Domestic Alkali-Free Glass
Domestic alkali-free glass is a specialized type of glass characterized by its low alkali oxide content, typically less than 0.1%. This composition provides several advantages, particularly in high-tech applications.
-
High Chemical Stability: Alkali-free glass exhibits excellent resistance to chemical corrosion, making it suitable for use in harsh environments and applications where chemical durability is essential
-
Low Thermal Expansion: This type of glass has a low coefficient of thermal expansion, which allows it to maintain dimensional stability under varying temperature conditions, reducing the risk of cracking or deformation.
-
Enhanced Mechanical Strength: Alkali-free glass is known for its superior mechanical strength, which makes it ideal for applications requiring durability and resistance to impact.
-
Excellent Optical Clarity: The glass provides high transparency and clarity, making it suitable for optical applications such as display screens and lenses.
-
Environmentally Friendly: Being free from hazardous alkali metals, alkali-free glass aligns with modern environmental standards, making it a safer choice for both manufacturers and consumers.
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.
