Product Details
Metallized Ceramic
Indarren metallizes precision ceramic for electronic equipment, vacuum industry applications. The metallized parts are used in critical assemblies brazed by our team. Our metallization creates a strong and robust bond to many different ceramic bodies and has nearly universal applicability for ceramic to metal brazing.
Our ceramic metallization process uses proprietary thick film molybdenum/manganese and molybdenum/manganese/tungsten paints as the base layer on a ceramic substrate. This unique formulation developed and produced entirely in-house enables a hermetic ceramic to metal bond in a brazed assembly.
To prevent oxidation and to improve wettability after the metallization paint is sintered into the ceramic at high temperature, it is plated using either electroless or electrolytic plating or nickel oxide paint. Metallization and nickel thickness is measured using XRF technology to ensure desired thickness specifications are met.
With more than ten years of industry experience, Indarren has expertise in a variety of application methods and is capable of metallizing on flat, cylindrical, and complex ceramic bodies, from prototyping through production.
