“…51,52 In particular, Haun et al has provided estimates of Q 11 and Q 12 for PZT as a function of PbTiO 3 content, 49 where η varied from approximately 0.30 to 0.48, depending on composition. In the vicinity of the MPB, however, Haun et al found that η = 0.48.…”

Effect of grain size on domain structures, dielectric and thermal depoling of Nd-substituted bismuth titanate ceramics

“…10 This can be regarded as a consequence of the fact that internal stresses tend to favor the stabilization of the paraelectric phase by suppressing the spontaneous deformation and spontaneous polarization, resulting in a lower Curie point T c . 28 The d 33 of all ceramics were thermally stable when the annealing temperature was below 0.6T c . When the annealing temperature is higher than 0.6T c , the d 33 of ceramics with smaller grain sizes is less thermally stable than that of ceramics with larger grain sizes, which can be attributed to the higher stresses in ceramics with smaller grain size.…”

Indentation-induced stress distribution and pressure effect on the resistivity of YSZ

“…Electrochemical analysis of conducting and dielectric materials under high pressures has received considerable attention in view of various interesting properties such as crystallographic phase transition, shifts of temperatures (Curie point/superconducting transition) and changes in phonon modes [1][2][3][4][5][6][7][8][9]. For ionic conductors, conductivity, , is expressed as  = 0 exp {-(E + pV) / RT }, (1) where 0 is a pre-exponential factor [S/cm], E is the activation energy [J/mol], p is the pressure [Pa], V is the activation volume [cm 3 /mol], R is the gas constant [J/mol·k], and T is the absolute temperature [k].…”
