Sr0.61Ba0.39Nb2O6 (SBN61) ceramic fibers with a high [001] texture were fabricated by a combination of alginate gelation method and templated grain growth process using acicular Ba2NaNb5O15 (BNN) template particles. The rod-like BNN template particles were prepared by molten salt synthesis method with salt/powder ratio of 2 giving the highest aspect ratio. Fibers were drawn from alginate based slurries without or with 10 wt% BNN template particles. Increasing sintering temperature and time were found to increase the texture. Textured SBN61 bulk ceramics with dimensions in cm scale were fabricated by wet packing a limited number of grain oriented green fibers and sintering the green bulk to obtain a dense, textured bulk ceramic through templated grain growth. A maximum texture fraction, f, of 0.91 was obtained, as measured by Lotgering factor. Increased remnant polarization and electromechanical properties were obtained as a result of this preferred grain orientation. (C) 2016 Elsevier Ltd. All rights reserved.

Cold sintering ZnO based varistor ceramics with controlled grain growth to realize superior breakdown electric field

Xuetong Zhao, Jie Liang, Jianjie Sun, Jing Guo, Sinan Dursun, Ke Wang, Clive A. Randall

Summary: The study presents a strategy to fabricate dense ZnO-based ceramics with controlled grain growth and thin grain boundaries using cold sintering process (CSP). By utilizing CSP, the sintering temperature of ZnO-based ceramics significantly decreases, and Bi-rich intergranular films can be observed along grain boundaries, leading to superior performances of the ceramics. This work demonstrates that CSP is a promising technique for designing new submicron-/nano-ceramics with improved electrical properties.

Enhancement of the electrocaloric effect in PbZr0.7Ti0.3O3 ceramics via La doping: Driven by phase co-existence or defect effects?

Namik Kemal Gozuacik, Mustafa Cagri Bayir, M. Baris Okatan, I. Burc Misirlioglu, Sedat Alkoy, Ebru Mensur-Alkoy

Summary: This study investigates the effects of La substitution on the temperature dependent properties of PZT 70/30 ceramics and the electrocaloric effect induced by an external electric field. Experimental data and simulation results suggest that the gradual slanting of hystereses and reduction of transition temperature in La-doped samples are caused by the formation of dipolar defect complexes. The findings provide insights into the mechanism of electrocaloric effect and its potential applications in La-doped PZT 70/30 system.

Huseyin Alptekin Sari, Namik Kemal Gozuacik, Mustafa Yunus Kaya, Ebru Mensur, Sedat Alkoy

Summary: Lead zirconate stannate titanate (PZST) and lead lanthanum zirconate titanate (PLZT) ceramics were studied for their energy density and field induced strain behavior, showing changes in polar state from ferroelectric to antiferroelectric to relaxor antiferroelectric to linear dielectric with compositional modifications. Among the PZST compositions, the highest releasable energy density was obtained from the antiferroelectric composition, while the PLZT compositions with relaxor antiferroelectric character had the highest releasable energy density values with higher efficiencies.

Mustafa Yunus Kaya, Sedat Alkoy

Summary: In this study, a novel class V flextensional transducer (FT) was developed by assembling symmetrically convex ceramic and metal caps to form a seashell-like structure. The transducer displayed four distinct flextensional modes in addition to the main radial resonance mode in the frequency range of 1 to 200 kHz. Prototypical devices made from different lead zirconate titanate (PZT) compositions were compared in terms of underwater performance, and transmitting voltage responses (TVRs) above 50 kHz ranged between 120 and 135 dB (ref 1 mu Pa/V).

Boosting energy storage performance in negative temperature coefficient linear-like dielectrics via composite modulation in the superparaelectric state

Kaibiao Xi, Jiacheng Liu, Beibei Song, Huarong Cheng, Yihao Li, Xiaole Yu, Mupeng Zheng, Mankang Zhu, Yudong Hou

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Influence of raw material purity on microstructure and properties of calcia refractory

Qingzhong Song, Xiangdong Zha, Ming Gao, Yingche Ma

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Ultra-low thermal conductivity and hydrophobic properties of high entropy β-type quaternary pyrosilicate

Sehreish Abrar, Faisal Nazeer, Zhuang Ma, Ling Liu, Abdul Malik, Mustafa Kamal, Abdullah G. Al-Sehemi

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

High speed impact and solid-state deposition of alumina particles: A molecular dynamics study

S. Rahmati, R. G. A. Veiga, J. Mostaghimi, T. Coyle, A. Dolatabadi

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Long-term ablation mechanisms of the YB4-Al2O3-Si3N4 modified Cf/ HfC-SiC composites at 2600 °C

Bo-Wen Chen, Yan-Mei Kan, De-Wei Ni, Chun-Jing Liao, Hong-Da Wang, Yu-Sheng Ding, Shao-Ming Dong

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
