摘要

Si ₃N ₄-coated porous pyrolytic carbon-Si ₃N ₄ ceramics (PyC-Si ₃N ₄/Si ₃N ₄) were fabricated by chemical vapour infiltration of PyC into porous Si ₃N ₄ ceramic and then chemical vapour deposition of Si ₃N ₄ coating on the surface of the obtained PyC-Si ₃N ₄. The PyC-Si ₃N ₄/Si ₃N ₄ with 3.1vol.% PyC content possesses electromagnetic reflection loss as low as -11.5dB. Due to the excellent sealing effect of dense Si ₃N ₄ coating, the PyC-Si ₃N ₄/Si ₃N ₄ possesses good oxidation resistance, which makes PyC-Si ₃N ₄/Si ₃N ₄ a good electromagnetic absorbing material that can be used at temperature as high as 1100°C.
