Abstract: | The microstructure of fiber-like SiC/Si3N4 composite particulate was investigated using high-resolution transmission electron microscopy techniques. The SiC/Si3N4 composite particulate consisted of a-SiC core and a -Si3N4 outer shell. Two kinds of composite particulate were distinguished when the observed orientation of the SiC core was <110>. In one type of the SiC/Si3N4 composite particulate, a crystal relationship of (111)-SiC | (102) -Si3N4 and (111)-SiC (114) -Si3N4 was identified; in the other type of the SiC/Si3N4 composite particulate, a crystal relationship of (111)-SiC (001) -Si3N4, and (111)-SiC (101) -Si3N4 was observed. |
