“…A 2 wt% addition of the MXene phase is enough for the phase transformation to be blocked, with a simultaneous creation of Si 2 N 2 O phases. Ding et al [45], in turn, proposed a method of obtaining MXene derived TiC/SiBCN ceramic materials for electromagnetic shielding. While heating the mixture of carbon-rich hyperbranched polyborosilazane precursor (hb-PBSZ) and Ti 3 C 2 T x MXene, the forming titanium oxides react with carbon and produce titanium carbide.…”

This article describes the manufacturing of silicon carbide composites with the addition of quasi-two-dimensional titanium carbide Ti3C2, known as MXene. The composites were obtained by the powder metallurgy technique, consolidated with the use of the Spark Plasma Sintering method at 1900 °C and dwelled for 30 min. The influence of the Ti3C2 MXene addition on the microstructure and mechanical properties of the composites was investigated. The structure of the MXene phase after the sintering process was also analyzed. The results showed a significant increase (almost 50%) of fracture toughness for composites with the addition of 0.2 wt% Ti3C2 MXene. In turn, the highest hardness, 23.2 GPa, was noted for the composite with the addition of the 1.5 wt% Ti3C2 MXene phase. This was an increase of over 10% in comparison to the reference sample. The analysis of chemical composition and observations using a transmission electron microscope showed that the Ti3C2 MXene phase oxidizes during sintering, resulting in the formation of crystalline, highly defected, disordered graphite structures. The presence of these structures in the microstructure, similarly to graphene, significantly affects the hardness and fracture toughness of silicon carbide.

“…However, the presence of MXene in the final microstructure has not been confirmed. In the research [32], the oxidation of MXene phases was used to obtain TiC/SiBCN composites. During heating, the titanium oxide, formed as a result of decomposition of Ti 3 C 2 T x , reacted with carbon to form in situ particles of TiC.…”

This article presents new findings related to the problem of the introduction of MXene phases into the silicon carbide matrix. The addition of MXene phases, as shown by the latest research, can significantly improve the mechanical properties of silicon carbide, including fracture toughness. Low fracture toughness is one of the main disadvantages that significantly limit its use. As a part of the experiment, two series of composites were produced with the addition of 2D-Ti3C2Tx MXene and 2D-Ti3C2Tx surface-modified MXene with the use of the sol-gel method with a mixture of Y2O3/Al2O3 oxides. The composites were obtained with the powder metallurgy technique and sintered with the Spark Plasma Sintering method at 1900 °C. The effect adding MXene phases had on the mechanical properties and microstructure of the produced sinters was investigated. Moreover, the influence of the performed surface modification on changes in the properties of the produced composites was determined. The analysis of the obtained results showed that during sintering, the MXene phases oxidize with the formation of carbon flakes playing the role of reinforcement. The influence of the Y2O3/Al2O3 layer on the structure of carbon flakes and the higher quality of the interface was also demonstrated. This was reflected in the higher mechanical properties of composites with the addition of modified Ti3C2Tx. Composites with 1 wt.% addition of Ti3C2Tx M are characterized with a fracture toughness of 5 MPa × m0.5, which is over 50% higher than in the case of the reference sample and over 15% higher than for the composite with 2.5 wt.% addition of Ti3C2Tx, which showed the highest fracture toughness in this series.

Mo 3 C 2 @N-doped carbon microspheres (Mo 3 C 2 @ NC) have been discovered to be a family of superior microwave absorbing materials. Herein, Mo 3 C 2 @NC was synthesized through a simple high-temperature carbonization process by evaporating a graphite anode and Mo wire in Ar and N 2 atmospheres with an Ndoping content of 6.4 at. %. Attributing to the self-assembly mechanism, the number of Mo wires inserted into the graphite anode determined the morphologies of Mo 3 C 2 @NC, which were the unique lemon-like (1-and 2-Mo 3 C 2 @NC) and fig-like (3-, 4-, and 5-Mo 3 C 2 @NC) microstructures. 1-and 2-Mo 3 C 2 @NC exhibited powerful reflection losses (RLs) of −45.60, −45.59, and −47.11 dB at the S, C and X bands, respectively, which corresponded to thinner thicknesses. 3-, 4-, and 5-Mo 3 C 2 @NC showed outstanding absorption performance at the C, X, and Ku bands, respectively, with each value of a minimum RL less than −43.00 dB. In particular, the strongest RL (−43.56 dB) for 5-Mo 3 C 2 @NC corresponded to an ultrathin thickness of 1.3 mm. In addition, the maximum effective absorption bandwidth was 6.3 GHz for 4-Mo 3 C 2 @NC. After analysis, all Mo 3 C 2 @NC samples showed well-matched impedance due to the enhanced dielectric loss caused by the unique carbon structure and moderate magnetic loss derived from the weak magnetic property of Mo 3 C 2 . More importantly, the unique lemon-like and fig-like microstructures created sufficient interfaces and differentiated multiple reflection paths, which greatly contributed to the strong microwave absorptions at full wavebands. In full consideration of the simple preparation method and tunable absorption properties, Mo 3 C 2 @NC composites can be regarded as excellent electromagnetic wave absorption materials.
