(La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3: A new titano-manganate with a high dielectric constant and antiferromagnetic interactions
(2004)
A new perovskite-based titano-manganate, (La0.4Ba0.4Ca0.2)(Mn0.4Ti0.6)O3, has been prepared by the ceramic route at 1100°C. This oxide was found to possess the cubic perovskite structure with ‘a’=3.9477(23) Å (space group ...
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 (0≤x≤1): synthesis, structure and dielectric properties
(2002)
Oxides belonging to the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were synthesized by the solid state reaction route. Sintering temperatures of 1300°C led to oxides with disordered (cubic) perovskite structure. However, ...
Complex rare-earth titanates with the perovskite structure: Rietveld studies and dielectric properties
(2004)
Several new compositions of the type (Ln2/5Ba2/5Ca1/5)(Cd2/5Ti3/5)O3 and (Ln1/3Ba1/3Ca1/3)(Cd1/3Ti2/3)O3 (Ln = La, Nd, Sm, Gd, Dy) pertaining to the perovskite structure have been investigated. We have also tried to ...
Polymeric citrate precursor route to the synthesis of nano-sized barium lead titanates
(2003)
Monophasic oxides of the formula, Ba1−xPbxTiO3 (0≤x≤1.0) were obtained at temperatures close to 500 °C from polymeric precursors formed using citric acid and ethylene glycol. These oxides were found to be tetragonal for ...
