▎ 摘　　要

NOVELTY - Preparing graphene composite nano-hexagonal barium ferrite wave-absorbing material comprises (i) preparing nano M-type barium ferrite powder with hexagonal molecular structure by sol-gel self-propagating combustion method; (ii) mixing the nano M-type barium ferrite powder with hexagonal molecular structure with glucose particles, adding water, grinding, ultrasonic processing, and drying to obtain mixed material; (iii) placing the mixed material in the crucible filled with microwave vacuum tube furnace, vacuuming, introducing nitrogen, and microwave heating; and (iv) taking out the crucible, and cooling. USE - Preparation method of graphene composite nano hexagonal barium ferrite wave-absorbing material used in civil field and military field. Uses include but are not limited to communication, military, civil radar and other application fields. ADVANTAGE - The method has simple process steps, low device requirement, controllable process, safety ferrite and graphene composite effect.
