Direct bonding of sapphire and alumina without adhesives.

- High bonding strength
- Excellent heat resistance to control thermal deformation
(for example, windows made from A479SS, Kyocera Material Code, can be used up to about 1,500 degree C)
- Superior chemical resistance
- No adhesives results in few impurities and particles


  • High Heat Resistance
  • Chemical Resistance
  • Light Transmittance
