As a novel kind of piezoelectric materials, relaxor-based ferroelectric single crystals exhibit ultrahigh piezoelectric performances, which surpass largely those of conventional PZTs piezoelectric ceramics. Our company can provide three generations of relaxor-based piezocrystals, i.e. Pb(Mg1/3Nb2/3)O3-PbTiO3 (abbreviated as PMN-PT or PMNT), Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (abbreviated as PIN-PMN-PT or PIMNT) and Mn doped Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 (abbreviated as Mn:PIN-PMN-PT or Mn:PIMNT) in large scale. High quality, large size and uniform crystals are available, which can satisfy various ultrasonic transducers in medical ultrasonic imaging, nondestructive examination and energy harvesting, solid-state actuators and composites such as magnetoelectric ones. The crystals have also good electro-optic properties and excellent pyroelectric properties, which can find application in the fields of electro-optic modulators in optical communications and pyroelectric devices in infrared detection and so on.

The main performance specifications are presented in the following tables. Various cut-type samples can be offered. Please contact us by email to discuss your requirements.
