ABSTRACT
To ascertain the impact of graphite flake diameter on the microstructure and mechani-
cal properties as well as resistance to thermal shock, graphite flakes of various diameters
have been added to zirconium dibromide (ZrB2) 20 vol.% nano-silicon carbide (SiC) 20 vol.%
graphite (ZSnpG) ceramics. The objective of this study is to investigate the effect of graphite
flake diameter on silicon carbide nanomaterials. The study aims to identify a strategy for
achieving high comprehensive performance of ZrB2-based ceramics incorporating graphite
for future research on ultra-high temperature ceramics (UHTCs). The dispersion of mea-
surements has been conducted by combining a solid powder with ethanol at various mass
fractions. The results demonstrated that, while no changing fracture toughness considerably,
the relative density and flexural strength of ZSnpG ceramics initially increased and then de-
clined with graphite diameter increasing. The micro-crack length reduction due to residual
thermal stress, appearance of silicon carbide nanoparticles within granulation, and manage-
ment of graphite distribution all contributed significantly to the improvement of flexural
strength ZSnpG ceramics. According to the computed thermal shock parameters, ZSnpG
ceramics fracture propagation was constrained by graphite with a larger starting diameter
and prevented with a finer starting diameter.
