Electroceramics can be defined as ceramic materials which are able to perform an electronic function for a particular application. Most ceramics, and indeed electroceramics, are electrically insulating in nature; they resist the flow of current and are able to separate charge as a result. This rather wide umbrella-term includes materials for a wide range of applications, of varying complexity, from relatively simple insulating materials, to complex ferroelectrics. The materials for such applications are usually prepared from specifically formulated compositions, and processed under strictly controlled conditions.
