Beijing time, January 31st news, a magical super material appeared in the science fiction movie "Starship Trek IV: Rescue the Future" has now become a reality, a transparent aluminum material invented by scientists seems to be in line with this fantasy The materials in are very similar.

Although the scientists did not disclose the technical details of the development of transparent metal aluminum, but the super-transparent materials they developed have been verified to have better bulletproof effects. This material is called AION, which is a kind of aluminum oxynitride material, which is 4 times stronger than fused silica, 85% of sapphire, and can withstand a high temperature of 1200 degrees Celsius. At a thickness of 1.6 inches, this material can resist the impact of .50 caliber bullets, which can easily penetrate twice the thickness of ordinary safety glass.

When the thickness of the super-transparent aluminum reaches 1.6 inches, this material can resist the impact of .50 caliber bullets

In the science fiction movie "Starship Trek IV: Rescue the Future", engineer Scuti once invented a transparent aluminum. In fact, human research on transparent aluminum began at least in 1981, so the writer of this 1986 film made the idea of ​​transparent aluminum public earlier. At least the transparent aluminum in the film has some similarities with AION.

The resulting material is quite expensive, so it is usually only suitable for high-performance applications, especially in the military field

Today, this material can be mass-produced. The general method is to pour the aluminum oxynitride powder into a rubber mold to form the required rough model. Under the action of hydraulic pressure, the model is compressed to 15000psi until the powder becomes a green granule. Then, this granular structure was heated to 2000 degrees Celsius and lasted for several days. Although the melted material is opaque, it can appear optically transparent after mechanical polishing.

The resulting material is quite expensive, so it is usually only suitable for high-performance applications, especially in the military field. The ALON brand materials produced by Sumter, Massachusetts, USA are mainly used for armored vehicle bulletproof windows, lenses for battlefield optical equipment, telescope domes, and transparent round windows covering the top of missile sensors.
