03 / APPLICATIONS
The right cut and finish can influence acoustic coupling, optical interaction and process yield. Choose the application first, then specify the wafer.
Bulk or thin-wafer routes for optical waveguides, modulators, frequency conversion and nonlinear optics.
Discuss wavelength & cut ↗
Piezoelectric substrates for filters, resonators and front-end acoustic components in communication devices.
Discuss acoustic design ↗Stable crystal platforms for medium and low-frequency filters, high-power transducers and sensing systems.
Discuss device format ↗SELECTION NOTE
Tell us the frequency, aperture, electrode process, optical wavelength, wafer diameter and expected quantity. We will help separate must-have parameters from negotiable ones.
Prepare an enquiry ↗04 / WHY XINKEHUI
Our value is not only the crystal. It is the clarity between your requirement, the lot and the delivery date.
Review cut, dopant, thickness, polish and edge details against the actual process instead of a generic catalogue line.
Quantity, inspection scope and packaging are discussed early so the promised schedule is realistic and traceable.
Geometry, roughness, orientation and visible-defect requirements stay explicit from RFQ through lot communication.
Shanghai-based support across semiconductor substrates, optical crystals and engineered material components.
Specifications are reference values from the supplied product sheet. Written quotation and lot inspection criteria take precedence.

Shanghai · China06 / ABOUT XINKEHUI
Shanghai Xinkehui New Materials Co., Ltd. focuses on the production, processing and sales of semiconductor and crystal materials.
Our wider portfolio includes silicon and SiC wafers, sapphire substrates, CVD synthetic diamond, YAG single crystals, ZnSe windows and sapphire components. For lithium niobate and lithium tantalate projects, we keep the conversation close to the specification: what the device needs, what the lot can document and when the material can arrive.
07 / FAQ
Technical and commercial questions we hear most often about LiNbO3 and LiTaO3 wafers.
Lithium niobate is widely selected for nonlinear optical, electro-optic and piezoelectric devices, while lithium tantalate is valued for stable piezoelectric, pyroelectric and acoustic performance in resonators, filters and SAW devices.
The supplied product sheet lists 3, 4, 6 and 8 inch lithium niobate wafers and 3, 4 and 6 inch lithium tantalate wafers. Availability and custom sizes require confirmation.
Yes. Single or double doped lithium niobate options including MgO and Zn are listed for review. Confirm dopant concentration, crystal orientation and acceptance criteria in the RFQ.
Common LiNbO3 options include X, Z, Y, 41°, 64° and 128° Y-cut. LiTaO3 options include X112°, Y28°, Y36° and Y42°. Custom orientation can be reviewed against your device design.
Single-side polish, double-side polish, lapping and grinding routes are listed. Discuss the polished face, backside texture, roughness, edge geometry and cleaning requirement before quotation.
Reference thicknesses are 0.18, 0.25, 0.35, 0.50 and 1.00 mm for lithium niobate, and 0.25, 0.35, 0.50 and 1.00 mm for lithium tantalate, subject to tolerance and lot confirmation.
Lithium niobate and lithium tantalate are established piezoelectric substrates for surface acoustic wave filters and resonators. Select the cut, propagation direction, diameter, thickness and electrode process together with your design team.
Lithium niobate supports nonlinear optical and electro-optic applications such as waveguides, modulators and frequency conversion. Share wavelength, crystal cut, aperture, surface finish and any thin-film or bulk requirement.
Include diameter, thickness, TTV, bow, warp, LTV, PLTV, edge profile, flat or notch, orientation tolerance and surface roughness. The product sheet gives reference values, while the quotation and inspection method govern the lot.
XINKEHUI supports requirement-led review for custom thickness, orientation, polishing and edge details. Send a drawing or specification table so feasibility, quantity and delivery can be assessed before an offer.
This page does not publish a fixed price or real-time stock promise. Price and lead time depend on material, diameter, doping, cut, finish, quantity and inspection requirements. Request a written quotation and current availability.
Store wafers in clean protective packaging, use powder-free gloves and avoid touching polished faces. Confirm packaging, cleaning and handling instructions for the ordered lot.
08 / CONTACT
Tell us the device, the wafer and the date. We will help turn that into a clear technical enquiry.
