The invention relates to a ceramic-based composite material with an electromagnetic impedance gradient body, which is characterized in that a C-SiC-based composite material is prepared from a porous carbon-based composite material, and then a Si < 3 > N < 4 > matrix is prepared from the C-SiC-based composite material.
本发明涉及一种具有电磁阻抗渐变集体的陶瓷基复合材料，由多孔碳基复合材料制备成C‑SiC基复合材料，再由C‑SiC基复合材料制备成Si 3N 4基体。
