Ceramic Metallization & Metal Brazing Solution
At Grande céramique, we provide professional ceramic surface metallization and brazing services for demanding industries such as aerospace, power electronics, vacuum systems, medical devices, and semiconductor manufacturing.
Combining deep expertise in technical ceramics, precision brazinget hermetic ceramic-to-metal seal design, we help customers create reliable, high-performance assemblies that perform in extreme environments.
Ceramic metallization is the process of applying a conductive metal layer onto the surface of ceramic components, enabling them to be soldered, brazed, or electrically connected to metals. This process is essential for producing ceramic to metal seals in vacuum systems, high-frequency devices, and electrical insulation assemblies.
At Great Ceramic, we offer multiple metallization options:
Metallized Ceramic Components We Provide

Metallized Ceramic Insulator
Suitable for RF windows, laser systems, and sensor housings

Vacuum Ceramic Component
Tailored to specific mechanical, electrical, or environmental requirements

Metallized Ceramic Tubes
Used in electron tubes, thermocouples, and insulation

Metallized Ceramic Ring
Hermetic feedthroughs for vacuum and power devices
All metallized layers are inspected for adhesion, thickness, continuity, and surface quality. Plated layers are tested for solderability and corrosion resistance.
Once metallized, ceramic parts are brazed to metals like Kovar, titanium, or stainless steel using high-temperature brazing techniques. This creates ceramic-to-metal assemblies with superior gas-tightness and mechanical reliability.
Great Ceramic can provide technical ceramic brazed components to meet the specific requirements of customers. Many of the parts we provide are complex, designed to strict specifications or used in particularly demanding critical applications.
Ceramic Brazing Features
Le produit adopte le matériau Kovar ou le cuivre exempt d'oxygène dont le coefficient de dilatation linéaire est similaire à celui des céramiques, afin de réaliser le scellement céramique-métal par brasage. Il permet de réaliser une connexion étanche à l'air entre les pièces en céramique et les pièces structurelles en métal. Cette structure d'étanchéité céramique-métal présente les caractéristiques suivantes : force d'étanchéité élevée, bonne étanchéité à l'air et grande fiabilité.
Ceramic Brazing & Sealing Applications
Utilisé dans les tubes de commutation à vide pour l'énergie électrique et l'électronique, divers klystrons, tubes à ondes progressives, tubes à micro-ondes, magnétrons, thyratrons, déclencheurs, jauges à vide, dispositifs de vision nocturne à micro-ondes et autres industries connexes d'isolation sous vide. La température d'utilisation générale ne dépasse pas 700°C.
Applications of Metallized Ceramics & Brazed Assemblies
Our metallized ceramics et brazed components are widely used across industries for critical tasks that require hermeticity, electrical insulation, thermal conductivityet mechanical strength.
