Synthesis of a new low-toxic monomer obtained from glucose is reported and its application in gelcasting process is presented. The new monomer named 3-O-acrylic-D-glucose is an interesting alternative for the commercially available acrylic monomers. The presence of many hydroxyl groups in the monomer molecule allows to create hydrogen bonds in the polymer network. The resulting network does not need any external cross-linking agent to obtain a rigid ceramic part. The present paper describes the properties of ceramic slurries, green and sintered elements obtained from two alumina powders of different grain size (0.21 mu m and 0.70 mu m)with the use of the new monomer 3-O-acrylic-D-glucose and commercially available 2-hydroxyethyl acrylate.

Microstructure evolution and reaction mechanism of Pb(Zr1/2Ti1/2)O3-Pb (Zn1/3Nb2/3)O3-Pb(Ni1/3Nb2/3)O3 piezoelectric ceramics with plate-like PbTiO3 template

Leilei Li, Junting Liu, Shuyao Cao, Jie Xu, Changying Wu, Emilia Pawlikowska, Mikolaj Szafran, Feng Gao

Summary: This study investigated the microstructure evolution and reaction mechanism between the matrix and plate-like PT template in PZNNT ceramics. It was found that the plate-like PT template decomposed at high temperatures and reacted with the PZNNT matrix, but did not contribute to grain growth orientation. The thermal stability of the plate-like template was identified as a key factor in fabricating textured piezoelectric ceramics.

Elastic isotropy originating from heterogeneous interlayer elastic deformation in a Ti3SiC2 MAX phase with a nanolayered crystal structure

Ruxia Liu, Masakazu Tane, Hajime Kimizuka, Yuji Shirakami, Ken-ichi Ikeda, Seiji Miura, Koji Morita, Tohru S. Suzuki, Yoshio Sakka, Lianmeng Zhang, Tohru Sekino

Summary: In this study, the elastic properties of single-crystalline Ti3SiC2 MAX phase were investigated using polycrystalline samples with crystallographic texture. The results showed that despite its highly anisotropic layered structure, the single-crystalline Young's modulus was almost isotropic, with differences in shear modulus depending on crystallographic directions. First-principles calculations suggested that heterogeneous interlayer elastic deformation due to Ti-Si bonding stabilization is the origin of the elastic isotropy in Ti3SiC2 MAX phase.

Improving functional properties of protective coatings obtained by electrophoretic deposition on steel interconnects for solid oxide cells by tuning particle size distribution

Leszek Ajdys, Agnieszka Zurawska, Magdalena Kosiorek, Yevgeniy Naumovich, Magdalena Zybert, Paulina Wiecinska, Ming Chen

Summary: This paper analyzes the effect of particle size distribution on the quality of electrophoretic deposition coating. The results show that increasing the fine powder fraction can improve the density of the coating and slow down the growth rate of oxides, leading to a decrease in surface resistance. Samples prepared with admixed powder exhibit the lowest resistivity. Post-test analysis indicates no diffusion of chromium through the fabricated layers, indicating the reliability of the protective barrier.

Summary: This paper describes the chemical modification of graphene oxide (GO) surface with glucosamine, and the efficiency of the reaction was confirmed. The functionalization of GO significantly reduces the agglomeration of graphene oxide platelets. The interactions between GO and two types of ceramic nanoparticles were also investigated, and the addition of GO and f-GO increased the viscosity of the ceramic suspensions.

Summary: In the fabrication of metal-reinforced ceramics, using coordination complexes instead of metallic powders can result in nanocomposites with improved fracture toughness. In ZrO2/Mo composites fabricated with molybdenum coordination complexes, the addition of a small concentration of the metallic phase leads to the formation of fine metallic particles, which inhibit crack propagation through three mechanisms.

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.
