Abstract

The objective of this research was to characterize the dielectric and induced piezoelectric properties of W⁶⁺-doped, 0.87 Pb(Mg_1/3Nb_2/3)O₃ - PbTiO₃ relaxor ferroelectrics. The induced kt's depended strongly on the W⁶⁺ amount and electric field, maximizing at a value of 0.58 for an applied field of 6 kV/cm and a 1% doping level. In addition, only slight variations in the sintering temperature (±10°C) had a pronounced effect on the properties, decreasing the k_t by as much as 10%.
