Crystal structure refinement of co-doped Ba 0.88 Ca 0.12 Ti 0.975 Sn 0.025 O 3 ceramic

Investigation of Er3+ Ions Reinforced Zinc-Phosphate Glasses for Ionizing Radiation Shielding Applications

“…Hence as the Cd content decreases and Er increases in the glasses, FNRC declines in magnitude. A comparison of FNRC of Er1 with those of water, OC, and recently developed glass systems-TB, TZ, and TVM60 [23][24][25] is presented in Figure 11b. It is evident that Er1 is a better fast neutron absorber compared to these materials except TVM60.…”

Effect of frequency on the classical and relaxor ferroelectric behavior of substituted titanate Ba0.7Er0.16Ca0.05Ti0.91Sn0.09O3

“…13,14 Additionally, Ahmadu et al observed that Ba 0.88 Ca 0.12 Ti 0.975 Sn 0.025 O 3 contains a tetragonal phase (BCST). 15 They saw that the Ca ions had totally relocated from their initial locations, changing the samples' lattice characteristics in the process. Near the paraelectric-ferroelectric phase transition, Sn substitution led to a decrease in the transition temperature and an increase in the dielectric constant.…”

Sintering Temperature Driven Structural, Dielectric, Ferroelectric, and Piezoelectric Properties of 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 Lead-Free Composites

“…The BaTiO 3 -based ceramics such as (Ba,Ca)(Zr,Ti)O 3 (2,3), (Ba,Ca)(Sn,Ti)O 3 (4,5) and (Ba,Ca)(Hf,Ti)O 3 (6,7) have been widely studied due to their excellent dielectric, ferroelectric and piezoelectric properties for a wide range of applications in electro-optic devices, actuators, infrared detectors, tunable devices, lead-free piezoelectric transducers, multi-layer ceramic capacitors, memory and affordable clean energy storage devices (8)(9)(10)(11). The substitution of Ba 2+ by Ca 2+ lowers the rhombohedral-orthorhombic (T R-O ) and orthorhombic-tetragonal (T O-T ) phase transition temperatures, but causes a small effect on the Curie temperature (T C ) of BaTiO 3 system.…”
