Research abstract
Parke Mathematical Laboratories, Inc. will develop a method for growth of lead magnesium niobate- lead titanate (PMN-PT) solid solution single crystals doped with barium or lanthanum. These crystals will bring significant advances to the state-of-the-art of PMN-PT transducer technology which now depends upon ceramic materials for which the polycrystalline microstructure limits the coupling coefficient. In Phase I, crystal growth will be based on conventional techniques for the purpose of demonstrating feasibility, evaluating the relevant crystal growth parameters and obtaining samples for characterization and engineering development. Based on the information obtained, a design will be developed for scale-up and for non-conservative growth of homogeneous solid solutions.
