In previous posts, we have discussed what soda-lime glass is, one of the most common and widely used materials.
So let's talk today, aluminum silica glass
What made up Aluminumsilica Glass ?
Compared to ordinary glass, the aluminum-silica glass in the Al2O3 and SiO2 content is very high, both of which are favorable to improve the performance of the glass.
Aluminum-silicate glass has a higher transmittance (up to 98.9%) than ordinary glass, a better chemical stability and electrical insulation and mechanical strength and low coefficient of thermal expansion . The
Do you know how many kinds of Aluminumsilica Glass ?
Aluminum-silica glass, divided into 3 kinds :
① High Aluminumsilica Glass
② Medium Aluminumsilica Glass
③ Low Aluminum Glass.
The difference between them just only composition.
Among them, the high-alumina glass of Al2O3 and SiO2 have the highest percentage. As a result, high-alumina glass has the best transmittance (>98%) and the lowest coefficient of thermal expansion, followed by meso-alumina glass and low-alumina glass.
But , even low aluminum glass can achieve a transmittance of at least 91%.
The main properties of Aluminumsilica Glass:
Below, let's take a look at several major performance indicators of aluminum-silicate glass:
Transmittance: ＞91.8% ; ＞95%； ＞98.9%
Refractive index: 1.5325 (yellow light)
Softening temperature: 600-900°C
Flexural strength: 450-500Mpa
Expansion coefficient: 50X10-7/°C (20~100°C)
Thermal shock resistance temperature: 250~300℃
The advantages of Aluminumsilica Glass:
Due to the excellent properties of aluminum-silica glass with high transmittance and high clarity. Therefore, LCD screens, electronic displays, touch screens, face recognition equipment and cell phone screens tend to use aluminum silica glass. It can be the most authentic, the most realistic restoration of the true color.
The famous Aluminumsilica Glass brand:
Flat aluminum-silica glass, the most typical is Corning Gorilla.
What’s more , AGC and SCHOTT also famous .
We most often use the Corning Gorilla sheet, this one in our customers a lot of praise.
