt meters per newton, and electromechanical couplings k(33) of 0.85. This study overcomes the challenge of fabricating textured rhombohedral PZT ceramics by suppressing the chemical reaction between PZT powder and titanate templates.

Summary: The authors designed NaNbO3 based ceramics to achieve a reversible phase transformation between antiferroelectric and ferroelectric phases, resulting in a well-defined double hysteresis loop in the P-E hysteresis curve. NaNbO3 is a lead-free antiferroelectric material with potential applications in energy storage capacitors, solid-state cooling, and displacement transducers. A new strategy of reducing the oxygen octahedral tilting angle is proposed to stabilize the antiferroelectric phase of NaNbO3, and its effectiveness is confirmed through experimental characterization. The resulting ceramic exhibits highly reversible phase transitions and improved properties compared to pure NaNbO3.

Summary: This research focuses on the electrical and dielectric properties of BaTiO3-based compounds and the mechanism of oxygen vacancy conduction. It is found that B-site dopants effectively reduce conductivity by inhibiting the migration of oxygen vacancies. Zn, in particular, has a stronger ability to inhibit oxygen vacancy migration due to both thermodynamic and kinetic effects. This work provides new insights for designing efficient and durable medium-temperature solid oxide capacitor devices.

Summary: The origins of unipolar strain, strain hysteresis, and remnant strain in Mn-modified BF-BT ceramics near the pseudo-cubic and rhombohedral (PC-R) phase boundary were investigated using high-energy synchrotron X-ray diffraction. It was found that the largest unipolar strain occurred at the composition with a single pseudo-cubic phase, due to the synergetic contributions from reversible phase transition, non-180 degrees domain switching, and lattice distortion. The phase boundary composition exhibited irreversible phase transition, with the unipolar strain attributed to lattice distortion. The lowest strain hysteresis and remnant strain were observed in BF-BT ceramics with rhombohedral phase, as reversible lattice distortion dominated the strain level.
