Product Description
Durable and Precise Fused Silica Wafer with Low Thermal Expansion and High Surface Designed for Semiconductor Industry and Optical Coatings
For industries demanding the highest standards of optical clarity, thermal stability, and chemical resistance, our Fused Silica and Fused Quartz products deliver unmatched precision and reliability. Engineered from ultra-high-purity SiO₂, these materials excel in demanding applications across semiconductor manufacturing, laser systems, aerospace, and scientific research.
Our Fused Silica offers exceptional optical transmission (UV to IR wavelengths), low thermal expansion (0.55 × 10⁻⁶/°C), and superior resistance to thermal shock, making it ideal for high-energy laser optics, UV lithography, and harsh-environment sensors. Fused Quartz, renowned for its high-temperature durability (up to 1,200°C), provides excellent electrical insulation and chemical inertness, perfect for furnace components, crucibles, and semiconductor processing equipment.
Available in custom shapes, sizes, and surface finishes (e.g., polished, ground, or coated), our products meet stringent industry specifications for purity and dimensional accuracy. Whether for prototyping or large-scale production, we provide cost-effective, high-performance solutions tailored to your needs.
Elevate your applications with the gold standard in optical and thermal materials—choose our Fused Silica and Fused Quartz for uncompromising quality. Contact us today to discuss your project requirements!

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.
