The effect of using Ba 2+ to modify the structure and dielectric piezoelectric properties Pb (1− x ) (Mg 1/3 Nb 2/3 m (Zn y (Ni n Ti z O 3 ( = 0–0.15) ceramics near morphotropic phase boundary has been investigated. It is found that increasing content leads a sequence structural transformations from heterophase state (tetragonal pseudocubic phases) cubic via an intermediate phase. evolution (sequences transformations: normal ferroelectric →relaxor → paraelectric) shown. stated with...
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....
Quasibinary section solid solutions of a four-component system the (1-x)(Na0.5K0.5)NbO3-xPb(Ti0.5Zr0.5)O3 composition, based on compositions with fundamentally different physical responses (Na, K)NbO3(KNN), Pb(Ti, Zr)O3 (PZT), have been produced by two-step solid-phase synthesis followed sintering using conventional ceramic technology. The features their structural formation revealed, phase diagram equilibria has constructed, correlation relationships composition ‒ structure microstructure...
Abstract The polycrystalline samples of Bi 1-x A x FeO 3 (A=La, Nd; x=0-0.2) were prepared by a conventional solid-state reaction method. effects varying the Nd and La doping concentration on crystalline structures, magnetic properties temperature antiferromagnetic phase transition T N compounds have been investigated. It is found that resulted in sequence structural transitions destruction space modulated spin structure near x=0.15 these materials. dependences ac-susceptibilities obtained....
We investigated and presented our results for the dependence of characteristics crystalline grain structures PCR-13 material (based on lead zirconate titanate (PZT) system), which was sintered in various ways, regulations its preparation. The data from microfluorescence analysis surface ceramic materials were provided, allowed us to state that micro X-ray fluorescence spectrometry (MICRO–XRF), supplemented by mathematical statistics, allows trace even small changes chemical composition...
