Dielectric ceramics are materials that are poor conductors of electricity but can store electrical energy. They are commonly used in capacitors, which are essential components in electronic devices. These ceramics have high dielectric constants, allowing them to effectively store and release electrical energy. These materials are typically made from compounds like barium titanate or lead zirconate titanate. Their unique properties make them valuable in various applications, including telecommunications, sensors, and insulators. The ability to withstand high temperatures and voltages further enhances their utility in modern technology.
