Special Issue Information

Dear Colleagues,

There is growing demand for high-performance ceramic materials across advanced engineering applications, including cutting tools, mining components, aerospace systems and biomedical devices. Modern processing techniques such as electroconsolidation, spark plasma sintering and nanoscale powder engineering offer unique opportunities to tailor the microstructure, densification behavior and mechanical properties of ceramic-based composites. The optimization of these materials requires a deep understanding of phase transformations, grain-boundary phenomena, fracture mechanisms and functional performance under extreme operating conditions.

This Special Issue aims to gather papers demonstrating recent advances in the design, processing and characterization of structural ceramics and ceramic composites. We welcome original research papers and comprehensive reviews that explore innovative synthesis routes; modeling of sintering and microstructure evolution; mechanical and tribological testing; and the development of nanostructured and hybrid ceramic systems with enhanced strength, toughness and thermal stability.

Zirconia-based ceramics find wide application in engineering due to their very high hardness, resistance to elevated temperatures, and high fracture toughness. Among stabilizers of the advantageous tetragonal zirconia phase, yttria allows for better grain size refinement than ceria does; thus, Y2O3 is the most widely used. In the present study, comparative analysis was performed for yttria-stabilized zirconia (YSZ) and ceria-stabilized zirconia (CSZ) in terms of sinterability, densification, and mechanical properties, including hardness and resistance to plastic deformation. The results proved that CSZ sintered in similar conditions as YSZ exhibits similar properties, including an elastic modulus of 200–220 GPa and H/E of 0.070–0.076. In particular, the hardness of the ZrO2–5 wt% CeO2 ceramic appeared to be 14.6 ± 0.5 GPa, close to that of ZrO2–3 wt% Y2O3, which was 14.20 ± 0.74 GPa. However, SiC addition to ZrO2–5 wt% CeO2 composites increased hardness substantially up to 16.8 ± 0.8 GPa. Moreover, the fracture toughness of CSZ was 2.5 times higher than that of YSZ sintered under identical conditions. Thus, CeO2 can be a good, cheaper alternative to the traditionally used Y2O3 stabilizer for submicron-grained tetragonal zirconia ceramics. Full article
