Gorilla Glass

 

Scratch resistant and crack resistant glasses are a must when choosing mobile phones these days. And gorilla glass is the most famous and mostly used brand for glasses for phone screens. There are also brands like Dragontrail and Xensation, but are not widely used by mobile phone brands these days.

 

Gorilla glass is a brand of chemically strengthened glass developed and manufactured by Corning. It is manufactured in Harrodsburg in Kentucky, Asan in Korea, and Taiwan. Corning Incorporated is an American multinational technology company that specializes in speciality glass, ceramics, and related materials and technologies including advanced optics, primarily for industrial and scientific applications. The company was named Corning Glass Works until 1989.

 

Gorilla glass is an alkali -aluminosilicate based sheet glass, used primarily for screen covers for phones and tablets, television screens etc. The glass gains its strength, ability to contain flaws and crack resistance by being immersed in a propriety, hot, potassium salt, ion exchange bath.

 

There are almost 9 versions of the glass launched through out the years since 2010.

Manufacture

During the manufacturing process, the glass is toughened by ion exchange. The material is immersed in molten alkaline potassium salt at a temperature of approximately 400 C. The 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, giving the glass surface increased strength, ability to contain flaws and overall crack resistance.
