Difference Between Gorilla Glass And Heat Strengthened Glass. In this article, you will come to know about what is gorilla glass, what is heat strengthened glass, what is the main difference between gorilla glass and heat strengthened glass, and much more.
Both the terms gorilla glass and heat strengthened glass are the types of glasses that are used in construction and for different purposes. Glass is a transparent substance that can be transparent, translucent, or brittle. The process that is used to manufacture the glass is known as the ‘fusion process’. In this process, the sand is fused with soda, lime, and various admixtures. Then this mixture is cooled rapidly, thus forming a glass.
The difference in the glasses lay in their making process. Here, we will first discuss the main difference between gorilla glass and heat strengthened glass, then differentiate between them in detail.
What Is The Main Difference Between Gorilla Glass And Heat Strengthened Glass?
The main difference between gorilla glass and heat strengthened glass is that the:
-Gorilla glass is a type of toughened glass. It is made by the material alkali-aluminosilicate, which is formed by bonding aluminium, silicon, and oxygen together.
-Heat Strengthened glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi, which makes it stronger than annealed glass.
What Is Gorilla Glass?
Gorilla glass is a type of toughened glass. It is made by the material alkali-aluminosilicate, which is formed by bonding aluminium, silicon, and oxygen together. The glass is placed in a molten salt bath for up to 400 degrees celsius. This high degree temperature triggers an ion exchange process. This forces the smaller sodium ion out of glass, eventually replacing them with larger potassium ions drawn in from salt. This makes the glass denser, giving it strength and flexibility.
Gorilla glass is developed by Corning Inc. It is a durable glass product that is used to protect the screens of smartphones, tablets, and other smart devices from scratches or cracks, thus increasing the durability of your smartphone screen. Gorilla glass is very lightweight, strong and compatible with touch screen technologies. It was first implemented in 2007 on the iPhone.
Gorilla glass is not really unbreakable, however, it is incredibly strong. The latest 6th generation of gorilla glass can survive 15 drops up to 1 meter high onto hard surfaces. It also has gone through rigorous testing by Corning Inc for flexibility, scratch resistance, and impact protection.
What Is Heat Strengthened Glass?
Heat Strengthened Glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi for 6mm glass, which makes it stronger than annealed glass. It has more resistance to thermal loads and is stronger as compared to annealed glass.
This glass is also referred to as semi-tempered. That’s why it cannot be used as a safety glass. It cannot be cut, drilled, edge-ground, or sandblasted after the heat strengthening. Heat-strengthened glass is shattered like tempered glass, however, it got fractured into dangerous large shards.
What Are The Properties Of Glass?
The 6 main properties of glass are as under:
1.Transparency:
The main property of glass is transparency. The transparent the glass, the better the vision of that glass. Usually, the glasses are transparent from both sides, but there is some glass that is transparent from one side only. An example of such types of glasses are mirrors that have only one side transparency.
2.Strength:
The strength of glass is the second property of glass. It depends on the modulus of the ruptured value of glass. The glass is very brittle initially. We add admixtures and laminates to make it more stronger.
3.Workability:
The workability of the glass is a superior property. Glass can be moulded into any shape when melted.
4.Transmittance:
A glass should have visible transmittance property. It means that a visible fraction of light should pass through the glass.
5.U-value:
The u-value of the glass is the amount of heat that can be passed through the glass. Like, if the glass is insulated the glass will have a lower u-value.
6.Recyclable:
A glass can always be recycled. It has 100% recyclable property. It is used as a raw material in the construction industry.
