Synthesis and dielectric properties of magnesium niobate -magnesium tantalate solid solutions
Monophasic Oxides of the type MgNb2−xTaxO6 (0 ≤ x ≤ 2) have been synthesized by solid-state reactions using Mg(NO3)2·6H2O as the source of Mg. The oxides crystallize in the orthorhombic columbite structure till X = 1.75 ...
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9 (0≤x≤1): synthesis, structure and dielectric properties
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, ...
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9: synthesis, structural and dielectric studies
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 ...
New double perovskites having low dielectric loss:LaBaZnTaO6, LaSrZnNbO6, and Ba2Zn0.5Ti0.5TaO6
Oxides of the type LaBaZnTaO6 and LaSrZnNbO6 have been synthesized by the solid-state method at 1100°C. Ba2Zn0.5Ti0.5TaO6 was synthesized by the molten salt method (using NaCl–KCl as flux), the solid-state method yielding ...
