Transcript of Gorilla Glass
Example of Gorilla Glass:
In what the alkali-aluminosilicate sheet glass is used?
The alkali-aluminosilicate sheet glass is used primarily as cover glass for portable electronic devices, including mobile phones, portable media players, portable computer displays, and some television screens. It is manufactured in Harrodsburg, Kentucky, US; Asan, Korea; and Taiwan.
What does the Gorilla Glass gains?
The glass gains its surface strength, ability to contain flaws, and crack-resistance by being immersed in a hot potassium salt ion-exchange bath.
What is a Gorilla Glass?
During its manufacture, the glass is toughened by ion exchange. The material is immersed in a molten alkaline potassium salt at a temperature of approximately 400 °C (750 °F), wherein smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions occupy more volume and thereby create a surface layer of high residual compressive stress at the surface, giving the glass surface increased strength, ability to contain flaws, and overall crack-resistance, making it resistant to damage from everyday use.

Corning experimented with chemically strengthened glass in 1960, as part of a "Project Muscle" initiative. Within a few years they had developed a "muscled glass"marketed as Chemcor. The product was used until the early 1990s in commercial and industrial applications, including automotive, aviation and pharmaceutical uses, notably in approximately one hundred 1968 Dodge Dart and Plymouth Barracuda racing cars, where minimizing the vehicle's weight was essential. Experimentation was revived in 2005, investigating whether the glass could be made thin enough for use in consumer electronics. It was brought into commercial use when Apple asked Corning for a thin, toughened glass; it was used in the new iPhone.
