Product Description
Alumina Ceramic Electrical Isolators
Electrical isolators consist of metal sleeves brazed to each end of an insulating ceramic tube. These assemblies provide electrical isolation of system components that operate within a common environment. They can also be used to act as a conduit to introduce gases or liquids into hermetic systems. Vacuum isolators are used to provide an electrical break between the vacuum system and other external components.

Metal layers are applied to ceramic components through Mo/Mn metallization and subsequent plating or active brazing techniques. The fusion of ceramic and metal components occurs through the controlled melting and solidification of filler metals (solders), tailored to specific applications and operating temperatures.
Advantages of Ceramic-to-Metal Technology:
The incorporation of advanced ceramic materials offers an array of benefits including high melting points, exceptional temperature resistance, corrosion and abrasion resistance, as well as unique electrical properties such as radiation, high-frequency, and high-voltage resistance. With the evolving landscape of technology, engineering structures often necessitate the synergistic integration of advanced ceramics and metals to harness the complementary strengths of both materials, ultimately optimizing performance.
Through the innovation of ceramic-to-metal brazing, the performance of welded joints is enhanced, enabling operation in elevated temperatures and hostile environments, thereby expanding the spectrum of application possibilities.
By leveraging the ultimate fusion of ceramics and metals, this breakthrough technology heralds a new era of engineering excellence, poised to drive advancements across diverse industries.
