Elevate Your Technology with Our Single Crystal Quartz Wafers for High-Performance Oscillators Filters and Sensors

 

‌Single Crystal Quartz: The Pinnacle of Precision and Performance‌

     Transform your high-tech applications with ‌Single Crystal Quartz‌, the industry benchmark for unparalleled stability, purity, and piezoelectric excellence. Engineered to thrive in extreme conditions, our single crystal quartz products are the cornerstone of innovation in optics, electronics, and advanced manufacturing.

‌Key Advantages of Our Single Crystal Quartz‌

  • ‌Exceptional Material Properties‌: With ultra-low thermal expansion, high chemical resistance, and superior optical transparency (UV to IR), our quartz ensures reliability in corrosive, high-temperature, or vacuum environments.
  • ‌Precision Piezoelectric Performance‌: Ideal for frequency control devices, sensors, and oscillators, offering stable resonance and minimal energy loss for 5G, IoT, and aerospace systems.
  • ‌Customizable Solutions‌: Available in orientations (Z-cut, AT-cut, SC-cut), diameters (5mm to 150mm), and surface finishes (optical polish, metallized coatings, or etched patterns).
  • ‌Rigorous Quality Assurance‌: Each crystal is verified via X-ray diffraction, laser interferometry, and defect mapping to meet MIL-STD-883 and IEC standards.

‌Applications Redefined‌
From semiconductor lithography stages and laser optics to SAW/BAW filters and precision timing devices, our single crystal quartz enables breakthroughs in:

  • ‌Telecom‌: Low-jitter resonators for 6G infrastructure
  • ‌Medical‌: High-resolution ultrasound transducers
  • ‌Defense‌: Ruggedized IR windows and laser guidance systems
  • ‌Quantum Tech‌: Ultra-stable substrates for qubit integration

FAQs:

 

  1. 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.

 

  1. 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.

 

  1. 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.

 

  1. 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.

 

  1. 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.
