Synthesis of Nanotube Array Composed of an Amorphous Matrix Embedded with NaCl‐Type SiC Crystallites by Chemical Vapor Infiltration Techniques

Highly dense oriented arrays of nanotubes were synthesized via a chemical vapor infiltration process using anodic alumina membrane as a template. The nanotubes have a unique granular structure, which is composed of SiC nanocrystals embedded in an amorphous matrix. X‐ray diffraction and high‐resolution transmission electron microscopy examinations both indicate an NaCl‐type crystalline structure of the SiC nanocrystals in the nanotubes. The process described here can be extended to the preparation of other nanomaterials that are suitable to be obtained via a vapor–solid approach.
