Abstract

Pyrolytic carbon-Si₃N₄ ceramics (PyC-Si₃N₄) with gradient PyC distribution (Gradient-PyC-Si₃N₄) is fabricated by directional oxidation. After directional oxidation for 1.0h, the electromagnetic absorptivity of Gradient-PyC-Si₃N₄ increases significantly from 0.8 to 50.1% with the obvious reduction of electromagnetic reflectivity from 99.2 to 43.8%. The Gradient-PyC-Si₃N₄ is a good electromagnetic absorbing material meeting the requirement of self-concealing technology.
