Abstract
The hard-to-synthesize lead-based zinc-bearing trio of Pb(Zn1/3Ta2/3)O3, Pb(Zn1/3Nb2/3)O3, and Pb(Zn1/2W1/2)O3 (PZT, PZN, and PZW) were investigated to understand their structural stability and phase formation. A structure field map is used to discuss the capability of the trio compositions and combinations thereof, to form the perovskite structure, with PbTiO3(PT) introduced as a perovskite stabilizer. We identified the potential omission of the (111) reflections in two International Centre for Diffraction Data (ICDD) sets of a complex-rutile structure, [(Zn1/3Ta2/3)1/2Ti1/2]O2 and [(Zn1/3Nb2/3)1/2Ti1/2]O2, and suggest that the intensities of the latter compound need to be re-examined. The perovskite structure started to develop at different fractions of PT, depending upon the species of the trio: PZN required the smallest amount of PT (< 20 mol%), whereas PZW required the greatest (≤ 80 mol%). The perovskite-stable composition area was the widest in PZT-PZN-PT and narrowest in PZW-PZT-PT, indicating the comparative ease/difficulty of perovskite formation among the trio compositions. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature.
