Raman Imaging and Thermal Expansion of Highly Textured Pb(Mg1/3Nb2/3)O3-PbTiO3 Piezoelectric Ceramics Philippe Colomban, Mai Pham-Thi1 Ladir, UMR 7075 CNRS & Université Pierre & Marie Curie, 2 rue Henry-Dunant, 94320 Thiais, France 1 Thales Research & Technology France, 91404 Orsay, France ABSTRACT PMN(PZN)-PT single crystals exhibit unique electromechanical properties when oriented and poled along the direction. While expensive crystal growth techniques are advancing slowly, it is of great practical importance to develop an alternative low-cost production method based on strongly oriented or textured ceramics. We present here the thermal expansion, dielectric properties and Raman spectroscopy study of Pb(Mg1/3Nb2/3)O3-PbTiO3 solid solution ((1-x)PMN-xPT, 0.2
