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, ... -
Ba3ZnTa2−xNbxO9 and Ba3MgTa2−xNbxO9: synthesis, structural and dielectric studies
(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 ... -

Behaviour of equipment mounted over a torsionally coupled structure with sliding support
(2000)Behaviour of a light equipment system mounted over a torsionally coupled and sliding primary system, is studied under bidirectional ground excitation. A fictitious spring model is considered in the analysis to deal with ... -
