Growth of SiC nanowires within stacked SiC fiber fabrics by a noncatalytic chemical vapor infiltration technique

Chemistry of one dimensional silicon carbide materials: Principle, production, application and future prospects

“…The synthesis methods that have been used to synthesize SiC nanomaterials can be broadly classified into following categories: (a) carbothermal reduction of silica [107][108]; (b) decomposition of organic silicon compounds /polymers [109]; (c) reaction between silicon halides and CCl 4 ; [110] (d) reacting carbon nanoclusters with SiO at elevated temperature [111][112]; (e) metal catalyzed reduction of silicon/silica powder [113][114]; (f) high temperature catalytic reaction of SiC powder [115]; (g) chemical vapor deposition (CVD) with the aid of catalysts through the vapor-liquid-solid (VLS) mechanism [116][117] and (h) CVD process, hydrogen reduction of methyltrichlorosilane (CH 3 SiCl 3 ) [118][119].…”

“…In addition the feed molecules also need to be supplied at a well controlled rate in order to obtain crystals having a homogeneous composition and uniform morphology. The carbothermal reduction of silica [25][26][27] and hydrogen reduction of methyltrichlorosilane [28][29][30][31] are the two most widely used methods. The bulk production of 1D SiC nanostructures is a challenging issue which is currently being undertaken by different research groups [32][33][34][35][36][37][38].…”

Synthesis of centimeter-scale ultra-long SiC nanowires by simple catalyst-free chemical vapor deposition

“…Many groups in the worldwide have carried out their work to synthesize the SiC nanowires and characterize their various excellent properties. Up to now, many fabricated methods were demonstrated, including carbon nanotubes confined reaction [6][7][8], chemical vapor deposition/infiltration (CVD/CVI) [9][10][11][12], carbothermal reduction [13][14][15], thermal evaporation [16,17], polymer pyrolysis [18], etc. However, most of the SiC nanowires synthesized by these methods have their length only up to tens of micrometers.…”

Effect of SiC Nanorods on Mechanical and Thermal Properties of SiC Composites Fabricated by Chemical Vapor Infiltration

“…Stacking fault formation of nanowires or whiskers by CVD has been reported in previous studies and has also been reported in whisker growth by solid-gas reactions such as carbothermal reactions. 19,[22][23][24] As can be seen in the microstructure of Fig. 2, the SiC nanorods grow evenly in the radial direction on the surface of the SiC fiber.…”
