2. Ceramic capacitors

Ceramics are inorganic, non-metallic materials that have been processed using a special technology known as ceramic technology: the material is initially in the form of fine powders, micron or submicron in size, which are combined to form an object. It is then subjected to a high-temperature thermal cycle (firing or sintering). The resulting object is called "sintered", and its microstructure, which has evolved during firing, is a compact assembly of grains separated by grain boundaries. The material thus acquires its definitive properties (whether mechanical or electrical). Ceramic capacitor materials are generally oxides with a perovskite-type crystalline...
