The ceramic material Bi 5 TiNbWO 15 (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 Bi 2 O 3 , Nb 2 O 5 , WO 3 , TiO 2 and synthesis of a mixture of appropriate, layered Aurivillus type structures Bi 2 WO 6 (m=1) and Bi 3 TiNbO 9 (m=2). Synthesized solid solutions were consolidated with a conventional method. The crystal structure of Bi 2 WO 6 and Bi 3 TiNbO 9 Bi 5 TiNbWO 15 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.
