Ceramic-To-Metal Sealed Electrodes

Ceramic-to-metal sealed electrodes are components used in various electrical and electronic devices, particularly in applications where a hermetic seal is required to prevent contamination or leakage of gases or liquids. These electrodes are designed to provide a reliable electrical connection between the internal electrical components of a device and the external environment, while also maintaining the integrity of the enclosure.
Common materials used for the ceramic insulator include alumina (aluminum oxide) and beryllia (beryllium oxide), while the metal conductor is often made of materials such as nickel, Kovar (an alloy of iron, nickel, and cobalt), or stainless steel, depending on the specific requirements of the application.
