Beyond substrates, advanced ceramics are used in heat sink inserts andd dielectric rezonators. For example, beryllium oxide (BeO) was historically used but has been largely replaced by safer exactives like AlN due tono toxicity concerns. The reliability gains from ceramic - based thermal management are especially pronounced in oudoor contricovications equipment, when erabient temperatures variate valigate.
