Abstract: | The ceramic material Bi5TiNbWO15 (BTNW) was obtained and is characterized by a layered, Aurivillus type structure (MBLPO—mixed bismuth oxide layered perovskites) with m = 1.5. In order to optimize the production, BTNW was synthesized by two methods: synthesis of a mixture of simple oxides
Bi2O3, Nb2O5, WO3, TiO2 and synthesis of a mixture of appropriate, layered Aurivillus type structures Bi2WO6 (m = 1) and Bi3TiNbO9 (m = 2). Synthesized solid solutions were consolidated with a conventional method. The crystal structure of Bi2WO6 and Bi3TiNbO9 Bi5TiNbWO15 was examined at room temperature with an X-ray diffraction method. Microstructure and chemical composition were analyzed.
The authors analyzed the temperature—permittivity ɛ relationship for the ceramic with m = 1,5, which was obtained with two methods, as well as for m = 1 and m = 2. |
