Product Description
Ferroelectric Lithium Niobate (LN) wafers are advanced materials engineered for Surface Acoustic Wave (SAW) devices and optical waveguides. These wafers leverage LN's exceptional electro-optic, nonlinear, and piezoelectric properties to deliver superior performance in telecommunications and optical applications.
Key Applications
Lithium Niobate crystals are essential components in mobile phones, piezoelectric sensors, optical modulators, and various linear and non-linear optical systems. The primary application is in SAW devices such as filters and duplexers that prevent noise and interference in voice and data communication systems.

Frequently Asked Questions
What are the products you mainly work on?
We are piezoelectric wafer specialists with over 30 years of experience. We were the first to work with Single Crystal Quartz in China and have expanded to LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials. We are the ultimate choice for piezo quartz suppliers, exporting millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Can you accept product customization?
Yes, we can fabricate wafers according to your specific requirements. Our experienced team can provide technical suggestions if you're unsure about your specifications. We also maintain standard wafer inventory for immediate delivery.
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier agent (DHL, FedEx, UPS, etc.) via your account. We optimize packaging to reduce shipping costs while ensuring product safety. We also offer our own shipping services with discounted international courier rates.
How can you guarantee we get what we want safely?
We use adequate packaging with buffer sponge and fragile labeling to protect these delicate wafers during transit. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before removal, open vacuum packages in clean rooms only, and immediately document any damage without removing products from packaging.
Acceptance Check Procedure
