To meet the emerging demands for thermal protection materials is a critical challenge. Researchers in China developed a novel porous high-entropy carbide (PHEC) ceramic fabricated by a self-foaming method using commercially available metal chloride and furfuryl alcohol as the precursor. The PHEC ceramic was constructed by microspheres with a size of 2 µm, high porosity and an interconnected frame. The microspheres consisted of high-entropy carbide grains resulting in abundant interface and nanosized pores in the PHEC ceramic. It has outstanding compressive strength and exceptionally low thermal conductivity at room temperature. According to the researchers their work provides a cost-effective facility strategy to produce a promising thermal insulation material for ultrahigh temperature application… read more.
