Abstract
Ni-Zn ferrite/SiC sintered composite was prepared as electromagnetic wave absorber through pre-ceramics method and subsequent annealing at 1273 K. Amorphous SiC particles dispersed uniformly in Ni-Zn ferrite matrix and the density of the composites decreased with increasing the amount of SiC particles. The absorption characteristics of the sintered composite were found to depend upon the amount of SiC particles. The matching frequency of the composites shifted toward higher frequency, from about 100 MHz to 1 GHz, with increasing the amount of SiC particles.
