High Thermal Conductivity Ceramics
Ceramics for High-Temperature Applications
Elcon specializes in the manufacturing of high thermal conductivity ceramic components to help improve the reliability of high-temperature applications, such as photonics, missile guidance, and medical devices. Ceramics with high thermal conductivity offer a heat-management solution for applications where both high thermal transfer and electrical isolation are required, as well as for applications that need to withstand extreme temperatures while remaining chemically inert and dimensionally stable at temperatures greater than 1000°C. High thermal conductivity ceramics effectively transfer and absorb heat from their environment, resulting in lower ceramic surface temperatures and more reliable metal-to-ceramic bonds.
Careful selection of metalizing paints is required during this process since high temperatures will affect the diffusion of metals that can degrade metallization adhesion strength at operating temperatures above 1100°C. In a hermetic braze application, careful selection of the right paint and braze alloy can make the difference between a successful bond and one that will suffer early failure via vacuum leaks or adhesion failure. Elcon manufactures custom paints with a 25-year history of reliably performing at elevated temperatures. Our unique capabilities allow us to turn around high-quality, leak-free parts both quickly and affordably for clients around the world.
