| Features of synthesis of particles, wires, tubes, films and bulk materials based on silicon carbide in nanocrystalline/amorphous condition are considered. The main attention is taken to the preparation of nanotubes/nanowires, films and nanosized SiC inclusions in matrixes. Their structure, physical, chemical and mechanical properties are discussed in connection with the influence of size effects and other features in detail. Such new results, as the hardness essential increase, display of the nanowire high plasticity, substantial in crease of photoluminescence spectra intensity, biocompatibility, good resistance to amorphization under irradiation and so on, are described. Applications in electronics, optics, nanotechnics and medicine are pointed. Some unresolved problems are underlined. |
