Product Description
Product Overview
0.5mm Black Pyroelectric Free LiNbO3 Wafer 8 Inch 128Y-cut for SAW IDT applications. Lithium Niobate (LiNbO3) is a versatile ferroelectric material with excellent electro-optic, nonlinear, and piezoelectric properties.
Technical Advantages
Black reduced lithium niobate wafers feature enhanced charge neutralization capabilities and significantly reduced pyroelectric effects while maintaining standard piezoelectric performance. This makes them ideal for high-frequency surface acoustic wave devices.

Frequently Asked Questions
What are the products you mainly work on?
We specialize in piezo wafers and were the first to work with Single Crystal Quartz in China about 30 years ago. We now produce LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials. We are particularly known for quartz blanks with superior angle precision in AT, SC, and IT cuts.
Can you accept product customization?
Yes, we offer full customization and can fabricate according to your specifications. Our experienced team can provide technical recommendations if needed. We also maintain standard wafers in stock for immediate delivery.
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.
How can you guarantee we get what we want safely?
We use specialized packaging with buffer sponge and fragile labeling. Please follow our acceptance check procedure: inspect outer carton condition, photograph before opening, open vacuum package in clean room only, and immediately document any damage without removing products from packaging.
Acceptance Check Procedure
- Handle with care and check outer carton condition upon receipt
- Photograph packaging before opening
- Open vacuum package only in clean room environment
- If damage is found, photograph/video immediately without removing products from packaging
