Recently, scientists in Japan revealed that they had created a new form of super-strong glass based on aluminum oxide. Test results indicate that the hardness of this new oxide glass has exceeded cast iron and copper. It’s even stronger than stainless steel. It may be used to make cellphone screens, allowing cellphone to be thinner and lighter. In addition, automobile windshield, building windows and many more applications could be benefited.
As Project leader, Professor Atsunobu Masuno of the University of Tokyo said, "We are looking for ways to mass produce this new material. We believe the technology is expected to be commercialized in 5 years.”Scientists combined alumina oxide with another metal oxide - tantalum oxide in a process known as “aerodynamic levitation” technique.The new material had also undergone Vickers hardness test (by pressing the pyramidal diamond indenter into the material). The test result indicated that the new material could resist a pressure of 9.1GPa, while in comparison, the HVs are 0.7-1GPa for stainless steel and 3.9GPa for high-carbon steel.
