“…A(B B )O 3 , (A A )BO 3 and (A A )(B B )O 3 are known [9][10][11][12]. The effects of the substitution of a number of cations having different valence, for example Hf 4+ Mn 4+ , Tb 3+ Fe 3+ Er 3+ Sb 3+ La 3+ , in the appropriate sublattices of barium titanate are extensively investigated [13][14][15][16][17][18][19]. However, there is little information about the influence of vanadium ions presence in the barium titanate lattice on its microstructure and ferroelectric properties.…”

The study shows the advisability of using a mechanochemical synthesis method, based on a high-energy planetary ball milling, to a modification of barium titanate by a vanadium doping. This method improves useful properties of BaTi 0.95 V 0.05 O 3 as a capacitor material. It has a high value of electric permittivity ε in the wide range of temperature and low dielectric losses ε as well as a low electrical conductivity.

“…BaTiO 3 is one of the most useful compounds of the perovskite family because of its high dielectric constant and ferroelectric properties. BaTiO 3 is most widely used in making multilayer ceramic capacitors (MLCC), thermistors and piezoelectric sensors [1][2][3][4][5][6]. It has been shown that finer particles i.e.…”

Dissolution of barium ion from aqueous suspensions of commercial nano-sized barium titanate powders (BaTiO 3 ) has been studied at various pH values, solids loading, different time intervals and different electrolyte concentrations. Zeta potential measurements at various pH values and Fourier transform infrared spectroscopy study were also carried out to know the surface behaviour. Dissolution of Ba 2þ depends on the suspension pH and stirring time period. The iso-electric points were found at 3.4 and 12.2 for as-received BaTiO 3 powder and 2.3 for the leached BaTiO 3 . The Ba 2þ -leached BaTiO 3 suspension retards further leaching of Ba 2þ ions at different pH values, which favours the achievement of stable suspension.

“…La 3+ (1.15 Å ) is exclusively incorporated at the Ba 2+ (1.35 Å ) site, as its size is incompatible with that of Ti 4+ (0.68 Å ), La 3+ produces n-type semiconductors. Addition of lanthanum as a donor dopant at a relatively low concentration (<0.5 at%) leads to room temperature semiconducting ceramics with positive coefficient of resistivity (PTCR) properties, whereas higher dopant concentration leads to insulating materials [2,3].…”
