Gorilla Glass

Gorilla Glass, Gorilla Glass also Germanized or Gorilla glass is protected word mark for a thin chemically strengthened glass from the group of the U.S. manufacturer of Corning aluminosilicate glasses. It is mainly used as a cover glass for displays of portable electronic devices with a touch screen.

History, manufacture and properties

The glass with a thickness of 0.7 to 2 mm is characterized by a high breaking strength and scratch resistance. This is achieved by the hot alkaline salt melt into the near-surface glass layers compressive stresses are introduced by an ion exchange process in an about 400 ° C, which make it difficult to crack growth. During normal glass Newton shows cracks with a point load of 5, this occurs according to the manufacturer at this glass on only at the expense of about 40 Newtons. The situation is similar with the scratch resistance. According to the manufacturer, the product should be approximately two to three times more scratch-resistant than regular glass.

The manufacturer Corning had developed similar glasses in the 1960s, however, insists that Gorilla Glass is a new development, even if experience from the 1960s had been incorporated. Improved variants, which are marketed under the term Gorilla Glass 2, are also resistant to a thickness between 0.5 and 2.0 mm and slightly reduced density, but only soften at higher temperatures.
