Complete Thermodynamic Phenomenologies for Lead Zinc Niobate: Lead Titanate (PZN:PT) and the Lead Magnesium Niobate: Lead Titanate (PMT:PT) Single Crystal System

摘要

This final report covers the work carried out under ONR Grant NOOOl4- 99-0530 developing the Thermodynamic Phenomenology to describe the properties of Lead zinc niobate: Lead titanate (PZN:PT) and Lead magnesium niobate: Lead titanate (PMN:PT) single crystals, over the period May 1, 1999 to June 30, 2001. Early into these studies it became apparent that the solution grown PZN:PT crystals at compositions close to the morphotropic phase boundary were more homogeneous with lower concentration gradients than the then available Bridgeman grown PMN:PT so the major effort was focused upon the PZN:PT family.
