Metalized Ceramics for Electrical Components

Metalized Ceramic

INNOVACERA supplies custom refractory metalized alumina ceramics for use in power grid tubes, x-ray tubes, vacuum interrupters, and similar applications where ceramic-to-metal seal joints of exceptional strength and hermeticity are required.

Ceramic material:

Deposition methods:

  • Screen printing
  • Pad printing
  • Brush coating

A coating of molybdenum-based paint followed by nickel plating can provide an interface where the ceramic/metal component can be formed by brazing, providing a sealed joint. After sintering, a layer of molybdenum-manganese alloy with a thickness of 10–30 μm was deposited. The metallization sintering process is carefully controlled to achieve a balanced mixture of molybdenum particles surrounded by a glass matrix to insure high bond strength between the metallization layer and the ceramic matrix.
