|Title:||Enhanced Dielectric Properties of Ba3ZnTa2−xNbxO9 in Microwave Region Using Tungstic Acid|
|Publisher:||Taylor & Francis|
|Abstract:||Dielectric resonators belonging to the families of complex perovskite Ba3ZnTa2−xNbxO9 were synthesized by a solid-state reaction route. Calcination at 1250°C leads to oxides with ordered (hexagonal) perovskite structure over the range (0.25 ≤ x ≤ 1.75). However, ordering refraction intensity of PXRD patterns increased on sintering at 1340°C with tungstic acid, as a sintering aid. Sintering has lead to >90% density. In microwave range, Ba3ZnTa0.5Nb1.5O9 shows much higher permittivity (35) and quality factor (43,120 GHz).|
