✦ Synopsis

ZrB2–20vol%SiC ceramics without and with additive of 2wt% carbon nanotubes (CNTs) were fabricated by hot-pressing at 1900°C for 1h under 30MPa using ZrB2, SiC and CNTs as starting materials. The fracture toughness increased about 15%, but hardness, flexural strength as well as thermal conductivity did not vary significantly from the addition of CNTs.

In the present work, the thermal shock resistance of the ZrB 2 -SiC-ZrC ceramic was estimated by the water quenching method and the flexural strength of the quenched specimen was measured. The measured critical temperature difference of the ZrB 2 -SiC-ZrC ceramic was significantly greater than that

ZrB 2 -based nanocomposite ceramics, which were enforced by nanosized SiC particles with the sizes of 100 and 20 nm, respectively, were prepared by spark plasma sintering. Both mass fraction and size of the nanosized SiC particle have a great effect on the relative density and fracture toughness of
