Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension .
Toughened glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. [6] Tempering, by design, creates balanced internal stresses which causes the glass sheet, when broken, to crumble into small granular chunks of similar size and shape instead of splintering into random, jagged shards.
Also unlike toughened glass, chemically strengthened glass may be cut after strengthening, but loses its added strength within approximately 20 mm of the cut. Similarly, when the surface of chemically strengthened glass is deeply scratched, this area loses its additional strength. Another negative of chemically strengthened glass is the added cost.
Gorilla Glass DX+ was first used on the Samsung Galaxy Watch. [51] Gorilla Glass 3+ was introduced in August 2019. [52] It was designed for intermediate and value-segment mobile devices, and its drop performance bridges the gap between Gorilla Glass 3 and Gorilla Glass 5 in this market segment. [52] Gorilla Glass Victus was introduced in July ...
The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, [4] which pioneered the technique in the 1950s at their production site in St Helens, Merseyside. [5] Modern windows are usually made from float glass, [6] though Corning Incorporated uses the overflow downdraw method. [7]
Safety and security films are used where there is a potential for injury from broken glass (such as glass doors or overhead glazing). These films can be applied to toughened, annealed, or laminated glass. They are available in various thicknesses, from 100 micrometers (or 4 mils minimum 2 ply) through to 525 micrometers + (21 mils).
Glass fibers have a much higher tensile strength than regular glass (200-500 times stronger than regular glass). [7] This is due to the reduction of flaws in glass fibers [ 8 ] and the small cross sectional area of glass fibers, constraining maximum defect size.
The third-generation iPhone SE has a similar design to the iPhone 8 and similar internal hardware components to the iPhone 13 series, including the A15 Bionic system-on-chip [10] and 5G connectivity. The third-generation iPhone SE is the last iPhone to feature 4 GB of RAM, as well as 64 GB of internal storage, and single lens rear camera.
