Silicon nitride nanowires or nanorods have been synthesized from SiCl 4 , NaN 3 , and metallic Mg at temperatures ranging from 200° to 300°C. X‐ray powder diffraction patterns indicated that the as‐obtained products were mainly β‐Si 3 N 4 . Scanning electron microscope and high‐resolution transmission electronic microscopy showed that the samples mostly consisted of Si 3 N 4 nanowires or nanorods. As metallic iron powder was used, α‐Si 3 N 4 was mainly formed at 250°C.
