Ceramic Metallization & Metal Brazing Solution
At グレート・セラミック, 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 brazingそして 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.
