Morgan Advanced Ceramics Sintox ™ FA Metallizing Mac-A950R-3 Aluminum Oxide Ceramic
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: Alumina ceramic with 95.0% Al2O3 content that is specially formulated for accurate grain size. This is feature particularly valuable when a ceramic microstructure is needed to provide a good keying surface for high integrity molybdenum metallizing.

Prime Features:

  • Dense, non-porous and vacuum tight
  • Readily accepts molybdenum metallizing for high temperature brazing of assemblies
  • High volume resistivity
  • Good high temperature characteristics
  • Low coefficient of expansion
  • Resists chemical attack
  • Fire resistant and non-outgassing
Typical Applications:
  • High vacuum equipment and scientific instruments where ceramic components need to be brazed to form high strength connections and complex assemblies
  • Insulators for probes and sensors
  • Transducer components
  • Insulators for vacuum pumps
  • Gun assemblies and connectors for X-ray tubes and electron microscopes
Production Capabilities:
  • Pressed and machined components
  • Metallizing of components
  • High temperature brazing of assemblies
