4.3 Ceramic–Ceramic Composites. Comparing with dielectric polymer and polymer-based composites, ceramic–ceramic composites lack flexibility and have low breakdown strength. This is the main reason why the energy performance of ceramic–ceramic dielectric composites has reached a plateau over the past years.
The downside to ceramic capacitors'' relatively inert "steel and stone" construction is that no self-healing mechanism is present; stresses resulting in dielectric breakdown tend to result in irrecoverable damage to the device, and substantive safety factors must thus be built in as additional dielectric thickness, since weak spots in the ...
