This thesis presents the preparation and characterization of dielectric ceramic composites based on barium titanate (BaTiO₃) and Mg2Al4Si5O18 cordierite ceramics, using sodium metasilicate (Na2SiO3) as a binder. The main objective was to evaluate the effectiveness of the room temperature fabrication (RTF) method for producing composites with suitable dielectric and mechanical properties for modern electronic applications, particularly in the microwave frequency range.
The experimental work included the synthesis of cordierite ceramics, preparation of composites with varying binder content, and dielectric and mechanical testing. Results showed that composites with lower binder content achieved higher relative permittivity and lower dielectric losses. Mechanical testing confirmed that sodium metasilicate significantly improves flexural strength compared to lithium molybdate (Na2MoO4).
The findings demonstrate that the Room Temperature Fabrication (RTF) method is a viable approach for producing functional ceramic composites with promising properties, supporting further development of low-temperature processing technologies in electronics.
