Product Description
8" 0.5mm Black Lithium Niobate Wafer for SAW Applications
This 8-inch 0.5mm 128Y-cut Black Lithium Niobate Wafer is engineered for Surface Acoustic Wave (SAW) device applications and Interdigital Transducer (IDT) use. Featuring exceptional surface quality with Ra roughness of 1nm, this wafer delivers superior performance in high-frequency applications.
The reduction technology used in production creates Black Lithium Niobate (LiNbO3) with enhanced electrical charge neutralization capabilities, even under instantaneous electrical potential. The pyroelectric effect is nearly eliminated while maintaining identical piezoelectric properties to standard wafers, making black reduced lithium niobate wafers ideal for advanced SAW devices.

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 LiNbO3, LiTaO3, Quartz glass, LGS, and CTGS materials. We are the ultimate choice for piezo quartz suppliers, exporting millions of quartz blanks annually with superior angle precision in AT, SC, and IT cuts.
Can you accept product customization?
Yes, we can fabricate according to your specific requirements. Our extensive experience with piezoelectric wafers allows us to provide valuable suggestions if you're uncertain about your specifications. We also maintain standard wafers in stock for immediate delivery.
Can you deliver the goods via our courier agent?
Yes, we recommend using the courier agent you're most familiar with (DHL, FedEx, UPS, etc.). We can ship using your account and will package products safely in acceptable sizes to minimize shipping costs. We also offer competitive freight rates through our partnerships with international courier companies.
How can you guarantee we get what we want safely?
We understand the fragility and value of wafer products. We employ adequate packaging with buffer sponge in proper cartons and label packages as fragile. However, accidents can occur, so please follow the acceptance check procedure below. If damage occurs during courier and you follow the checking steps, we will provide replenishment or refund.
Acceptance Check Procedure
- Handle products with care upon receipt and inspect the outer carton condition
- Carefully open the outer carton and check packaging box alignment
- Take photographs before removing products from packaging
- Open vacuum packages only in clean room environments when ready for application
- If damage is found during courier, immediately photograph or video record without removing damaged products from packaging boxes
- Contact us immediately for resolution
