Collaborative European Technology Platform for innovation

Quartz

In the face of increasing difficulties in supplying quartz crystals for strategic applications such as space, defense and medical, Cristal Innov has resumed European production of very high-quality quartz and wafers.

QUARTZ Bars are from pure Z-zone Cristal Innov

Bars

Bars are from pure Z-zone, with or without seed, Y0, or pre-oriented for a specified cut (AT, SC…)

QUARTZ BLANKS OR WAFERS Cristal Innov

Blanks or wafers

  • Cuts (AT, SC, Z, X…)
  • Lapped, single side or double side polished
  • 5 mm to 150 mm
QUARTZ RESONATORS Cristal Innov

Hydrothermal synthesis

Cristal Innov has specialized in the crystallization of very high-quality quartz, by mastering the material, the specific cuts, and their characterization.

Both very slow growth rates – inhibiting the formation of defects –, and reproducibility make it possible to produce high-performance crystals for piezoelectric applications:

  • ultra-stable, low-noise resonators/oscillators
  • SAW sensors, inertial navigation system (accelerometers, gyroscopes…)
