Dear Colleagues,

There is a great interest in 2D particle addition to ceramic materials due to their specific anisotropic thermal and electrical properties, self-lubricative features, unique mechanical properties, and flexibility. This Special issue is focused on such two-dimensional particles as graphene, hexagonal boron nitride, molybdenium sulfide, etc. The 2D desired phases should be distributed in a composite matrix in the field of hard nitrides, borides and carbide, MAX phases, UHTC phases, oxynitrides, and oxides as well. From the experience and literature, the low concentration of 2D particles up to 2 wt.% can lead to mechanical properties’ improvement, but higher addition will cause anisotropy of material properties. This enables, for example, gradient material production, which on the one hand is mechanically enhanced, but the gradual anisotropic layer allows dissipating heat. In such composites, material microstructure, all of the properties, possibility of their materials application will at first depend on the starting raw materials, the preparation technique, and finally, the manufacturing way (pressureless sintering, HP, SPS, PPS, HIP, HP-HT). On the other hand, material behavior during the work will also depend on the final composite shaping methods. This last stage of CMC preparation will depend on fracture toughness, thermal shock resistance, heat transfer rate, and its direction and electrical properties as well.

Summarizing, this issue will accept papers concerning:

• Raw materials and mixture preparation for densification process;
• Sintering aids for final material manufacturing;
• Various production processes of dense, uniformed, gradient, and controlled porosity materials;
• Anisotropic properties of 2D ceramic matrix composites;
• Wear and oxidation resistance of sinters;
• Thermal and electrical properties;
• Application test of 2D/ceramic composites;
• 2D/ceramic composites shaping mechanical, electrical discharge machining, subtractive laser processing, and additive manufacturing;
• High temperature ceramic filters;
• Refractory materials containing 2D particles;
• Thermal computer simulation of properties of 2D/ceramic composites.
