Everyone knows that: Corning® Gorilla® Glass Victus® — the toughest Gorilla® Glass
In Sept 2022, Huawei unveiled the Mate 50 series smartphone, one of the Highlights od the Mate 50 is: The Microcrystals Glass: The Secret Behind Huawei`s Unbreakable Smartphones.
Kunlun glass produces hundreds of millions of nanocrystals through composite ion strengthening injection technology, which greatly improves the toughness of glass, and then is made after 24 hours of high-temperature nanocrystal growth, 108 microcrystalline raw materials and panel processing processes, and 1600 degrees platinum precious metal melting technology.
On Oct 26,2023,Xiaomi conference, Xiaomi launched “Xiaomi Dragon Crystal Glass”. Xiaomi claimed that this is “Xiaomi’s strongest protective glass ever”, compared to Apple`s super porcelain Crystal glass, the strength is increased by 5% and the drop resistance is increased by 20%.
Lei Jun announced the dimensional hardness parameters of “Xiaomi Dragon Crystal Glass”:
Xiaomi Longjing Glass 860 (HV 0.025)
Kunlun 2nd generation glass 830 (HV 0.025)
Apple Super Ceramic Glass 814 (HV 0.025)/Corning® Gorilla® Glass Victus® 2
GGV2 670 (HV 0.025)
In terms of technology, Lei Jun claimed that Xiaomi R&D personnel added special powder to quartz sand, heated it to 1,600 degrees Celsius, smelted it for 100 hours, and then went through the crystal growth process, which took about 80 hours.
Lei Jun demonstrated the effect of Xiaomi Dragon Crystal Glass under an electron microscope, claiming that these crystals “can effectively block cracks and greatly increase the hardness”:
Billions of nanoscale microcrystals are firmly interlocked to effectively prevent cracks
A higher proportion of hard components and crystal structure improves material hardness
The Suppliers of Kunlun Microcrystals Glass and Dragon Microcrystals Glass have been listed in Haythink`s Suppllier Database.
