SiC fibers were synthesized on the surface of reaction sintered SiC substrate by Si vapor deposition without catalyst at 1700 degrees C for 4 h in the nitrogen atmosphere. SiC fibers were characterized by scanning electron microscopy, transmission electron microscopy and X-ray diffraction. The results indicate that the fibers have beta-SiC structure and their diameters are several-hundred nanometers. The length of the SiC fibers is similar to 1.5-3.0 mm and their growth direction is [111]. Investigation of growth mechanism indicates that the SiC fibers grow via the vapor-solid (VS) growth process. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights
