Wave Absorption and Thermal Stability of Nickel Coated Al2O3 Core-shell Composite Powder
College of Materials Science &Technology, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China
As a composite cermet material, the nickel coating on the surface of alumina particles has important application value because of its good electromagnetic wave absorption performance. In this study, nickel was deposited on the surface of alumina nanopowders by hydrothermal method and sintering method. The results show that the XRD results of nickel alumina show that Ni-Al2O3 nanoparticles has FCC face-centered cubic structure. The grain size is about 50 nm. The absorption characteristics of electromagnetic waves were measured at 2-18 GHz by HP 8722 es microwave network analyzer. The results show that Ni-Al2O3 nanoparticles has certain wave-absorbing properties.
