What physical and chemical properties create Gorilla Glass?

What physical and chemical properties create Gorilla Glass?

Gorilla Glass is composed of an oxide of silicon and aluminum—also called aluminosilicate glass—along with sodium ions (Fig. 2). Figure 2. Gorilla Glass, which is used in smartphone displays, is a type of glass that is strengthened by the addition of potassium ions, which replace smaller sodium ions.

What properties does Gorilla Glass have?

Gorilla Glass has four main properties: hardness, thinness, lightness, and scratch resistance. On the Mohs scale of mineral hardness, Gorilla Glass rates a nine. For comparison, diamond—the hardest element in the world—rates a 10 on the Mohs scale. Regular glass rates a seven and is much softer.

Why is Gorilla Glass so strong?

Gorilla Glass’ composition enables the potassium ions to diffuse far into the surface, creating high compressive stress deep into the glass. This layer of compression creates the surface that is more resistant to damage. One of Corning’s greatest strengths is its focus on developing the technology behind the glass.

What are the properties that make gorilla glass so important and what are its applications?

Gorilla Glass is a scratch-resistant and durable glass product from Corning that is used to protect the screens of tablets, smartphone and other mobile devices. The glass is lightweight, strong and compatible with touch screen technologies. As a result of its strength, screens made of Gorilla Glass can be very thin.

Is Gorilla glass a polymer?

[Photo: courtesy of Lenovo] However, all of these early foldable devices have one design flaw. They use a plastic polymer for the display cover, which is less hard than glass and therefore easier to scratch, warp and even gouge during use.

Is Gorilla Glass made of sand?

Making Gorilla Glass. Glass is made up of sand, plain and simple. Sand, or silicon dioxide, is melted down with limestone and sodium carbonate to create crude glass. Before the process of ion exchange, the glass must be made to that all important thinness needed to be useful in cell phones and other mobile devices.

What is Gorilla Glass 3 protection?

The Gorilla Glass 3 with Native Damage Resistance (NDR) technology was announced back in 2013. The glass is a thin sheet of alkali-aluminosilicate that makes the glass tougher and scratch resistant. With the improved damage resistance, the glass can survive pressures, deep cuts and scratches.

Is Gorilla Glass a polymer?

Is Gorilla Glass tempered glass?

Corning gorilla glass is stronger than tempered glass; however, not all smartphone glasses come with the former glass attached to it. In such cases, you can protect your screen with a good-quality tempered glass.

How is Gorilla Glass strengthened?

Gorilla Glass is strengthened using an ion-exchange process which forces large ions into the spaces between molecules on the glass surface. Specifically, glass is placed in a 400°C molten potassium salt bath, which forces potassium ions to replace the sodium ions originally in the glass.

What is the difference between Gorilla Glass and AGC Glass?

Gorilla Glass. Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning, now in its sixth generation, designed to be thin, light and damage-resistant. Gorilla Glass is unique to Corning, but close equivalents exist, including AGC Inc. Dragontrail and Schott AG Xensation.

What is the difference between Gorilla Glass 2 and 3?

Gorilla Glass 2 is a newer form of Gorilla Glass that is up to 20\% thinner than the original material, yet still as tough. Gorilla Glass 3 resists deep scratches and is more flexible than its predecessors.

What is the history of Gorilla Glass?

Gorilla Glass isn’t a new invention. Actually, the glass, originally named “Chemcor”, was developed by Corning in 1960. At that time its only practical application was for use in racing cars, where strong, lightweight glass was needed. In 2006, Steve Jobs contacted Wendell Weeks, the CEO of Corning, seeking a strong,…
