摘要：
Pb(M,Nb-1/3(2/3))O-3-PbTiO3 solid solution ((1-x)PMN-xPT) tape cast ceramics have been prepared by horno-epitaxial templated grain growth (HTGG) using Cubic 0.75PMN-0.25 PT single crystal seeds as template (a few wt%) and x=0.35 nanoparticles for the ceramic matrix. Raman imaging studied representative medium and highly textured ceramics. On the base of a previous study which has shown that the Raman peak centre of gravity depends on the solid solution composition whereas peak intensity is correlated to the unit-cell distortion, Raman imaging shows that the final composition and structure is very close to that of the matrix.
