“…In the present case, Sb 2 O 3 -doping has been shown to produce a linear reduction in T C . In Figure 8, it is clear that the ε 33 T (max) sharply decreases as the content of Sb 2 O 3 increases and the dielectric peaks broaden around T C , which is similar to previous observations [13,37]. Similarly, Dutta et al also explained that the broadening of the dielectric peak and variation of ε 33 T (max) could be attributed to the variation of grain size and some kinds of structural disorder [20].…”

Abstract:The effects of doping antimony oxides (Sb 2 O 3 /Sb 2 O 5 ) on the ferroelectric/piezoelectric and energy-harvesting properties of 0.99Pb(Zr 0.53 Ti 0.47 )O 3 -0.01BiYO 3 (PZT-BY) have been studied. The feasibility of doping Sb 2 O 3 and Sb 2 O 5 into the PZT-BY ceramics has also been compared by considering factors such as sintering condition, grain size, density, and electrical properties etc. This work discusses a detailed experimental observation using Sb 2 O 3 , because Sb 2 O 5 is relatively expensive and does not follow the stoichiometric reaction mechanism when doped in PZT-BY. The Sb 2 O 3 -doped specimens were well sintered by oxygen-rich sintering and reached a maximum density of 99.1% of the theoretical value. X-ray diffraction (XRD) analysis showed a complete solid solution for all the specimens. Scanning electron microscope (SEM) observation revealed that the addition of Sb 2 O 3 inhibits grain growth, and exhibits a denser and finer microstructure. These values are high compared to recently reported works. Therefore, Sb 2 O 3 -doped PZT-BY ceramic could be a promising candidate material for the future study of power-harvesting devices.

“…It is evident that the value of K 33 T ( max ) sharply decreases as the content of BY increases to 0.02 mol, and the dielectric peak broadened rather than sharpening around T C , which is one of the characteristics of disordered perovskite structure with diffuse phase transition. This broadening is believed to be due to the compositional fluctuation [31] leading to a microscopic heterogeneity in composition, and thus, to a distribution of different local T C , caused by the appearance of a second phase [BY]. It is well known that cubic phase addition to PZT reduces T C , but in the PZT system with BY added, T C increased.…”

In this work, the effect of BaTiO3 (BT) addition on structural, dielectric and electrical properties of CaCu3Ti4O12 (CCTO) ceramic was investigated. Ceramic samples with the chemical formula (1-x)CaCu3Ti4O12 -xBaTiO3, (1-x)CCTO-xBT, (x = 0.00, 0.10, 0.20, 0.30, 0.50 and 1.00) were synthesized by solid state route. The structural studies carried out by X-ray diffraction technique and showed that the perovskite structure cubic and tetragonal phases were formed without any other impurity phases. The addition of BaTiO3 into CCTO system lowered the last crystallite size to about 52 nm and increased the dielectric constant by four orders compared to pure CCTO. Moreover, the results of the complex impedance analyses of (1-x)CCTO-xBT ceramics samples confirmed the presence of non-Debye type of relaxation phenomenon and exhibited a negative temperature coefficient of resistance behaviour.Keywords: Ceramics, Barium titanate, Raman spectroscopy. Chemistry; Vol. 29, No. 8 (2017), 1811-1816 a mixture CCTO and BaTiO3 characteristics. In the present work we are reporting the synthesis of (1-x)CCTO-xBT by solid state reaction route. The structural, dielectric and electrical properties of (1-x)CaCu3Ti4O12-xBaTiO3 ceramics (where x = 0.00-1.00) were investigated. Asian Journal of EXPERIMENTALThe (1-x)CCTO-(x)BT samples were synthesized by means of a conventional mixed oxide route. High-purity oxides and carbonates; CaCO 3 (99.8 %) CuO (purity, 99 %), TiO 2 (purity, 99.95 %) and BaCO 3 (purity 99.5 %) (All Sigma Aldrich chemicals, USA) were used as starting materials.Synthesis of (1-x)CaCu 3 Ti 4 O 12− − − − −xBaTiO 3 : The powders were weighed in stoichiometric proportion and milled for 1 h. Then the slurry was dried in an oven at 80 °C. The calcinations processes of CCTO and BaTiO 3 powders were carried at 1050°Cand 1100 °C for 4 h, respectively. The synthesized powders were mixed in acetone according to the formula (1-x)CCTO-(x)BT for 2 h and dried at 400 °C for 1 h, after that the powders were crushed in agate mortar and pressed into pellets of about 12 mm diameter and 1.5 mm thickness. Then, the pellets sintered at 1050°C for 8 h and left at room temperature. The samples surfaces were coated by silver paste to serve as poles for the electrical measurements uses. Characterization of (1-x)CaCu3Ti4O12− − − − −xBaTiO3XRD analysis: The crystal structure of (1-x)CCTO-xBT was determined by using an X-ray diffractometer with a scanning rate of 0.02°/min for 2θ range 20°-80° by employing CuKα radiation wavelength λ = 1.5406 Å (diffractometer system = XPERT-PRO) under the conditions of 40 KV and 30 mA.Raman spectroscopy analysis: A micro Raman spectrometer, equipped with an excitation source of monochromatic with wavelength of 410 nm, was used to study the relationship between Raman lines and different types of atomic motions of CCTO and BaTiO3 in the (1-x)CCTO-xBT ceramics. After the sample processing, Raman spectra was collected at room temperature.Dielectric measurements analysis: The electrical properties of the ceramics were measu...
