Microstructure Observation and Analysis of Powders, Green Bodies Used for Sintering SiC Ceramics by SEM

Abstract:

The present work observed and analyzed the microstructures of various starting powders including SiC, AlN-R (Y / La) ₂O₃ as additives for LPSing (Liquid Phase Sintering), B/C additives for SSSing (Solid State Sintering), as well as the spray granulated powders as comparison, by using scanning electron microscopy SEM. The microstructure of molded green bodies was also posted. Present paper opens out the characters of the various perfect and defect of microstructures of these samples. Their effect on the processing and properties of SiC ceramics was analyzed and discussed.
