Summary: This research focuses on the production of silicon carbide foam using slurry and the effect of coating layers and sintering temperature on the microstructure, strength, and thermal shock resistance of the foam. The results showed that multi-layer coating improved the mechanical strength and thermal shock resistivity of the foam, and the optimum strength was obtained in a four-layer coated sample sintered at 1000 degrees C. The study also found that burning off bentonite and silica sol at 1100 degrees C reduced strength and thermal shock resistance.

Summary: This study reports a simple and commercially viable strategy to produce thermoplastic composite foams for thermal insulation applications. By incorporating porous-shell hollow-interior glass spheres (PHGS) as a filler and utilizing expandable thermoplastic microspheres (EMS) as a physical blowing agent, the resulting foams demonstrate both low thermal conductivity and lightweight mechanical reinforcement. The optimized foam formulation achieved a lightweight and robust insulation material with thermal resistivity greater than 27.7 m center dot K/W (R/in. > 4), comparable to some commercial thermoplastic insulating materials.

Summary: The production of durable, non-combustible, heat-insulating materials is very important. Foam glass is one of the most promising materials. This study investigates the role of carbon phase formed during the thermal destruction of organic foaming agent in the foaming process of glass. The results show that the carbon phase is represented by nanometer particles of amorphous sp(2)-carbon, and the foaming mechanism involves nanoparticles settling and immersing into the glass surface, reacting with sulfate ions from the glass to release gases.

Summary: The electric field did not affect the relative density of flash sintered 8YSZ. However, electric fields stronger than 300 V cm-1 transformed the cubic structure to tetragonal. The applied electric field did not influence the average grain size of samples, but caused changes in the grain boundary characteristics in flash sintered samples. The oxygen vacancy concentration in the grain boundary of flash sintered samples was significantly higher than conventionally sintered ones, leading to improved conductivity.

Summary: Flash sintering is a beneficial technique for preparing ceramic materials with high sintering temperature, but requires further research. Prolonged flash sintering of 8YSZ samples showed that densification occurred at the flash point, and increasing the holding time did not affect density. X-ray diffraction and Raman spectroscopy demonstrated a phase transformation at 30 minutes of holding time. The total ionic conductivities increased from 0.061 to 0.82 S/cm from 1 to 30 minutes of holding time, then decreased to 0.063 S/cm at 60 minutes. Oxygen vacancies were found to be generated at both grain and grain boundaries during flash sintering.

Summary: The thermal stability and surface area of γ-alumina can be improved by incorporating various transition and rare earth metals. In this study, Zr and Zr-La doped alumina granules were synthesized, and the results showed enhanced thermal stability and surface area. The co-doping process with Zr and La dopants occupied vacancies in the alumina structure, preserving the mesoporous structure and suppressing α-alumina formation up to 1200 °C. These Zr-Al co-doped alumina granules can be suitable for industrial catalyst supports.
