Abstract:

Article Preview

Reaction-formed silicon carbide (RF-SiC) ceramics can be prepared by melt Si-infiltration of the carbon preform which fabricated by casting of carbon powder of hemp straw. In order to make clear the pore structure of the carbon powder of hemp straw which affect the mechanical property of RF-SiC ceramics, the morphology and inherent pore structure of carbon powder of hemp straw were characterized with powder X-ray diffraction, laser diffraction size analysis, scanning electron microscopy, transmission electron microscopy, mercury porosimetry and nitrogen adsorption. The results indicated that some parts of interconnected macroporous and mesoporous structures of hemp straw still remained after carbonization and the RF-SiC ceramics with outstanding performance can be fabricated with this carbon powder by melt Si-infiltration of the porous preform
