Metalized Alumina Ceramics parts
ZG supplies custom Metalized Alumina Ceramics designed for high vacuum, high voltage, and high pressure applications. These metallized ceramics are essential components for power grid tubes, vacuum interrupters, RF windows, metallized rings, and various insulators and sensors.
Material Properties
Alumina is among the most widely used engineering ceramic materials, providing exceptional hardness, wear resistance, and superior electrical insulation properties. Our high-purity alumina ceramics (94-96% Al₂O₃) serve as the base material, with alternative ceramic materials available upon request.
Manufacturing Process
Our standard metalized alumina ceramics utilize molybdenum-based paints followed by nickel plating. A specialized coating containing molybdenum and manganese particles mixed with glass additives and volatile carriers is applied to the ceramic surface through hand-painting, spraying, or robotic application methods.
After air drying, the coating undergoes firing in a wet hydrogen environment at 1450°-1600°C, resulting in a "glassy" metallic coating measuring 300-500 micro-inches (7.6-12.7 microns) thick. This process ensures exceptional bond strength between the metallized layer and ceramic base.
The fired coating is then plated with a 0.001-0.003 inch (25.4-76.2 microns) nickel layer. The nickel plating undergoes sinter-firing at 850-950°C in a dry hydrogen atmosphere, creating a finished metallic surface ready for brazing with standard braze filler metals.
Advantages of Ceramics
  • Low dielectric loss with optimal dielectric constant
  • High thermal conductivity for efficient heat dissipation
  • Compatible thermal expansion coefficients between ceramics and metals
  • Exceptional bonding strength between metal layer and ceramic substrate
  • High operating temperature capability, withstanding extreme temperature cycles and normal operation at 500-600°C
  • Superior electrical insulation properties with high breakdown voltage resistance
