Japan has developed a new type of glass with super metal hardness

on November 5, according to foreign media reports, Japanese scientists have developed a kind of super hard glass to avoid damage caused by the action of hydraulic chuck due to error operation. The test results show that its hardness is higher than that of iron, copper and even stainless steel. It can be used to make screens lighter and thinner. In addition, it can also be used to make car windscreens, windows of buildings and so on. Atsunobu masuno, the project leader and professor of the Institute of Industrial Sciences of the University of Tokyo, said: "we are looking for ways to produce this new material on a large scale. We believe that this technology is expected to be commercially available within five years."

super strong glass comes out, and mom doesn't have to worry about you breaking the screen anymore.

the days when superheroes throw villains out through glass windows may be gone forever: scientists from the production technology research of the University of Tokyo have developed a new type of mixed glass, which is as strong as steel and is almost unbreakable. The study was published in the journal scientific reports

the strength of this new type of glass is reflected in the difficulty of deformation caused by external forces (such as hitting with bricks). The elastic modulus of this new type of glass is equivalent to that of steel, and its hardness is also very strong. This is another indicator of strength - it is not easy to scratch this kind of glass

don't worry about breaking the screen anymore

the reason why it has this ability is that it contains aluminum oxide, which is famous for its hardness. Alumina is a mineral corundum, whose Mohs hardness is second only to that of diamond. The properties of alumina have been well known for a long time, and it is difficult to add it to glass chemically. Previously, when materials scientists tried to mix alumina and glass, they added the mixed liquid into a container. Unfortunately, this liquid will crystallize preferentially at the edges and corners, which have not been mixed well with glass

when the liquid has crystal nuclei, the liquid will crystallize and become a solid. For example, water only begins to condense into ice near a small solid particle. In order to solve the problem of alumina, Japanese scientists use oxygen to suspend glass and alumina in the air, so that they can solidify without nucleation points

use a carbon dioxide laser to melt the two substances together to form a glass with 50% alumina content. This technology is called pneumatic suspension technology, which can produce completely transparent, light and thin glass with excellent optical properties

"we hope to commercialize this technology in the next five years." Atsunobu masuno, an assistant professor at the University of Tokyo, said

this is undoubtedly good news for users who touch the innovative bicycle tire system that elastopan uses to further improve the utilization of non-metallic materials and solutions in cars, reducing the weight by about 30%, which can greatly reduce the risk of screen fragmentation. More miraculously, this new material will mean that when the glass falls on the ground, a crack will be broken in the marble, while your glass is safe. Skyscrapers built with this kind of glass can have stronger resistance to natural disasters
