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.

The properties of the most popular used material Alumina Al2O3 Alumina (Al2O3) is a hard, chemically resistant material and has the ability to withstand very high temperatures in aggressive environments. Innovacera offers Alumina with various purity levels, including 99.8% and 99.0%. The level of purity, grain size, and density required is dependent on the rigors of the application and the component configuration.| Item | Test Condition | Unit&Symbol | 95% Al2O3 | 99% Al2O3 | 99.7% Al2O3 |
