Contact SupplierAluminosilicate glass is a type of glass that contains aluminum oxide, usually at levels between 20% and 40%. It has several properties that make it suitable for various applications, such as:
Â
High strength and scratch resistance: Aluminosilicate glass is chemically strengthened by an ion exchange process that increases its surface compressive stress and hardness. It is often used for touchscreens and touchscreen protectors12.
Â
Resistance to high temperature: Aluminosilicate glass can withstand temperatures up to 800°C and has a high softening point of 1010°C. It is comparable to ceramics in terms of thermal resistance12.
Â
Resistance to chemical degradation: Aluminosilicate glass has a low dissolution rate and a high chemical durability. It can resist corrosion and erosion by acids, alkalis, and salts12.
Â
Resistance to thermal shock: Aluminosilicate glass has a low coefficient of thermal expansion, which means it does not expand or contract much when heated or cooled. It can be used as a sealing material for hot systems and equipment12.
Â
There are different types of aluminosilicate glass, depending on their chemical compositions and oxide content. Some examples are alkaline earth aluminosilicate glass, alkali aluminosilicate glass, e-glass, aluminoborosilicate glass, and gorilla glass12. Each type has its own specific properties and applications.
