Evolution of local heterogeneity towards flat free energy landscape: Optimization of piezoelectric response in PNN-PZ-PT at morphotropic phase boundary

Chemical Physics Impact
A precisely specified compositional landscape of two distinct ferroelectric systems – morphotropic phase boundary (MPB) – possesses ultrahigh piezoelectricity, where generically a flat energy profile is favoured under thermodynamic consideration.

Morphotropic Phase Boundary (MPB) of Tungsten Bronze Type New Compounds (Pb1-xLa2x/3)5Nb10O30 (X=0.0-0.50).

Journal of the Ceramic Society of Japan, 2000
The structural and ferroelectric properties of new compounds (Pb1-X2+La2X/33+)5Nb10O30 (X=0.00-0.50) were studied with respect to La3+ ion substitution of Pb2+ ion in Pb5Nb10O30 having the orthorhombic tungsten bronze structure. Phase identification shows that the structure of compounds will change from orthorhombic to tetragonal symmetry along with ...

High piezoelectric performance and temperature dependence of ferroelectric and piezoelectric properties of Bi(Mg0.5Zr0.5)O 3-PbTiO3 near morphotropic phase boundary

, 2014
According to consideration on the average radius of B-site cation of BiMeO3, we reported that the Bi(Mg0.5Zr 0.5)O3-xPbTiO3 compound at the morphotropic phase boundary (MPB) of x=0.58 possesses a piezoelectric coefficient d 33 as high as 306 pC/N.

Annealing-Dependent Morphotropic Phase Boundary in the BiMg0.5Ti0.5O3–BiZn0.5Ti0.5O3 Perovskite System [PDF]

, 2022
The annealing behavior of (1-x)BiMg0.5Ti0.5O3–xBiZn0.5Ti0.5O3 [(1-x)BMT–xBZT] perovskite solid solutions synthesized under high pressure was studied in situ via X-ray diffraction and piezoresponse force microscopy.
