Gorilla Glass is an alkali-aluminosilicate sheet toughenedglass that Corning Inc. developed and manufactures. Corning registered theGorilla Glass brand name as atrademark. Corning engineered Gorilla Glass to combine thinness,lightness, and damage-resistance. It is used primarily as the cover glass forportable electronic devices, including mobile phones, portable media players,portable computer displays, and some television screens. During manufacture, the glass is immersed in a molten alkalinesalt bath using ion exchange to create compressive residual stress at thesurface to reduce the glass' tendency to crack: for a crack to form, it wouldhave to overcome the compressive stress.
Corning experimented with chemically strengthened glass in1960, as part of a "Project Muscle" initiative. Within a few yearsthey had developed a "muscled glass" named "Chemcor"glass. The product was used until the early 1990s in various commercial andindustrial applications, including automotive, aviation and pharmaceuticaluses, with particular use in approximately one hundred 1968 Dodge Dart andPlymouth Barracuda racing cars, where minimizing the vehicle's weight isessential. Experimentation was revived in 2005, investigating whether theglass could be made thin enough for use in consumer electronics, it was broughtinto commercial use when Apple asked Corning for a toughened glass that wouldeventually go into the iPhone.
Corning further developed the material for a variety ofsmartphones and other consumer electronics devices for a range ofcompanies.
The manufacturer, Corning Inc., says that Gorilla Glass'material's primary properties are its high scratch resistance (protectivecoating), and its hardness (with a Vickers hardness test rating of 622 to701) — which allows thin glass without fragility. The material can also berecycled.
Gorilla Glass by 2010 had been used in approximately 20percent of mobile handsets worldwide, about 200 million units. The secondgeneration, called "Gorilla Glass 2", was introduced in 2012 and OnOctober 24, Corning announced that over one billion mobile devices used GorillaGlass. Gorilla Glass 2 is 20 percent thinner than the original GorillaGlass.
Gorilla Glass 3 was introduced at CES 2013. According toCorning, Gorilla Glass 3 is up to three times more scratch-resistant than theprevious version of the product, demonstrating an enhanced ability to resistdeep scratches that typically weaken glass. The promotional material forGorilla Glass 3 claims that it is 40% more scratch-resistant, in addition tobeing more flexible. Gorilla Glass 3 is the outcome of the first time thatCorning used atomic-scale modeling before the material was melted inlaboratories, with the prediction of the optimal composition attained throughthe application of rigidity theory.
The latest Gorilla Glass has silver ion doping that caneffectively kill over 90% of bacteria.
Corning has indicated that other areas of interest in futureimprovements include making it less reflective and less susceptible tofingerprint smudges, as well as changing the surface treatments and the way itis finished.
During its manufacture, Gorilla Glass is toughened by ionexchange. The material is submersed in molten potassium salt at a temperatureof approximately 400 °C (750 °F), whereby smaller sodium ions leave the glassto be replaced by larger potassium Ions from the Salt Bath. The larger Ionsoccupy more space and are pressed together when the glass cools, causingPotassium Ions to diffuse far into the surface, thereby creating a 'surface'layer of high compressive stress deep into the glass, a layer more resistant todamage from everyday use.
Corning manufactures Gorilla Glass in Harrodsburg, Kentucky(USA), Asan (Korea), and in Taiwan.
On October 26, 2011, Corning announced the commercial launchof Lotus Glass, designed for OLED and next-generation LCD displays. Theintrinsic thermal consistency of Lotus Glass allows it to retain its shape andquality during high-temperature processing. Decreased compaction and variationduring the crystallization and activation step to further reduce stress anddistortions to the substrate. This enables tighter design rules in advancedbackplanes for higher resolution and faster response time. According toCorning, Gorilla Glass is specifically a cover glass for the exterior ofdisplay devices while Lotus Glass is designed as a glass substrate to be usedwithin liquid crystal display panels. In other words, a product could use bothGorilla Glass and Lotus Glass. On February 2, 2012, Corning Incorporatedand Samsung Mobile Display Co., Ltd. signed an agreement to establish a new equityventure for the manufacture of specialty glass substrates for the organic lightemitting diode device market in Korea. The joint venture is based on LotusGlass.
In 2012 Corning introduced Willow Glass, a flexibleglass based on borosilicate glass, designed for use as a display substrateand recommended for use with Gorilla Glass as a cover glass.
I guess now you must be well know about what Gorilla Glass is?
So which Device are you using? And does it have Gorilla Glass Protection.
