Key Features

1. 1. 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.

1. 1. 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).

1. 1. Estabilidad química: 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.

1. 1. Smooth Surface Finish: Glass substrates produced from alkali-free materials have flat precision surfaces, which are essential for high-quality optical and electronic applications.

1. 1. Environmentally Friendly: This type of glass is free from hazardous substances like arsenic (As) and antimony (Sb), aligning with modern environmental standards.

Applications

• • Tecnología de visualización: 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.
