Perovskite structure development in (Ba)Ti-substituted Pb(Zn1/2W1/2)O3 and dielectric properties

Structure development and dielectric properties of Zn‐doped Pb([Mg,Fe],W)O3 perovskite ceramics

“…When the structure field map of electronegativity difference vs tolerance factor is considered, however, the perovskite structure PZW appears to be highly unlikely to form. Actually, attempts to synthesize the compound have only been marginally successful, with only the mixed states of Pb 2 WO 5 and ZnO resulting instead. It should be noted that the formula of Pb(Zn 1/2 W 1/2 )O 3 and the acronym PZW used in this article only denote the composition, and not necessarily implying the formability of perovskite structures.…”
