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 degrees C for 24h to obtain a bulk gel. The cured gel is converted into porous ZrC-SiC monolith with porosity of 44.1% after pyrolysis at 1500 degrees C for 1h 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 0.34g/cm(3) and 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.
