Product Description
Product Overview
Piezoelectric Langasite (LGS) wafers are advanced crystal substrates designed for high-performance filters operating with both bulk acoustic waves (BAW) and surface acoustic waves (SAW). LGS crystal is a multifunctional material that combines electro-optical properties with piezoelectric performance, making it ideal for precision electronic applications.

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 include LiNbO₃, LiTaO₃, Quartz glass, LGS, and CTGS. We export millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer complete customization and can fabricate according to your specifications. Our experienced team can provide technical recommendations if you're unsure about your requirements. We also maintain standard wafer inventory for immediate availability.
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 minimize shipping costs while ensuring product safety. We can also handle freight arrangements using our established relationships with international carriers.
How can you guarantee we get what we want safely?
We package fragile wafers with multiple protective layers in cartons filled with buffer sponge. Please follow our acceptance check procedure: inspect outer carton condition, photograph packaging before removal, open vacuum packages only in clean rooms, and immediately document any damage without removing products from packaging.
Acceptance Check Procedure
- Handle products with care and check outer carton condition upon receipt
- Photograph packaging alignment before removing contents
- Open vacuum packaging only in clean room environments
- Document any shipping damage immediately with photos/video
- Do not remove damaged products from packaging
- Contact us immediately for resolution of any issues
