In situ synthesis of homogeneously dispersed SiC nanowires in reaction sintered silicon-based ceramic powders

摘要: Abstract The synthesis of homogeneously dispersed SiC nanowires in the ceramic powders arouses considerable interests due to its potential applications as reinforcements matrix composites. Herein, we reported a facile and novel approach situ synthesize reaction sintered silicon-based powders. as-synthesized exhibited single-crystalline 3C-SiC with diameters 50–200 nm lengths ranging from tens over 100 µm. Combining further experimental results thermodynamics analysis, demonstrated importance free silicon for powders, since it increased equilibrium vapor pressure SiO gaseous product system.
