Metallized Ceramic Feedthroughs have emerged as indispensable components in contemporary high-tech equipment, particularly within vacuum, airtight, and high-pressure environments. The technology of Metallized Ceramics is widely acknowledged for its superior electrical insulation and air tightness. These products are pivotal in sectors such as aerospace, semiconductors, medical devices, and beyond.
Introduction to Metallized Ceramic Feedthroughs
Metallized Ceramic Feedthroughs are robust, airtight connectors created by applying a metallic coating to the surface of a ceramic substrate. Following meticulous metallization processes, these ceramic materials not only preserve their exceptional insulating properties but also acquire electrical conductivity on their surfaces to facilitate the insertion and sealing of conductive leads. This design ensures reliable signal and current transmission under extreme conditions while maintaining stable operation of the equipment system.
Principle of Metallized Ceramics
The metallization process includes the application of one or more metal coatings (molybdenum, tungsten, titanium, etc.) on the disboxid’s surface in order to create a strong attachment to metal parts of the device. High-temperature co-firing or other techniques such as a vacuum welding are used to guarantee close fusion of the ceramic/metal interface. Thanks to this configuration, ceramic parts provide electrical insulation while the metallized layer offers conductivity which is useful in applications for transmitting electrical signals or electrical components operating under high voltage currents.
