Product Description
Alkaline-Free Glass Wafers: Your Foundation for Next-Generation Display & Advanced Technologies
For industries demanding high-performance, environmentally friendly glass solutions, our Alkaline-Free Glass Wafers set a new standard. Engineered without alkaline metal oxides (such as Na₂O or K₂O), these wafers eliminate the risk of ionic contamination, making them ideal for semiconductor packaging, MEMS devices, display technologies, and biocompatible applications.
Our alkaline-free glass offers exceptional thermal stability, low thermal expansion, and superior chemical resistance, ensuring minimal deformation and degradation in harsh environments. With excellent optical transparency (visible to near-IR range) and ultra-smooth surface finishes, these wafers enhance precision in lithography, etching, and bonding processes while reducing particle generation.
Available in custom diameters, thicknesses, and surface treatments (e.g., polished, anti-reflective coating), our alkaline-free glass wafers meet stringent industry standards for flatness and purity. Whether for research, prototyping, or high-volume manufacturing, they provide a cost-effective, sustainable alternative to traditional borosilicate or soda-lime glass.
Choose innovation without compromise—opt for our Alkaline-Free Glass Wafers for superior performance and eco-conscious reliability. Contact us today to request a sample or discuss your specifications!

FAQs:
- Q: What are the products you mainly work on?
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
- Q: Can you accept product customization?
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
- Q: Can you deliver the goods via our courier agent?
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
- Q: How can you guarantee we get what we want safely?
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
- Q: Can we visit your factory?
A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
Acceptance Check
- The product is fragile. We have adequately packed it and labeled it fragile. We deliver through excellent domestic and international express companies to ensure transportation quality.
- After receiving the goods, please handle with care and check whether the outer carton is in good condition. Carefully open the outer carton and check whether the packing boxes are in alignment. Take a picture before you take them out.
- Please open the vacuum package in a clean room when the products are to be applied.
- If the products are found damaged during courier, please take a picture or record a video immediately. DO NOT take the damaged products out of the packaging box! Contact us immediately and we will solve the problem well.
