The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis

Physical Properties of Porous Pure and Zr/Sn-Doped Nanocrystalline BaTiO3 Ceramics

“…The increase in Remnant polarization is due to the increase in the dielectric property and decrease of the porosity of the sample with an increase in Sn doping [56]. The performance parameter of BT is very close to that of the reported values (P s of 2.0 μC/cm 2 , E c of 5 kV/cm) for the ceramic sample [57] and lower than the one obtained by the same synthesis route (P r of 2.0μC/cm 2 , and coercive field (E c ) of 1060 V/cm) [35]. Polarization reversal of a ferroelectric domain is much easier inside a larger grain the comparison to that in a smaller grain [58].…”

“…The polarization-electric field (P-E) hysteresis (Figure 2a). This is because the (200) and (002) peaks are not split [33] as reported by other workers [34,35], whereas it is tetragonal for Ba(Ti 0.96 Sn x Zr 0.04-x )O 3 (x = 0.02À0.04) ( Figure 2b-d) with the splitting of the (200) and (002) characteristic peaks which are in agreement with the joint committee on powder diffraction standards (JCPDS file no.98-00-2020), similar result was obtained for x = 0.04 using conventional method by other workers [36]. It can also be noticed from Figure 2a-d that the positions of the diffraction peaks of the ceramics shift slightly to lower angle with increasing Sn content in the range of 2θ from 44 to 46.5 o .…”

Fabrication of barium titanate nanoparticles/poly (methylmethacrylate) composite films by a combination of deposition process and spin-coating technique

“…Titanate ceramics like the BT is facing at some problems. One is that the titanates are required to be crystallized by annealing at high temperature to make them have dielectric characteristics [10,11]. A lot of energy is consumed through the high temperature annealing, which provides the large load to environment.…”

Phase Formation and Microstructure of BaTiO3Ceramics Prepared by Direct Current Arc Discharge Process

“…The small absorption band at 3425 cm ¡1 can be interpreted as hydroxyl groups by weak hydrogen bonds with OH groups of BaTiO 3 surfaces. The band around 1637 cm ¡1 can be assigned to the H-O-H bending of the coordinated water which is absorbed at the BaTiO 3 surface and comes from ambient circumstances [14]. The Bands in the lower wavenumbers range (400-1000 cm ¡1 ) are ascribed to Ti-O vibrations [15].The absorption bands at 1091, 1050, 878 cm ¡1 are related to Ti-O-Ba bonds.…”
