Solid-State Crystal Growth (SSCG) Method for PMN-PT and PMN-PZT
Ceracomp Co. Ltd. announces the release of piezoelectric PMN-PT and PMN-PZT single crystals, which are fabricated by the costeffective solid-state crystal growth (SSCG) method. Their excellent dielectric and piezoelectric properties make them the best candidates for transducers, actuators, and single crystal-polymer composites.
PMN-PT and PMN-P2T single crystals(<001> &<011>) are available with lateral dimensions up to 40 mm. High TC PMN-PZT single crystals (TC>200°C) are also available by request.
