With the rapid development of optoelectronic technology, high borosilicate glass is becoming the core material of the new generation of optoelectronic products due to its unique optical properties and physical characteristics. This special glass with low expansion coefficient, high transmittance, and excellent thermal stability is bringing revolutionary innovation opportunities to the optoelectronic industry.
1、 Core performance advantages
Excellent optical properties: visible light transmittance of over 92%, good transparency in both ultraviolet and infrared bands
Ultra low thermal expansion: 3.3 × 10 ⁻⁶/℃ expansion coefficient, ensuring dimensional stability at extreme temperatures
Excellent mechanical strength: The bending strength reaches 90-110MPa, which is 2-3 times that of ordinary glass
2、 Key application areas
New Display Technology:
As an ideal substrate material for Micro LED and Mini LED
Support layer solution for flexible displays
Augmented reality (AR) optical waveguide core material
Optical communication devices:
Key components of fiber optic connectors
Preferred material for optical module packaging
5G base station optical device carrier
Photovoltaic new energy:
Efficient solar cell cover glass
Concentrated Photovoltaic System (CPV) Optical Components
Building Integrated Photovoltaics (BIPV) modules
3、 Technological development trends
Surface modification technology: improving surface hardness (up to 9H) and anti reflection performance through nano coating
Composite Processing Technology: Breakthrough in Precision Packaging Technology with Metal, Ceramic and Other Materials
Ultra thin development: The mass production technology of 0.1mm ultra-thin high borosilicate glass is becoming increasingly mature
4、 Market Outlook
According to market research institutions' predictions, the global market size of high borosilicate glass for optoelectronics will exceed 5 billion US dollars by 2025, with a compound annual growth rate of 12.8%. Among them, the Asia Pacific region will become the largest consumer market, accounting for over 45%. With the continuous emergence of new optoelectronic applications, high borosilicate glass will experience explosive growth in the following fields:
Vehicle display system
Smart wearable devices
Industrial laser equipment
Quantum communication devices
At present, China's high borosilicate glass industry is in a critical transition period from "following" to "running in parallel". It is recommended that relevant enterprises increase their research and development investment in key technologies such as precision molding and surface treatment, while strengthening strategic cooperation with downstream optoelectronic application manufacturers to jointly promote the innovative development of this strategic material. In the future, with the continuous optimization of preparation processes and cost reduction, high borosilicate glass will undoubtedly demonstrate greater application value in the field of optoelectronics.
