Detection of super-hard glass near steel

According to the researchers, the Young module of the new glass - an index of hardness - is twice as high as ordinary glass oxide and nearly the same level of steel and iron.

New type of hardened glass near steel

Japanese scientists have developed a new type of hard-steel glass . This is a breakthrough that could lead to more durable glass and tabletop production.

"We will establish methods to put into mass production of this new material in the shortest time", professor Atsunobu Masuno Institute of Science & Industry (University of Tokyo) said, "We are looking to commercialize this technology within the next five years. "

Oxidized glass contains mainly silica , with increased hardness by adding alumina - also known as aluminum oxide . But scientists have found it difficult to create a glass of alumina-rich glass that precipitates when glass is exposed to the container. Alumina is the main factor to increase the durability of glass enamel : increase the tensile strength, reduce the thermal expansion, increase the hardness and increase the resistance to chemical erosion.

The scientists solved the problem by using an unused storage technique. They use gas to push chemical components into the air where they are synthesized to form glass. The obtained glass is colorless, transparent and very hard, with 50% of the composition being made from aluminum oxide.
