Using diamonds to cut glass is not something new, however, recently a research team in northern China has built a hardest glass material in the world, which can be easily removed Deep scratches on diamond surfaces. A 1mm-wide AM-III glass piece scratches the surface of a natural diamond.

Meanwhile, a natural diamond usually has a hardness of 50 to 70 GPA, even some of the hardest artificialists can only reach 100 GPA.AM-III to take a lot of time to produce Series and costs of this type of material are not cheap
. However, this glass material can be used as a bulletproof glass with a higher hardness of 20 to 100 times higher than today's current products today. The researchers said water materials Tinh looks unattractive as jewelry, but it can be widely used in the high-tech industry. For example, AM-III is an almost semiconductor almost silicon
The ability to transmit current at will also make it a bright candidate for use in photovoltaic devices, including weapons, operating in harsh environments such as high pressure and temperature. Professor Tian Yongjun and colleagues of the High Pressure Science Center of Yen Son University, in Qin Hoang Island City, Hebei Province, said in National Science Review on August 5: "Type of material This super hard semiconductor carbon is super hard, this super durable is the excellent candidate for the most demanding practical apps ".kim outline is a colorless crystal consisting of pure carbon with very high hardness. Photo: AFPTY course, the fabrication of this ultra-durable glass material is more complicated than crystals. The production process of AM-III needs fullerene, molecules composed of carbon atoms, hollow structures like a very small soccer ball.Im-III can be produced with many shapes and sizes different. And unlike diamonds, with relatively weak surfaces because of the complex link of atoms, the AM-III surroundings are very hard. According to researchers, this attribute will increase the potential of the application of AM-III.Nam in 2013, Mr. Tian's team also created the world's hardest material visible with the naked eye , It is a boron nitride crystal with 200 GPA hardness, double diamond doubles
