Quartz Products

In the face of increasing difficulties in supplying quartz crystals for strategic applications such as space, defense and medical, CRYSTALINNOV 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, other orientation on request, …)

Blanks or wafers

• Cuts (AT, SC, Z, X…)
• Lapped, single side or double side polished
• 5 mm to 100 mm

Customized products

• Very high-quality quartz
• Quality criteria according to IEC 60758 standard

As one of the rare European players mastering multiple crystal growth technologies (Czochralski, Hydrothermal, µPD), we ensure traceable, defect-free crystals designed for strategic applications where performance is critical.

Thanks to hydrothermal synthesis, we master the material from seed to final wafer, offering exceptional purity, controlled orientations, and reproducibility.
Our crystals are optimized for ultra-stable oscillators, SAW resonators, inertial navigation, and radiation-resistant devices.
