Gorilla Glass Victus
At the end of July 2020, Corning Incorporated Introduced Gorilla Glass Victus, the newest member of the Gorilla Glass family. According to the company, both the drop and scratch resistance of this new glass has been significantly improved. Gorilla Glass is a brand of chemically reinforced glass, developed and manufactured by Corning.
The alkali aluminum silicate glass is mainly used as a cover glass for portable electronic devices, including mobile phones, portable media players, portable computer screens and television screens.
The trick lies in the manufacturing method, by which the glass is tempered with a patented ion exchange process. The material is immersed in a molten alkaline potassium salt with a temperature of about 400 °C. In addition, smaller sodium ions in the glass are replaced by larger potassium ions from the salt bath. The larger ions take up more volume and thus create a surface layer with a high residual pressure voltage. This leads to a super strong, tear-resistant glass surface, resistant to damage from daily use. In laboratory tests, Gorilla Glass Victus survived a fall of up to two meters on hard, rough surfaces. Competing aluminum silicate glasses from other manufacturers usually break down corning when they fall from less than 0.8 meters.
Samsung is expected to be the first to use Gorilla Glass Victus in the short term.
