Summary: In this study, modified SiC ceramics were prepared by melt-quench method, and the effects of direct addition of raw materials and addition of amorphous sintering additives were compared. The results showed that using amorphous additives could improve the relative density and hardness of SiC ceramics.

Summary: A new experimental configuration enables pressure-assisted flash sintering of ZnO powder without pretreatment, achieving rapid and energy-concentrated heating through induction heating. The use of an insulated die allows current flow through the sample during flash sintering, leading to the rapid densification of ZnO ceramics.

Summary: Zirconia ceramics with superior mechanical properties were fabricated by adding SiC whiskers and SiC particles and using oscillatory pressure sintering technique. The ceramics exhibited improved Vickers hardness, bending strength, and fracture toughness. The enhanced toughness was attributed to synergistic toughening effects including whisker toughening, stress-induced phase transformation toughening, and particle dispersion toughening.

Summary: The limited densification of CeO2 ceramics was improved by using an anorthite-based glass, resulting in high dielectric constant and quality factor with minimum dielectric loss. The CeO2-(anorthite-based) glass ceramic showed promising results in terms of low temperature densification and microwave properties.

Summary: It has been found that there is a phenomenon of early surface densification in ceramics manufactured by stereolithography, which may have negative effects on the performance of ceramic components and needs to be controlled through optimization of the sintering protocol.

Summary: Blacklight sintering is an energy-efficient technique for rapid densification of ceramics, without the need for electrodes or complex sample holders. This study focuses on blacklight-sintered ferroelectric BaTiO3, which achieved gradient-free microstructures, enhanced electrical conductivity, and leaky ferroelectric behavior. An additional annealing step in an oxygen-rich atmosphere improved the ferroelectric properties to match conventionally sintered samples. These findings demonstrate the potential of blacklight sintering for fabricating ferroelectric ceramics if the quenching effect is considered.

Summary: In this study, a comprehensive sintering model for gas pressure liquid phase sintering (GPS-LPS) of silicon nitride was developed. The model takes into account the temperature and porosity dependence, as well as the grain growth sensitivity. It successfully reproduces the complex sintering behavior of silicon nitride.

Summary: In this study, single-phase Hf6Ta2O17 spherical powders with uniform particle sizes were successfully synthesized and pressure-less sintering produced bulk ceramics with high relative density. The thermal conductivity of Hf6Ta2O17 ceramics was investigated and found to be lower than traditional 8YSZ, making it more suitable for thermal barrier coatings. Doping other elements could potentially improve the properties of Hf6Ta2O17 ceramics.

Summary: This study successfully fabricated fully dense Si3N4/SiC nano-composites through the combination of polymer-derived ceramics method and spark plasma sintering technique. By incorporating aluminum into the precursor, the densification rate was improved, the degradation of Si3N4 phase was prevented, and excellent oxidation/corrosion resistance was achieved.

Summary: An ultra-high-pressure sintering strategy was developed to fully densify ZrC ceramic under 1.7 GPa at 1600 degrees Celsius, resulting in high density, fine grain size, excellent mechanical properties, and a large number of crystal defects. This unique microstructure led to an increased hardness of 2057.44 HV0.1.

Summary: In this work, a novel process called oscillatory pressure-assisted sinter forging (OPSF) was used to prepare high-performance ceramic composites. The SiC whisker reinforced Al2O3 composites (SiCw-Al2O3) prepared by OPSF showed higher density and improved mechanical properties compared to samples made by conventional sinter forging (SF) and hot oscillatory pressing (HOP). The enhancements in densification and performance were attributed to the simultaneous enhanced shear deformation at both macro- and micro-scales, achieved through the die-free configuration and oscillatory pressure of OPSF. The strength of grain boundary also significantly increased with temperature during OPSF.

Summary: A pressureless two-step sintering method was utilized to densify high-entropy carbide, resulting in high density and good mechanical performance. The addition of phenolic resin improved the grain and pore structure while increasing the material density. After 8 hours of soaking, the material exhibited good mechanical properties with high flexural strength and hardness.
