Abstract

Electrical property of the composite made with resin as a binder resin and SiC and/or Fe₃O₄ as filler has been studied. It is found that the critical volume fraction of Fe₃O₄ in the composite made with resin and Fe₃O₄ differs from that in the composite made with resin, Fe₃O₄ and SiC. The nonlinear behavior of resistivity for electric field is controlled by percolating paths formed by SiC particles. It. is also found that the appearance of the non-linear property shifts to higher electric fields by adding Fe₃O₄ as a filler to the composite made with resin and SiC particles
