How is this possible? According to the studies, alumina (Al2O3) has special properties that, when combined with silicon dioxide, can cause the glass to gain even more hardness. This idea of using aluminum oxide (alumina) actually is not new, but the technique developed by the Japanese is the big difference.
Certain chemical component pushed into the air from where thy synthesized into the for of glass, almost 50 percent of the glass contain alumina, glass become very tough, colorless, just like steel solid material.
The method of construction here avoid the use of high temperatures (the process is performed at 1050 ° C for 12 hours) and a base to create the glass. The solution (above) is unusual, and consists in mixing the components directly in the air in an aerodynamic levitation furnace, which runs through the application of a gaseous oxygen solution.
So the Tokyo group prepared up a system for making glass that required no compartment by any means: they utilized gas to push the synthetic parts into the air, where they combined together. The outcome? A straightforward ultra glass that is half alumina and adversaries the Young’s modulus of steel and iron, which measures inflexibility and flexibility in solids.
