“Background Ceramic materials with high dielectric permittivity (ϵ′) have been intensively studied because of their potential for multilayer ceramic capacitor applications.

The dielectric materials used in these devices must exhibit a high ϵ′ with very low loss tangent (tanδ). They also need to have a high breakdown voltage to support high-energy density storage applications. The energy density (U) performance of capacitors can be expressed as , where E b is electric field breakdown strength [1]. Recently, dielectric ceramics homogeneously filled with metallic particles have been of considerable scientific and technological interest. This is due to their greatly enhanced dielectric response as well as an improved tunability of ϵ′ [2–11]. Generally, ϵ′ increases rapidly in the region of the percolation threshold (PT) [4, 9]. For the Ag-Ba0.75Sr0.25TiO3 composite [9], the large increase in ϵ′ was selleck chemicals llc suggested to result from the percolation effect. Improved tunability of Ba0.
