Product Description
High-Quality Single Crystal Quartz Wafer Overview
This 6-inch high-Q single crystal quartz wafer with ST 42.75 orientation is engineered specifically for MEMS (Micro Electro Mechanical Systems) and SAW (Surface Acoustic Wave) applications. Monocrystalline quartz has become indispensable in modern electronics due to its exceptional piezoelectric properties, high mechanical and chemical stability, and superior Q-factor at resonance. Advanced manufacturing techniques now enable production of extremely high-purity synthetic material at competitive costs.
