Summary: Five mullite foamed ceramics were prepared with different Si powder contents to investigate the effect of in-situ SiC whisker generation on the properties of the ceramics. The rise in Si powder content led to decreased porosity, increased thermal conductivity, and initially increased and then decreased compressive strength. The alkali corrosion resistance was improved by reducing alkali vapor diffusion rate and improving ceramic matrix stability. Considering mechanical properties, thermal insulation, and alkali attack resistance, the optimal Si powder content was found to be 10 wt%.

Summary: In solid-state Li-metal batteries, both Li-ion diffusion and electron transport play crucial roles in the corrosion of the solid-state electrolyte LAGP. Li-ion injection at specific sites leads to the fast degradation of LAGP, while ambipolar diffusion at the interface promotes the growth of the mixed conducting interphase (MCI). Separating the diffusion of electrons and ions slows down the growth rate of MCI. Therefore, both ion and electron transport are equally important in the electrochemical corrosion of LAGP.

Summary: This study investigated the feasibility of recycling ceramic polishing waste (CPW) in porcelain tile production and its impact on the phase composition, microstructure, and properties of the ceramic body. It was found that high CPW content can promote liquid phase formation at low temperatures, but may cause foaming or expansion at high temperatures, reducing mechanical properties. Successful preparation of porcelain tiles with CPW content of <= 30 wt% at firing temperatures of 1125-1200 degrees C was achieved, providing valuable insights for CPW utilization.

Summary: In this study, a new type of ZTA bioceramic with high fracture toughness, superior wear resistance, and low-temperature degradation (LTD) resistance was synthesized by introducing nano-crystalline PrAlO3 and co-stabilised tetragonal phase zirconia (t-ZrO2) into the ZTA matrix. Praseodymium hexaaluminate (PHA) plate-like crystals formed by solid-state sintering played a key role in toughening, while Y-Pr co-doped t-ZrO2 slowed down the LTD of ZTA bioceramics. The combination strategies positively influenced the mechanical properties of the ceramics after hydrothermal ageing. This study provides a novel direction for ensuring the long-term safety of bioceramics.
