Elevate Your Technology with Alkaline-Free Glass Wafers The Ultimate Solution for High-Temperature Processes and Beyond
In the ever - evolving world of microelectronics, photonics, and optoelectronics, the choice of materials can make or break your project. Our Alkaline - Free Glass Wafers are here to take your innovations to new heights.
Alkaline - free glass offers a multitude of advantages. It exhibits extremely low levels of alkali metal ions, which can otherwise cause undesirable effects like ion migration and device degradation. This makes our wafers ideal for high - precision applications such as thin - film transistor (TFT) displays, where image quality and long - term stability are crucial.
These wafers also boast excellent optical properties, with high transparency across a wide range of wavelengths. They are perfect for optical waveguides, sensors, and other photonic devices.
We employ advanced manufacturing processes to ensure the wafers have a smooth surface, uniform thickness, and minimal defects. Choose our alkaline - free glass wafers and unlock the full potential of your advanced technologies. Contact us now to place your order.

FAQs:
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.
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.
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.
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.
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.
