Synthesis of pyrochlore free PMN-PT powder by partial oxalate process route

Realization of device quality PMN–PT ceramics using modulated heating method

“…(1À x)[Pb(Mg 1/3 Nb 2/3 )O 3 ]-(x)[PbTiO 3 ] (PMN-PT) ceramics belongs to the category of relaxor ferroelectrics, and PMN-PT is a smart material for piezoelectric applications [1][2][3]. It is an offshoot of the complex perovskite Pb(Mg 1/3 Nb 2/3 )O 3 (PMN), discovered by Smolenskii and Agronovskaya in 1958 [4].…”

Magnesia induced coagulation of aqueous PZT powder suspensions for direct coagulation casting

“…The formation of this surface complexes results in strong adsorption of ammonium poly(acrylate) on PZT particles. This is further evidenced from the fact that ammonium poly(acrylate) dispersed aqueous suspensions of another lead containing ceramic powder, PMN-PT (in house prepared), also showed coagulation characteristics similar to the PZT suspensions upon the addition of MgO [25].…”

Phase development and electrical properties of Pb(Mg1/3Nb2/3)O3‐PbTiO3 ceramics prepared by partial oxalate route

“…The PMN‐PT ceramics with different compositions ( x = 0.2, 0.29, 0.31, 0.33, 0.36, 0.38, 0.4) were prepared by the partial oxalate route . Analytical grade reagent Pb(CH 3 COO) 2 · 3H 2 O (>99.0%), MgO (>99.0%), Nb 2 O 5 (>99.5%), TiO 2 (>98.0%), and H 2 C 2 O 4 · 2H 2 O (>99.5%) were used as raw materials.…”

“…Furthermore, as the content of PT lies in the vicinity of the morphotropic phase boundary (MPB), PMN‐PT exhibits enhanced microstructure and superior dielectric and piezoelectric properties . This behavior makes the material very attractive for commercial applications in multilayer ceramic capacitors, high‐resolution medical imaging, and displacement transducers .…”
