Orientation distribution and fiber texture of highly oriented piezoceramics (1 - X)PbMg1/3Nb2/3O 3-xPbTiO3 system

Abstract : Textured (1 - x)PbMg1/3Nb2/3O3-xPbTiO 3, (PMN-xPT), ceramics were synthesised by the homo template grain growth (HTGG) technique using PMN-PT nanoparticles and cubic single crystals seeds (templates). The orientation of the templates was obtained during tape casting. Sintering was performed under controlled O2/PbO partial pressure. The fraction of textured ceramics was estimated by the Lotgering method at RT and above Tc. Textured tape cast ceramics display a quasi complete (001) texture (f = 0.99) in the cubic phase. The (011) pole figure reveals a (001) fibre texture in accordance with the optical observation. The texture was obtained in all volumes of ceramics and only a small orientation distribution was observed (andlt;6°).
