ZrB 2–SiC composites were fabricated by hot pressing with various nano-carbons (nano-graphite, nano-graphene, nano-carbon black and carbon nanotube) in order to scrutinize the densification and mechanical properties. Microstructure analyses show that the grain size of the sintered samples highly depends on the nano-carbon morphology. Hot pressed samples using nano-carbon as the reinforcement phase, except carbon nanotube, exhibit improved density and mechanical properties.
