摘要

Iron nitride @flaky carbonyl iron particles possessing improved antioxidation and microwave absorption properties were successfully prepared by surface nitridation method with urea as nitrogen source. The XRD result indicates generation of Fe₃N and Fe₄N on the surface of FCI, which is marked as Fe_3-4N@FCI. The SEM image shows the core-shell structure of the Fe_3-4N@FCI. The TG curves exhibit the obvious oxidation temperature rising up to 400 °C after surface nitridation. Moreover, the Fe_3-4N@FCI/silicon resin composite has almost invariable electromagnetic parameters and reflection loss (RL) values after heat treatment at 250 °C for 30 h.
