Dielectric and piezoelectric properties of neodymium oxide doped lead zirconate titanate ceramics

Abstract

The dielectric and electromechanical properties of lead zirconate titanate [Pb(Zr, Ti)O 3 ] ceramic added with neodymium oxide have been systematically studied employing the vector impedance spectroscopic (VIS) technique. The specimens were prepared using the mixed oxide route by adding different mol% of Nd 2 O 3 (0⋅ ⋅1 to 7 mol%) in [Pb(Zr, Ti)O 3 ] near morphotropic phase boundary. Piezoelectric equivalent circuit parameters R, L, C a in series and C b in parallel have been determined by simulating /Z/ and Θ Θ plots. Electromechanical coupling coefficients and strain constants for the radial modes show a peak at about 3 mol%, the dielectric constant peaks at about 1 mol% and voltage constants peak at about 0⋅ ⋅75 mol% of Nd 2 O 3 .

Dielectric, ferroelectric and piezoelectric studies of neodymium-modified PLZNT ceramics for sensor and actuator applications

“…Our results agree very well with Thamjaree et al [19]. The results are comparable with the literature [16][17][18][19][20][21][22]. Fig.…”

“…It has been observed that electromechanical properties enhance with Nd dopant concentration. As per Singh et al [21], electromechanical parameters of Nd-doped PZT (54/46 Zr/Ti ratio near MPB) significantly enhanced. In our study, maximum values of d 33 (549 pC/N) and k p (0.541) are found in 1 mol% Nd-doped PLZNT ceramic.…”

Phase formation and microstructure of Nd+3 doped Pb(Mg1/3Nb2/3)O3 prepared by sol–gel method

“…Effects of rare earth elements (RE) doping on the phase formation and electrical properties of piezoelectric ceramics such as barium titanate and lead zirconate titanate are well studied [12][13][14][15]. The effect of RE addition on the PMN system has also been studied in the literature to a degree.…”

Synthesis and characterization of neodymium oxide nanoparticles

“…5. It appears that the as-prepared sample is well-crystallized Nd(OH) 3 , which upon further heat treatment transformed into cubic neodymium oxide. The particles of neodymium hydroxide (seen in Fig.…”

“…as phosphors providing yellow-to-violet upconversion emission [1]), as components for advanced materials (e.g. high temperature ceramics and superconductors) [2,3], as components of catalytic systems (oxidative coupling of methane, N 2 decomposition, dehydrogenation of alcohols, high-temperature processes) [4][5][6] and in many special applications (among others, to simulate the actinide oxides during testing the new materials as a host matrix for long life nuclear wastes [7]). Moreover, thin films of Nd 2 O 3 are of interest for many other purposes such as optical antireflection coatings, gate insulators and protective coatings.…”
