| Abstract | The synthesis of nano-sized SiC through ball milling (BM) of elemental Si and graphite mixed powders at room temperature has been reported, and detailed reaction process has been characterized by high-resolution electron microscopy (HREM). High-resolution electron microscopy (HREM) observations presented herein suggest that amorphous graphite (a-graphite), amorphous silicon (a-Si) and nano-sized crystalline Si (c-Si) with many defects are produced during BM, which is prerequisite to the reaction. In some areas, SIC is synthesized through a diffusion of C atoms into the a-Si/and c-Si. In the former, a-Si(C) forms, and then mechanically-driven crystallization of the a-Si(C) occurs to form SIG. In the latter, C atoms directly replace Si atoms to form SIC with an orientation relationship of (111)(SiC)//(111)(Si). In other areas, localized self-sustained reaction occurs to form slightly larger SIC grains. (C) 2001 Elsevier Science B.V. All rights reserved. |
