Corning Gorilla Glass is changing the way the world thinks about glass. Its exceptional damage resistance helps protect today’s most sophisticated electronic devices from the scratches, drops, and bumps of everyday use.
Corning Gorilla Glass is currently featured on hundreds of the world’s coolest smart phones, tablets, and PCs – with TVs on the way.
Why do I want Corning® Gorilla® Glass on my devices?
Scrapes, bumps, and drops are a fact of life, but Gorilla Glass enables your device to resist damage from the abuses that come with everyday use. Gorilla Glass also has strong aesthetic appeal. It’s thin, lightweight, and cool to the touch – enabling the sleekest designs.
What makes Gorilla Glass so damage resistant?
The unique composition of Gorilla Glass allows for a deep layer of high compressive stress (created through an ion-exchange process). This compression acts as a sort of “armor,” making the glass exceptionally tough and damage resistant.
Can you explain the ion-exchange process?
Ion exchange is a chemical strengthening process where large ions are “stuffed” into the glass surface, creating a state of compression. Gorilla Glass is specially designed to maximize this behavior.
The glass is placed in a hot bath of molten salt at a temperature of approximately 400°C. Smaller sodium ions leave the glass, and larger potassium ions from the salt bath replace them. These larger ions take up more room and are pressed together when the glass cools, producing a layer of compressive stress on the surface of the glass. Gorilla Glass’s special composition enables the potassium ions to diffuse far into the surface, creating high compressive stress deep into the glass. This layer of compression creates a surface that is more resistant to damage from everyday use.
