Abstract  The morphology, crystal defects and chemical compositions of surfacesin two kinds of SiC whiskers related to their growth mechanism have been studiedby means of electron microscopy and surface chemical analysis. Based upon the expe-rimental results, five criteria for evaluating the whisker microstructure were sugge-sted as: proportion of the perfect single crystals, morphology and dimensions, defectsand their distribution, the bulk and surface chemistries, and crystallographic charac-ters.
Key words:  SiC      whisker      microstructure      defect
