A series of Ni3S2/C composites have been synthesized via molten salt synthesis. The microstructures, dielectric properties, magnetic properties and microwave absorption behavior of these Ni3S2/C composites were systematically investigated. The results indicate that new bonds and interfaces between C and Ni3S2 were formed via molten salt synthesis. The prepared Ni3S2/C exhibits excellent microwave absorption performance, where its microwave absorption strength reaches ?69.82 dB at 11.24 GHz. This microwave absorption performance is greatly superior to that of most current reports. A model related to conductive loss, magnetic loss and polarization relaxation loss was built to explain the multiple loss mechanism of the Ni3S2/C composite. This research expands the exploration of applying composites prepared by molten salt synthesis for the microwave absorption field.
