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.
Bars
Bars are from pure Z-zone, with or without seed, Y0, or pre-oriented for a specified cut (AT, SC…)
Blanks or wafers
- Cuts (AT, SC, Z, X…)
- Lapped, single side or double side polished
- 5 mm to 150 mm

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…)
