英文摘要	Zirconium carbide–silicon carbide (ZrC–SiC) ceramics are amongst the promising candidate materials for thermal protection structures in hypersonic re-entry space vehicles. A thermoset hybrid sol for the syntheses of monolithic ZrC–SiC composites was prepared by a simple sol–gel method. Furfuryl alcohol, polyzirconoxane and tetraethyl orthosilicate were used as raw materials. The as-synthesized sol can be cured at 85 °C for 24 h to obtain a bulk gel. The cured gel is converted into porous ZrC–SiC monolith with porosity of 44.1% after pyrolysis at 1500 °C for 1 h in vacuum. The ZrC–SiC monolith is composed of well distributed nano-sized ZrC and SiC particles. Highly porous ZrC–SiC ceramic foam with density of 0.34 g/cm3and porosity of 78.1% is prepared by replica method using the hybrid sol as precursor and melamine foam as templates. The hybrid sol and ZrC–SiC composites are characterized by FT-IR, TG–DTA, XRD, SEM, EDS and TEM. © 2018 Springer Science+Business Media, LLC, part of Springer Nature
