Textured ($1-x$)PbMg1/3Nb2/3–$x$PbTiO3, (PMN–$x$PT), 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$) in the cubic phase. The (011) pole figure reveals a (001) fibre texture in accordance with the optical observation. The texture was obtained in all volumes of ceramics and only a small orientation distribution was observed (${<}6$°).
