Morgan Advanced Ceramics Deranox™ 970 Alumina
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: High-quality alumina ceramic of 97.0% Al2O3 content. This material is an excellent electrical insulator that can be metallized to facilitate high-temperature brazing of assemblies.

Prime features

  • Readily accepts metallizing with moly-manganese
  • Very high volume resistivity
  • Low loss, constant high dielectric
  • High density, non-porous and vacuum tight
  • Resists abrasive wear and chemical attack.
Typical applications:
Metallized ceramic components used in high-integrity applications, including:
  • High-vacuum systems
  • Laser equipment (gas, solid-state and waveguide)
  • X-ray tubes and electron microscopes
  • Microwave windows
  • Insulators in medical and scientific equipment.
