Product Description
Product Overview
4-inch single-side polished Lithium Tantalate (LiTaO3) wafers in 36°Y and 42°Y orientations, specifically engineered for surface acoustic wave (SAW) device manufacturing in the electronics industry.
Key Features & Applications
Lithium Tantalate crystals offer superior piezoelectric properties essential for SAW devices. With an electromechanical coupling ratio of 1:1.5, they provide significantly higher surface-to-surface connection efficiency compared to quartz.
Our reduced LiTaO3 wafers are specially treated to neutralize pyro-electric charges, preventing interdigital electrode burn during high-temperature processing cycles common in SAW device production.

Frequently Asked Questions
What are your main product specialties?
We are piezoelectric wafer specialists with 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 export millions of quartz blanks annually with superior angle precision for AT, SC, and IT cuts.
Do you accept product customization?
Yes, we can fabricate according to your specifications. Our experienced team can provide technical recommendations if needed. We also maintain standard wafer inventory for immediate availability.
Can you ship via our preferred courier?
Yes, we can ship using your preferred courier account (DHL, FedEx, UPS, etc.). We optimize packaging to minimize shipping costs while ensuring product safety. We also offer our own shipping services with discounted rates.
How do you ensure product delivery safety?
We use specialized packaging with buffer materials and fragile labeling. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before opening, and only open vacuum packaging in clean room environments. Contact us immediately if damage is detected.
Can we visit your factory?
Factory inspections are welcome for large orders and long-term partnerships. We also offer video conferencing for remote discussions and factory tours.
Acceptance Check Procedure
- Handle products with care upon receipt
- Check outer carton condition and photograph before opening
- Open vacuum packaging only in clean room environments
- If damage is found, do not remove from packaging and contact us immediately
All wafers are packaged with specialized materials and labeled as fragile to ensure safe transportation. Follow acceptance check procedures carefully to maintain product integrity.
