Ceramic-to-Metal Sealing Technology

X-ray tube components operate under demanding combinations of high voltage, vacuum, thermal cycling, and electrical insulation requirements.

TecCera uses high-temperature molybdenum-manganese metallization to prepare alumina ceramic surfaces for subsequent metal plating and brazing.

Typical processes include:

  • Alumina ceramic forming and machining
  • High-temperature Mo-Mn metallization
  • Nickel, copper, or gold plating
  • Precision metal component machining
  • Vacuum brazing
  • Ceramic-to-metal sealing
  • Dimensional and sealing inspection

This manufacturing route enables reliable integration between ceramic insulators and metal structures used in X-ray tube assemblies.

High-purity alumina provides strong dielectric properties, making it suitable for high-voltage insulation structures inside X-ray tubes.

Thermal Stability

Alumina ceramics maintain stable mechanical and electrical properties under elevated temperatures and repeated thermal cycles.

Ceramic-to-Metal Compatibility

Mo-Mn metallization and controlled brazing processes help create reliable interfaces between alumina ceramics and compatible metal components.
