摘要

The mechanical and electromagnetic (EM) properties of Si₃N ₄ ceramic were improved by infiltrating SiC into porous Si ₃N₄ ceramic by chemical vapor infiltration (CVI). After CVI of SiC, the Si₃N₄-SiC ceramic possesses improved mechanical properties, high permittivity and dielectric loss, and excellent EM shielding effectiveness and EM absorbing properties compared to Si ₃N₄ ceramic. The lowest EM reflection loss appears when the thickness of the Si₃N₄-SiC ceramic equals a quarter-wavelength, and the reflection loss remains unchanged for larger thicknesses.
