Dielectric Characteristics of a Relaxor 0.9PMN-0.1PT Synthesized With Hot and Cold Pressing


 Two different processing methods were employed, hot pressing and cold pressing for fabricating Pb(Mg1/3Nb2/3)O3-PbTiO3 (PMN-PT) ceramic bulk samples, which could be used in the applications of electromechanical actuators in smart material system and structures. The dielectric constant, dielectric loss of these samples versus frequency and temperature were measured and analyzed.
