摘要	3D reticulated ceramics (3DRCs) with the composition containing SrFe12O19-SiC-TiO2 were prepared by a replication process with polyurethane sponges as the template in ceramic slurry. The electrical conductivity, dielectric and magnetic parameters of 3D reticulated ceramics (3DRCs) were measured with changes in cell size of the sponges, contents in the slurry and sintering temperature in this paper. Discussions about the influential factors of those parameters were focused on their electrical conductivity. The experimental results indicated that the electrical conductivity of 3DRCs raised with the increase of cell size, SiC/SrO(.)6Fe(2)O(3) with weight ratio and sintering temperature. X-ray diffractions and SEM were used to investigate the relationship between electrical conductivity and sintering temperature. Deoxidizing reactions of SrO(.)6Fe(2)O(3) caused the increasing electrical conductivity. The real part of permittivity (epsilon') and imaginary part of permeability (mu") raised with the increase of electrical conductivity (sigma). The imaginary part of permittivity (epsilon") has a maximum at 10(0) S/cm with the increase of a, and the real part of permeability (mu') changes slightly with the increase of sigma. When sigma is at the range of 10(-4) S/cm to 10(0) S/cm (a semi conductive state), both the imagine part of permittivity and permeability raises with increasing sigma, therefore, the 3DRCs present their high electromagnetic loss properties.
