- Abstract
- Low temperature sintered dielectric ceramics have always attracted much attention in capacitor applications due to their low processing cost and high dielectric properties. Usually, to fabricate low temperature sintered dielectric ceramics, low temperature sintering aids were introduced in the sintering process. This process reduced the sintering temperature by more than 200 degrees C from the conventional sintering temperature range. In this study, CuO was selected as the sintering aid to reduce the sintering temperature and enhance the dielectric properties, and (Ba, Sr)TiO3 ceramics were selected as large capacitor applications. As (Ba, Sr)TiO3 ceramics have highly stable dielectric frequency dispersion properties and a low loss tangent, these materials are suitable for large capacitor-based applications. In particular, well fabricated (Ba, Sr)TiO3 ceramics were intensively investigated for microwave and capacitors applications.
