Chinese scientists manufacture an ultra-hard glass that is more resistant than diamond and that could be used in cell phone screens

One of the biggest headaches for smartphone users is the glass on the screen. Although the manufacturers of the different brands have improved the resistance of this material, in the same way they suffer ruptures with simple or strong blows when falling. So, to prevent this misfortune from happening, protectors and even insurance are sold that cover the partial damage of these glasses.

For this reason, science works to develop and later manufacture glass materials that are more resistant and that it is possible to use it in monitor screens, notebooks, tablets and cell phones. There have been advances in this area, but few such as that achieved by scientists from Jilin University in China.

A group of experts from this study house manufactured a carbon glass that is more resistant than natural diamond. According to information published Daily Mail it is ultra-hard and they synthesized it by designing it with a spherical fullerene molecule with the empirical formula; that is, the so-called buckyballs.

Buckyballs are a soccer ball-like form of carbon. This factory design was pressed with an anvil to put the material under really high pressures. In addition, it also reached high temperatures to form, which gave it that extremely resistant dye.

Glass resistance levels

The details that the scientists offer in their report is that the formation of this carbon glass was executed at 30 GPa (a measure of glass resistance) and at 1598 degrees Fahrenheit. Although, they explained, its production was also possible with different levels that varied between higher and lower.

So that you have an idea. The resistance that this carbon glass reached was 102 GPa. This level makes it the second strongest glass found or manufactured on Earth. It is only below the recently manufactured AM-III carbon with a support that reaches 113 GPa.

“The creation of a glass with such superior properties will open the door to new applications. The use of new glass materials depends on the realization of large pieces, which has been a challenge in the past. The comparatively low temperature at which we were able to synthesize this new ultra-hard diamond glass makes mass production more practical, ”said Yingwei Fei, geochemist author of the paper.

Likewise, with the manufacture of this glass, one of the great barriers that prevents the use of these materials in cell phones would be resolved. “The synthesis of an amorphous carbon material with three-dimensional bonds has been a long-standing goal. The trick is to find the right starting material to transform with the application of pressure, ”explained Fei.
