Abstract

Highly textured PMN-28PT (0.72Pb(Mg_1/3Nb_2/3)O ₃-0.28PbTiO₃) ceramics were produced by templated grain growth on <001> oriented platelet-shaped SrTiO₃ template particles with an aspect ratio of 10-15. The templates were aligned in PMN-28PT matrix powder via tape casting and fired in an O₂-PbO atmosphere at 1150°C for up to 15 h. This resulted in textured ceramics with a 40 micrometer grain size and without residual templates. The volume fraction of textured material (f) and the orientation parameter (r) were quantified by fitting X-ray diffraction rocking curve data to the March-Dollase equation. Processing conditions were optimized to achieve the best possible values of f and r for the chosen templates and matrix powder. A texture fraction of at least 81 vol% and an orientation parameter of 0.2 were achieved when all random matrix grains were consumed (a perfect textured ceramic would show a texture fraction of 100 vol% and an orientation parameter of 0).
