Product Description
Lithium Tantalate (LiTaO3) Wafer Overview
Lithium Tantalate (LiTaO3) optical crystal is a transparent material with exceptional piezoelectric, electro-optic, acousto-optic, and nonlinear optical properties. This makes it an ideal choice for acoustic transmission media and high-frequency transducers in telecommunications and mobile phone applications.
Key Applications
- Surface acoustic wave filters and resonators
- Q-switches and optical modulators
- Acousto-optic switches and laser frequency doubling
- Optical parametric oscillators and optical storage systems
- High-temperature and high-frequency ultrasonic detectors
- Infrared detectors and optical pickup devices

Frequently Asked Questions
What are your main products?
We specialize in piezo wafers and were the first to work with Single Crystal Quartz in China approximately 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 in AT, SC, and IT cuts.
Do you accept product customization?
Yes, we can fabricate according to your specifications. Our extensive experience with piezo wafers allows us to provide valuable suggestions if you're uncertain about your selection. We also maintain standard wafers in stock for immediate availability.
Can you ship via our courier agent?
Yes, we recommend using courier services you're familiar with (DHL, FedEx, UPS, etc.). We can ship using your account and will package products securely in appropriate sizes to optimize shipping costs. We also offer freight management services with discounted international courier rates.
How do you ensure product safety during shipping?
We package wafers adequately in cartons with buffer sponge to prevent damage. Please follow the acceptance check procedure outlined below. If damage occurs during transit and you've followed the checking steps, we'll provide replenishment or refund.
Can we visit your factory?
Absolutely. Factory inspections are important for large quantity purchases and long-term partnerships. We've hosted numerous global clients and also offer videoconferencing options during the Covid-19 pandemic.
Acceptance Check Procedure
- Products are fragile and adequately packed with fragile labels
- After receipt, check outer carton condition and photograph before opening
- Open vacuum packaging in clean room only when ready for application
- If damage is found, photograph/video immediately without removing from packaging and contact us
