More info

Quartz (SiO2) Single Crystal Wafer is a high-purity, single-crystal quartz wafer with precise crystallographic orientation. It offers excellent mechanical stability, low dielectric loss, and well-defined piezoelectric properties, making it essential for frequency control, resonators, and high-precision optical applications. Available in X-Cut, Y-Cut, AT-Cut, and ST-Cut, each cut provides distinct advantages in temperature stability and frequency response. Advanced synthetic quartz production ensures minimal impurities and high reliability. Additionally, we provide Optical Grade Quartz Wafers with ultra-high purity, exceptional transparency, and high laser damage resistance for demanding optical applications. Heeger Materials provides high-quality Quartz Single Crystal Wafers to meet the needs of research and industrial applications.
