Key Features
Low Alkali Content: The minimal presence of alkali oxides ensures that the glass does not degrade the properties of thin films, making it suitable for sensitive electronic applications.
High Thermal Dimensional Stability: Alkali-free glass exhibits a high strain point and a low thermal expansion coefficient, allowing it to maintain dimensional stability during high-temperature processes, such as those used in the production of liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs).
Chemical Stability: The glass is chemically inert, making it resistant to various treating agents used in semiconductor processes. This property helps maintain the quality of the surface during manufacturing.
Smooth Surface Finish: Glass substrates produced from alkali-free materials have flat precision surfaces, which are essential for high-quality optical and electronic applications.
Environmentally Friendly: This type of glass is free from hazardous substances like arsenic (As) and antimony (Sb), aligning with modern environmental standards.
Applications
Display Technology: Used as substrates for LCD and OLED displays, where dimensional stability and surface quality are critical.
Thin Film Formation: Suitable for various thin film applications in electronics due to its chemical stability and low alkali content.
Semiconductor Manufacturing: Employed in processes that require high precision and resistance to chemical treatments.
Overall, domestic alkali-free glass is an essential material in the electronics industry, providing reliability and performance in advanced display technologies and semiconductor applications.
