Summary: Nacre-like alumina ceramics with zirconia particles uniformly distributed between the layers are successfully fabricated using freeze casting and hot pressing. The addition of zirconia greatly improves the flexural strength and fracture toughness of the material. Microstructure observation and fracture behavior analysis reveal that the enhanced mechanical properties are attributed to the bioinspired nacre-like structure and stress-induced transformation toughening.

Summary: The crystallization of glass has a significant impact on the microstructure and ion-exchange properties of transparent glass-ceramics. Through sequential crystallization of ZnAl2O4 and beta-quartz solid solution nanocrystals, the glass-ceramics show smaller grain size, more uniform structure, and higher transparency. The ion-exchange depth increases significantly after crystallization, as the content of zinc and five coordinated aluminum in the residual glass matrix decreases.

Summary: This study evaluated the composition, microstructure, optical properties, and mechanical properties of eight commercially available dental zirconias. The results showed that the chemical composition and grain size of the zirconia had an impact on its properties. Future research should focus on improving the optical properties and mechanical reliability of zirconia ceramics.

Summary: In this paper, alumina matrix composites were fabricated by hot-pressing with the incorporation of additives including zirconia, alumina platelets, and MXene. The influence of these additives on the microstructure and mechanical properties of the composites was investigated. The results showed that the bending strength and fracture toughness of alumina were greatly improved by the introduced additives. Zirconia contributed to the improvement of mechanical properties through phase-transformation strengthening and toughening mechanism, while alumina platelets enhanced fracture toughness by self-toughening of elongated grains. In addition, the combined effect of alumina platelets and MXene significantly increased the fracture toughness of the composite.

Summary: Constructing a novel graded glass/zirconia ceramic by utilizing the interdiffusion between dense zirconia and a novel lithium disilicate glass in the SiO2-Li2O-Al2O3 system is a promising solution to reduce cracking and delamination of bilayered zirconia prosthesis. The constructed graded glass/zirconia structure exhibited obvious gradient characteristics in microstructure, glass content, and mechanical properties. The study elucidated the mechanism of the evolution of the graded structure and the change of strength, providing a promising strategy to improve the interface stability of bilayered zirconia restoration.

Summary: Erbium oxide transparent ceramics were successfully fabricated with different contents of zirconia additive, and the effects of zirconia concentration on the microstructure, optical, mechanical, and thermal properties were investigated. Increasing the zirconia concentration resulted in smaller grain size and increased hardness and fracture toughness, but slightly decreased thermal diffusion coefficient and thermal conductivity. The doped ceramics showed absorption peaks and achieved high in-line transmittance in the visible range.

Summary: This paper focuses on the preparation of a smart wearable purple ceramic that meets the color requirements of purple smart wear in the market. The addition of 3 mol% yttria-stabilized zirconia (3YSZ) to zirconate neodymium improves its mechanical properties, particularly its fracture toughness. The mechanical properties of the ceramic samples improve with the increase in 3YSZ content and the decrease in temperature. The prepared ceramic samples with 80% 3YSZ content sintered at 1400 degrees C exhibit significantly improved fracture toughness and Vickers hardness compared to undoped neodymium zirconate, making them suitable for engineering toughening of zirconate ceramics.

Summary: Lithium-aluminum-silicate glass-ceramics (LAS) are important due to their excellent mechanical and functional properties. In this study, solid-state field-assisted ion exchange was carried out in LAS glass-ceramics containing 8-quartz and 8-spodumene solid solutions, resulting in rapid and deep silver penetration. The structural modifications induced by ion exchange led to improved crack resistance and antimicrobial activity of the materials.

Summary: By modifying Pb(ZrxTi1-x)O3 (PZT) ceramics with yttria-stabilized zirconia (YSZ) using conventional solid-state sintering technology, the mechanical strength and fracture toughness of PZT piezoelectric ceramics can be significantly improved while suppressing the reduction tendency of major piezoelectric properties. The piezoelectric coefficient d33 of the YSZ-modified PZT ceramic remains nearly unchanged and the electromechanical coupling coefficient kp remains high.
