Study on Preparation and Dielectric Properties of Nano Ni/SiC Composite Particles

Abstract:

In order to alleviate the glomeration of nanometer (SiC)p and improve its compatibility and performance, the chemical plating method was applied to get high-quality surface modification, and achieve the Ni/SiC composite particles. The dielectric and absorbing properties of the Ni/SiC particles were studied. The results showed that the modified SiC particles is nearly spherical, homogeneous morphology, and has a distinct core and shell parts. The different contrast of the shell indicated that more Ni is deposited on the (SiC)p surface, and the silicon carbide-nickel core-shell structure is formed. The dielectric constant, dielectric loss and magnetic permeability of the Ni/SiC composite particles have significant improvements compared with those of the original one. The dielectric constant rises about 24%, and R reaches -25.15dB when magnetic permeability up to 16.11GHz.
