“…The research on ceramic/graphene composites has been mostly focused on enhancing the mechanical properties of ceramics and particularly of the fracture toughness parameter or K IC . Former studies were aimed at Al 2 O 3 and Si 3 N 4 ceramics [8][9][10][11], hence being presently the most extensively analysed systems [12][13][14][15][16][17][18], although now we can find studies on many ceramics of interest, such as SiC, ZrO 2 , ZrB 2 , B 4 C, TaC, TiC, Ti 3 Si 2 C, SiO 2 or hydroxyapatite (HA) [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. A general outcome from the available K IC data is the attested toughening effect induced by the graphene nanostructures.…”

The updated results on the relevant properties of graphene reinforced ceramic are reviewed. The representative data for a wide number of bulk composites are compared, making special emphasis on the mechanical properties (fracture toughness, strength), wear and friction characteristics, and elastic properties. The electrical functionality boosted by the contacted graphene network is critically assessed for conducting and dielectric matrices. Regarding thermal transport, the enhancement or depletion of thermal conductivity is revised considering for different matrices and for specific orientations. Furthermore, new developments on layered and coatings, as well as in cellular composites that certainly widen the scope of applications for these remarkable group of ceramic composites are looked over.

“…Liu et al reported that GNS with a large specific surface area can effectively inhibit grain growth. It is found that TiC particles practically stop growing in the presence of thin GNS [106]. The ratio of the GNS size is the most important factor hindering the grain growth.…”

AbstractNanocarbon materials (carbon nanotubes, graphene, graphene oxide, reduced graphene oxide, etc.) are considered the ideal toughening phase of ceramic matrix composites because of their unique structures and excellent properties. The strengthening and toughening effect of nanocarbon is attributed to several factors, such as their dispersibility in the matrix, interfacial bonding state with the matrix, and structural alteration. In this paper, the development state of nanocarbon-toughened ceramic matrix composites is reviewed based on the preparation methods and basic properties of nanocarbon-reinforced ceramic matrix composites. The assessment is implemented in terms of the influence of the interface bonding condition on the basic properties of ceramic matrix composites and the methods used to improve the interface bonding. Furthermore, the strengthening and toughening mechanisms of nanocarbon-toughened ceramic matrix composites are considered. Moreover, the key problems and perspectives of research work relating to nanocarbon-toughened ceramic matrix composites are highlighted.

“…The matrices investigated include borides (ZrB 2 [5]), carbides (B 4 C [6], SiC [7e10], TiC [11], TaC [12,13]), nitrides (AlN [14e17], Si 3 N 4 [18e22], TiN [23]) and oxides (MgO [24], Al 2 O 3 [25e33], SiO 2 [34], ZrO 2 [35] and hydroxyapatite [36,37]). Many processing methods involve the preparation of graphene/ceramic powders followed by a consolidation step performed by a variety of techniques including pressureless sintering, spark plasma sintering, hot pressing and hot isostatic pressing.…”

Christophe Fast and easy preparation of few-layered-graphene/magnesia powders for strong, hard and electrically conducting composites. (2018) a b s t r a c tComposite powders were prepared by the chemical vapor deposition (CH 4 /Ar atmosphere) of carbon in the form of 2e8 layers few-layered-graphene (FLG) covering the MgO powder grains, without any mixing step. The composites were consolidated to nearly full (99%) density by spark plasma sintering with no or little damage to the FLG. The FLG is located along the MgO grain boundaries, as opposed to be dispersed as discrete particles or flakes. This causes a dramatic hindrance of the MgO grain growth, the average grain size being considerably lower for the sample with 2.08 vol% carbon (200 nm) than for pure MgO (3.7 mm). The samples are investigated by Raman spectroscopy, scanning and transmission electron microscopy. The composites are electrically conducting with a percolation threshold below 0.56 vol%. Compared to pure MgO, the composites are simultaneously stronger (345 vs 200 MPa) and harder (9.8 vs 3.8 GPa). This could arise from reinforcement mechanisms such as crack-deflection and crack-bridging by FLG, but also from MgO grain refinement.
