摘要：

beta -Si3N4 nano-fibers with diameters of about 60-400 nm were fabricated through a combustion synthetic route. These fibers have straight, twisted, and curved morphologies. X-Ray powder diffraction pattern and the selected area electron diffraction spots confirmed the beta -Si3N4 phase for these fibers. A droplet at the tip of a fiber was found and aluminium impurity was detected on the droplet, which demonstrates the Vapor-Liquid-Solid (VLS) mechanism. (C) 2001 Elsevier Science BN.
