“…In addition to the above-mentioned methods, matrix composites can also be used to improve the i properties of Si 3 N 4 . Components such as TiN, SiC whiskers, ZrO 2 nanofibers and graphene can be used as reinforcing phases [ 11 , 12 , 13 , 14 , 15 , 16 ]. Very interesting research results have been obtained in the case of composites reinforced with graphene.…”

This paper discusses the influence of Ti3C2 (MXene) addition on silicon nitride and its impact on the microstructure and mechanical properties of the latter. Composites were prepared through powder processing and sintered using the spark plasma sintering (SPS) technic. Relative density, hardness and fracture toughness, were analyzed. The highest fracture toughness at 5.3 MPa·m1/2 and the highest hardness at HV5 2217 were achieved for 0.7 and 2 wt.% Ti3C2, respectively. Moreover, the formation of the Si2N2O phase was observed as a result of both the MXene addition and the preservation of the α-Si3N4→β-Si3N4 phase transformation during the sintering process.

Silicon nitride nanowires have been prepared by carbothermal reduction followed by nitridation of silica gel by in situ generation of ultrafine carbon as well as nitrogen over a temperature range of 1200-1350uC. Before the heat treatment dry silica gel is subjected to repeated evacuation followed by purging with ammonia. Ammonia is adsorbed on the silica gel surface and forms a ;Si-NH 2 bond which acts as a source of in situ generation of nitrogen and decomposition of dextrose provides ultrafine carbon respectively at the reaction temperature. During a high temperature heat treatment ultrafine carbon reduces the partial pressure of oxygen required for the generation and stabilisation of silicon nitride nanowires. The nanowires synthesised by this process are of 20-40 nm diameter and y1 mm length. The nanowires are characterised by XRD and filed emission SEM and EDAX.
