Product Description
Product Overview

6-inch diameter, 0.5mm thickness Lithium Niobate (LiNbO3) wafer with 64Y/128Y crystal orientation, single side polished specifically for Surface Acoustic Wave (SAW) device applications.

Material Properties

Lithium Niobate offers excellent nonlinear optical properties, making it ideal for optical waveguide applications and SAW device manufacturing. The material supports medium to low frequency SAW filters, high-power high-temperature ultrasonic transducers, and various doping configurations including Mg:LN, Nd:Mg:LN, and Fe:LN.

Lithium Tantalate provides superior piezoelectric, ferroelectric, acousto-optic and electro-optic characteristics, widely used in resonators, filters, transducers, and high-frequency surface acoustic wave devices.

Frequently Asked Questions
What are your main product specialties?
We specialize in piezoelectric wafers and were China's first manufacturer of single crystal quartz over 30 years ago. Our expertise extends to LiNbO3, LiTaO3, quartz glass, LGS, and CTGS materials. We export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Do you accept product customization?
Yes, we offer complete customization services and can fabricate wafers according to your specifications. Our experienced team can provide technical recommendations if you're uncertain about material selection. We also maintain standard wafer inventory for immediate delivery.
Can you ship using our preferred courier service?
We can ship via your preferred courier account (DHL, FedEx, UPS) and will package products in optimal sizes to minimize shipping costs. Alternatively, we can arrange shipping using our established relationships with international carriers.
How do you ensure product safety during shipping?
We package fragile wafers with adequate protection in cartons filled with buffer sponge. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before opening, open vacuum packages only in clean rooms, and immediately document any damage without removing products from packaging. We provide replacements or refunds for damaged goods when proper procedures are followed.
Acceptance Check Procedure
Step-by-step acceptance check procedure for Lithium Niobate wafer inspection
  • Products are fragile and adequately packed with "fragile" labeling
  • Upon receipt, carefully inspect outer carton condition and photograph packaging alignment
  • Open vacuum packaging only in clean room environments
  • If damage is found, photograph/video immediately without removing from packaging and contact us
