Abstract

The worm like silicon carbide nanofibers were synthesized by simple carbothermal reduction technology. Low cost water glass and phenolic resin were used as raw materials. The synthesized samples were characterized by XRD, FESEM, TEM, N2 adsorption and fluorescence spectrophotometer. The results indicate that the products are worm-like β-SiC nanofibers with diameters of 20 110 nm nm. The maximum surface area of synthesized SiC is up to 51.6 m2/g. Strong photoluminescence peaks located around 450 nm and 468 nm are observed at room temperature, which can be ascribed to quantum size effects, microstructures and defects within the SiC materials..
