Abstract
The dielectric properties of Na0.5Bi0.5TiO3 (NBT)-based composites incorporating silver particles prepared by sintering at a low temperature of ∼900°C arc reported. The dielectric constant increases with the amount of metal silver particles in the measured frequency range (150 Hz to 1 MHz), and could be enhanced up to ∼20 times higher than that of pure NBT ceramics, which was ascribed to the effective electric fields developed between the dispersed particles in the matrix and the percolation effect. Further investigation revealed that the dielectric constant of the composites has weak frequency and temperature dependence (-50°C to +50°C).
