Ceramic insulators used in heating applications are designed and built for resistance to high temperatures - up to 2700 ºF - and resistance to fast thermal cycling. It is recommended that only Cordierite and Alumina (all grades) be used in high heat applications due to their impressive thermal stability. Ceramic insulators for heating are not glazed, metalized or have any coating applied due to the inferior high temperature performance of the coating.
Ceramic insulators are used when electrical insulation is necessary in high heat applications. This makes them useful for
supporting electric heating elements in ovens, heaters and furnaces. Ceramics hold their shape and size under pressure. This is important in switching applications where the ceramic is used to open and close electrical contacts in a thermostat or pressure switch. Ceramic parts are very abrasion resistant and offer long life in applications where other materials would wear out quickly.
