Product Description
Ferroelectric LiNbO3 Wafer Overview
Lithium Niobate (LN) is a ferroelectric material with exceptional electro-optic, nonlinear, and piezoelectric properties. These crystals are essential for optical waveguides, mobile phones, piezoelectric sensors, optical modulators, and various linear and nonlinear optical applications.
Primary Applications
The largest application of Lithium Niobate is in Surface Acoustic Wave (SAW) devices used in telecommunications equipment. SAW filters and duplexers are critical components that prevent noise and interference during voice and data communications. LN crystals also serve important roles in optical applications requiring precise wave guidance.

Frequently Asked Questions
Product Specialization
What are the products you mainly work on?
We are piezoelectric wafer specialists with over 30 years of experience, starting as China's first single crystal quartz manufacturer. Our expertise extends to LiNbO3, LiTaO3, quartz glass, LGS, and CTGS materials. We are particularly recognized for our precision in AT, SC, and IT cut quartz blanks, exporting millions annually with superior angle accuracy.
Customization Capabilities
Can you accept product customization?
Yes, we offer complete customization services and can fabricate wafers according to your specifications. Our extensive experience allows us to provide valuable technical guidance if you're uncertain about material selection. We also maintain standard wafer inventory for immediate availability.
Shipping and Logistics
Can you deliver the goods via our courier agent?
Yes, we can ship using your preferred courier service (DHL, FedEx, UPS, etc.) via your account. We optimize packaging to minimize shipping costs while ensuring product safety. Alternatively, we can handle freight arrangements using our established relationships with international carriers.
Quality Assurance
How can you guarantee we get what we want safely?
We employ comprehensive protective packaging with vacuum sealing and buffer materials to prevent damage during transit. However, should any issues occur, we provide replacement or refund options when customers follow our documented acceptance checking procedures.
Factory Access
Can we visit your factory?
Factory inspections are welcome, particularly for large quantity purchases and long-term partnerships. We have hosted numerous international clients and, during COVID-19 restrictions, have successfully conducted virtual factory tours via videoconferencing.
Acceptance Check Procedures
Step-by-step acceptance check procedure for LiNbO3 wafer inspection
  • Products are fragile and adequately packed with "Fragile" labeling
  • Use premium domestic and international express services for quality transportation
  • Handle with care upon receipt and inspect outer carton condition
  • Document packaging alignment with photographs before removing contents
  • Open vacuum packaging only in clean room environments during application
  • If damage is detected during shipping, photograph/video immediately without removing products from packaging
  • Contact us immediately for resolution of any transit-related issues
