​​Customized High Borosilicate Glass Wafers ​​High Refractive Index Substrates 2-12 Inch

The core of manufacturing high borosilicate glass wafers lies in ​​precise composition control, high-temperature uniform melting, low-damage forming, and stress relief annealing​​. By leveraging their inherent characteristics of "low expansion and high temperature resistance," this process ultimately produces precision substrates with high flatness and low defects, serving high-end fields such as optics, MEMS, and semiconductors.
 

Precise control at every process step—from minor adjustments to raw material ratios to the exact regulation of annealing rates—directly determines the thermal stability and surface precision of the wafers. Only through strict adherence to these critical stages can the stringent demands of high-end applications, including optical instruments and micro-nano devices, for "ultra-precision and high-reliability" substrates be met.

I,Chemical Composition Comparison

Summary: High borosilicate glass has boron added, significantly improving its thermal stability and chemical resistance.

II,Performance Differences

Compared to other wafer materials, high borosilicate glass wafers offer multiple advantages:

• ​​Excellent thermal resistance​​: Maintains durability under extreme temperature fluctuations, preventing cracking or damage.
• ​​Corrosion and chemical resistance​​: Resists chemical degradation.
• ​​High flatness​​: Ensures precision in microscale applications.
• ​​Thermal shock resistance​​: Adapts to thermal expansion, making it ideal for microelectromechanical systems (MEMS).

​​High Borosilicate Glass Wafers​​ Core Application Fields​​

1. Optics and Precision Instruments​​

• Used to manufacture ​​precision optical lenses, prisms, and optical fiber preforms​​, where its low expansion coefficient avoids optical path deviation caused by temperature changes.
• High-end microscope and spectrometer slides and observation windows.

2. ​​New Energy and Photovoltaics​​

• Core material for ​​solar collector tubes​​, enduring high temperatures (>200°C) with thermal expansion matching the tube’s internal medium to reduce thermal stress-induced cracking.
• Premium photovoltaic glass, utilizing its high light transmittance and anti-aging properties to enhance power generation efficiency.

3. ​​Medical and Laboratory​​

• Pharmaceutical ampoules and vaccine vials (resistant to chemical corrosion, preventing drug-glass interactions; withstands high-temperature sterilization up to 180°C dry heat).
• Laboratory high-temperature furnace tubes and crucibles (replacing quartz glass with lower cost and superior thermal shock resistance).

4. ​​High-End Home and Industrial​​

• Heat-resistant glass cookwar, directly exposed to open flames or sudden temperature changes.
• Industrial high-temperature observation windows, enduring long-term high temperatures and thermal cycling without failure.
