Gorilla® glass is an aluminosilicate glass ,It is not much different from ordinary glass in terms of appearance, but the performance of the two is completely different after chemical strengthening,which makes it has better anti-bending,anti-scratch,
anti-impact,and high clarity performance.
Why Gorilla® glass is so strong?
Because of its ion exchange during chemical strengthening, creating a strong structure
In fact, in the production of Gorilla® glass, the soda lime glass produced is placed in a potassium nitrate solution to complete ion exchange. The process is quite simple in terms of chemical principles. The potassium ions in potassium nitrate are used to convert the glass into In this way, the potassium ion has a larger structure and its chemical properties are more active, which means that the new compound generated after the sodium ion is replaced has higher stability. and higher strength. In this way, a dense reinforced compressive layer is formed, and the stronger chemical bonds of potassium ions also give Gorilla® glass flexibility. In the case of slight bending, its chemical bonds will not be broken. After the external force is removed, the chemical bond is reset again, which makes Gorilla® glass very strong

Type of Gorilla® Glass
Gorilla® Glass 3 (2013)
Gorilla® Glass 5 (2016)
Gorilla® Glass 6 (2018)
Gorilla® Glass DX/DX+ (2018) - For wearables and smartwatches
Gorilla®Glass Victus (2020)
What is difference between those type of glass?
Gorilla® Glass 3 provides up to a 4x improvement in scratch resistance when compared to competitive aluminosilicate glasses from other manufacturers
Gorilla® Glass 3+ improves drop performance by up to 2X versus current alternative glasses designed for the value segment, and, on average, survives a 0.8-meter drop (waist height) onto a hard and rough surface up to 70% of the time
Gorilla® Glass 5 survives up to 1.2-meter, waist-high drops onto hard, rough surfaces, Gorilla® Glass 5 also delivers up to 2x improvement in scratch performance compared to competitive aluminosilicate glass
Gorilla® Glass 6 survived drops from up to 1.6 meters onto hard, rough surfaces. Gorilla® Glass 6 also delivers up to 2x improvement in scratch performance compared to competitive aluminosilicate glass
Gorilla® Glass with DX and Gorilla® Glass with DX+ answer the call by enhancing display readability through a 75% improvement in front surface
reflection,versus standard glass,and increasing the display contrast ratio by 50% with the same display brightness level, These new glasses boast of an anti-reflective property which, offers better visibility while also improving scratch resistance
Gorilla® Glass Victus® — the toughest Gorilla® Glass yet, with significant improvement in both drop and scratch performance, Gorilla® Glass Victus® survived drops onto hard, rough surfaces from up to 2 meters. Competitive aluminosilicate glasses, from other manufacturers, Additionally, the scratch resistance of Gorilla Glass Victus is up to 4x better than competitive aluminosilicate
Speaking of so many advantages of Gorilla® Glass,does it actually have any disadvantage?
The only disadvantage is high price,base one same glass size,cost made from Gorilla® Glass will be around 5-6 times higher than normal soda lime glass
Is there any alternative?
There is Dragontrail glass/Dragontrail glass X from AGC, T2X-1 from NEG, Xensation glass from Schott,Panda glass from Xuhong.they all have outstanding performance in scratch resistance and durability with comparatively lower price
