Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9: synthesis, structural and dielectric studies

Thirumal, M; Murugan, G Senthil; Varma, K B R; Ganguli, A K (2000)

Oxides of the families Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 were obtained by the solid state reaction route at 1573 K and were found to crystallize in the disordered (cubic) perovskite structure. In Ba3ZnTa2−xNbxO9 and ...

Polymeric citrate precursor route to the synthesis of nano-sized barium lead titanates

Arya, P R; Jha, P; Subbanna, G N; Ganguli, A K (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 ...

Dielectric properties of lead zirconium titanates with nanometer size grains synthesized by the citrate precursor route

Jha, P; Arya, P R; Ganguli, A K (2003)

Monophasic oxides of the formula, PbZrxTi1−xO3 (0.0≤x≤0.75) were obtained at temperatures close to 500 °C from polymeric precursors formed using citric acid and ethylene glycol. The oxides were found to be tetragonal for ...

Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 (0≤x≤1): synthesis, structure and dielectric properties

Thirumal, M; Jawahar, I N; Surendiran, K P; Mohanan, P; Ganguli, A K (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, ...
