CHIYAN Crystal Glass Ceramic for Ceramic Phone Screen Display Cover
Glass-ceramic (CHIYAN-C1) is a lithium alumino silicate glass-ceramic. Based on the special material design and nano-level crystallization scheme, this product has extremely high inherent strength, combining the toughness of ceramics with the high permeability of glass. High hardness and low expansion improve product processability. The extremely high inherent strength and optimized chemical strengthening design give it excellent drop resistance.
Characteristics:
Excellent optical properties
Super bending performanc
Good scratch resistance
Glass-ceramic is a material that combines the properties of glass and ceramic, and is created by crystallizing glass through a controlled heat treatment:
Composition
Glass-ceramics are made up of a glass matrix with a fine crystalline phase dispersed throughout.
Properties
Glass-ceramics have improved physical and mechanical properties compared to the original glass, such as increased strength, wear resistance, and thermophysical characteristics. They also outperform metals and polymers in terms of biological, dielectric, thermal, and chemical properties.
Manufacturing
Glass-ceramics are made by melting glass and then controlling the crystallization process. The crystallization process is carefully regulated to create a uniform dispersion of crystals throughout the material.
CHIYAN-C1’s 0.25mm~20mm thickness high alumino-silicate glass has already been used in the market to meet a wide range of customers needs.
Application:
It can be used in High-end Smartphones, Tablet PC and High-end Display Covers
Regular Thickness:
0.25mm~20mm
Standard Size:400*500mm
Note: The size can be customized according to customer's needs.
