A complete solid solution between relaxor ferroelectric Pb(Fe 2/3 W 1/3 )O 3 (PFW) and ferroelectric PbTiO 3 (PT), (1Ψx)PFW+xPT, was synthesized by a B-site precursor method and characterized by X-ray di4raction, di4erential scanning calorimetry, and dielectric measurements. A phase diagram between
Kinetic data analyses on the crystallization behaviour of amorphous lead iron tungstate (PFW) were carried out. A low value of the glass transition/melting point ratio (0.52) and a high value of the frequency factor (2 x 1037s -I) of the first crystallization exotherm may indicate a high degree of m
