Technology behind reinforced glass for screens

Gorilla Glass is a brand of chemically strengthened glass manufactured by Corning. The hardness is obtained through an ion exchange process. This involves immersing the glass in a hot bath of molten potassium salt at about 400°C. Smaller sodium ions in the glass are replaced by larger potassium ions. This creates a surface with high compressive stress, which makes the glass highly scratch-resistant and durable, ideal for displays of electronic devices.

Consumer Electronics

The glass is widely used as a protective layer for the screens of smartphones, laptops, tablets and wearables. Its combination of scratch resistance, thinness and clarity makes it a standard choice for wearable devices that are subject to heavy use.

Automotive industry

In the automotive industry, it is used for lighter and more durable windshields and interior displays. Its lower weight compared to traditional glass contributes to lower overall vehicle weight, which can improve fuel efficiency.

Aviation

The material is also used in aviation, for example for the inner layers of cockpit windows. Its high strength and low weight offer significant advantages over conventional laminated soda lime glass in demanding aviation environments.

Semiconductor industry

Within semiconductor manufacturing, the glass is used as a substrate for photomasks. Here, the material's thermal stability and optical purity are crucial for creating highly accurate patterns on integrated circuits.

High scratch resistance

The high compressive stress on the surface makes the glass highly resistant to scratches and damage from everyday use. This significantly increases the durability and longevity of screens, even when in contact with sharp objects.

Thin and lightweight

The glass can be produced extremely thin without sacrificing strength. This is an essential advantage for the design of modern, slim and lightweight electronic devices such as smartphones and smartwatches.

Ion exchange process

At the heart of the technology is a chemical tempering process. Replacing sodium ions in the glass with larger potassium ions from a salt bath creates a compressed surface layer that acts as a protective armor against cracking.

Continuous product development

Corning is constantly bringing new generations to market, such as Gorilla Glass Victus. Each new version offers improved performance in terms of drop and scratch resistance, specifically tailored to the increasing demands of modern devices.
