This work presents the results of study electrophysical properties composite polymer ceramics (1[Formula: see text][KNN-LTSN]–[Formula: text]PVDF at [Formula: text] = 25 vol.% and text]= 50 in temperature range 20–160[Formula: text]C frequency 2 × 10 1 –2 6 Hz. The concentration dependence piezomodules studied materials has been analyzed as a function temperature. X-ray measurements have also carried out. A model description revealed dielectric parameters dispersion material is presented....
This paper is focused on the comparison of results various approximation models describing frequency dependences dielectric constant [Formula: see text] and text], tangent loss angle tg[Formula: electrical conductivity nonlinear dielectrics. The classic ferroelectric material PZT system with was chosen as object study. Based analysis temperature-frequency “empirical” parameters a regularity has been revealed that allows them to be calculated. A new relationship established through parameter...
Ceramics of binary systems solid solutions (1 - x)NaNbO3 xCa2Nb2O7 and xSr2Nb2O7 with non-isostructural extreme components were prepared by the solid-phase reactions technique following sintering using conventional ceramic technology. It was found that ceramics x ≤ 0.2 have a perovskite structure. Layered type structure predominates in concentration range < 1. Phase diagrams both at room temperature been determined area. shown this area contains two regions different crystal structures...
ПРОГНОЗИРОВАНИЕ СВОЙСТВ БЕССВИНЦОВЫХ ПЬЕЗОКЕРАМИК И МОДИФИКАЦИЯ КОНСТРУКЦИИ ВИБРОДАТЧИКОВ НА ОСНОВЕ СВИНЕЦСОДЕРЖАЩИХ КОМПОЗИЦИЙ
This work presents the results of studying electrophysical properties [Formula: see text][Formula: text]O 3 solid solution in range temperatures text] = 26–400[Formula: text]C and frequency 10 2 –10 5 Hz. A model description revealed dispersion dielectric parameters material is made. The nonclassical modified Havriliak–Negami written for complex electrical conductivity was used as an approximation model. It shown that application this almost exactly describes behavior constant...
Abstract The effect of polyaniline additives on the dielectric and piezoelectric properties a composite based multi-component system sodium-potassium niobate was studied in paper. behavior characteristics, electromechanical studied. critical concentration influencing formation an connection between ferroactive inclusions determined.
