The dielectric behavior of the composites was studied in the frequency range 102 – 4 ϫ 107 Hz. The results show that the dielectric constant increased remarkably with the Ti3SiC2 concentration, when the Ti3SiC2 concentration was close to percolation threshold. This may be attributed to the critical behavior of the dielectric constant near the percolation threshold as well as to the polarization effects between the clusters inside the composites. © 2005 American Institute of Physics.
