Abstract

Ceramics of lead magnesium niobate-lead titanate solid solution, 0.90Pb(Mg_1/3Nb_2/3)O₃-0.10PbTiO₃ (PMN-PT), have been synthesized by a new room temperature sol-gel route, using polyethylene glycol-200 (PEG) and methanol mixture as solvent. The use of a triol molecule, 1,1,1-tris(hydroxymethyl)ethane (THOME), which is known to serve as a complexing agent used in binding together the metal ions in the precursor solution, has been shown to give good dielectric and ferroelectric properties (ε_max′=33,000 at T_max=40°C and P _r=18μC/cm² at room temperature) for the stoichiometric PMN-PT ceramics sintered at 1050°C. A 5mol% excess of lead in the sol-gel process without THOME led to an improvement in the formation of the perovskite phase but a degradation of the dielectric properties with ε _max′=10,000 and P_r=11μC/cm² only.
