The chemical structural formula of PMN-PT is (1-x)[Pb(Mg1/3Nb2/3)O3]-x[PbTiO3].The PMN-PT is formulated to exhibit high piezoelectric coefficient, large electric-mechanical coupling coefficient, high dielectric constants and low dielectric losses. As a rule, the piezoelectric coefficient is higher than PZT ceramics, which results in improving bandwidth, sensitivity and source level in applications. We could provide high quality PMN-PT crystals with the diameter of 2 inches for a broad range of applications. Reference Capability of PMN-PT Crystal Properties Dependence on Crystallographic Direction of PMN-PT Crystal These typical values are provided for design information only. Standard tolerances are approximately+/-20% of these values. Material properties are measured according to standard IEEE and DOD definitions and measuring techniques. All data shown represent nominal characteristics (20 ℃) 24 hours after polarization. Additional photos
