Abstract: Systems and methods are provided for preparing multi-component ferroelectric crystals (e.g., PMN-PT, amongst others) having piezoelectric properties. The crystals are fabricated using a system that employs multiple heaters and sensors that are located along the length of a crystal growth chamber. The heaters are controlled in concert, via a feedback system, to produce a temperature profile having a gradient that effectively moves along the length of the chamber, to suitably effectuate crystallization throughout the chamber, without need for the chamber to translate relative to the heater(s). During the crystallization process, the contents of the chamber may be mixed and/or homogenized via suitable agitation thereof, resulting in a multi-component ferroelectric crystal of desirable quality.
