The hard-to-synthesize lead-based zinc-bearing trio of Pb(Zn_1/3Ta_2/3)O₃, Pb(Zn_1/3Nb_2/3)O₃, and Pb(Zn_1/2W_1/2)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, [(Zn_1/3Ta_2/3)_1/2Ti_1/2]O₂ and [(Zn_1/3Nb_2/3)_1/2Ti_1/2]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.

Pb（Zn _1/3 Ta _2/3）O ₃，Pb（Zn _1/3 Nb _2/3）O ₃和Pb（Zn _1/2 W ）难合成的铅基含锌三重奏_对1/2）O ₃（PZT，PZN和PZW）进行了研究，以了解其结构稳定性和相形成。使用结构场图来讨论三者组合物及其组合形成钙钛矿结构的能力，并引入PbTiO ₃（PT）作为钙钛矿稳定剂。我们在复杂金红石结构的两个国际衍射数据中心（ICDD）组中确定了（111）反射的潜在遗漏，[（Zn _1/3Ta _2/3）_1/2 Ti _1/2 ] O ₂和[（Zn _1/3 Nb _2/3）_1/2 Ti _1/2 ] O ₂，建议后者的强度为重新检查。钙钛矿结构开始在PT的不同部分上发展，这取决于三重化合物的种类：PZN需要最小量的PT（<20 mol％），而PZW需要最大量的PT（≤80 mol％）。钙钛矿稳定的组合物面积在PZT-PZN-PT中最宽，在PZW-PZT-PT中最窄，表明三者组合物中钙钛矿的形成相对容易/困难。
