Exploring the Immense Toughness of Transparent Aluminum

Video description

Transparent aluminum is a ceramic composed of aluminum, oxygen, and nitrogen. Transparent aluminum was once pure science fiction, a technical term used in a Star Trek movie from the 80s. Transparent aluminum or aluminum oxynitride, also known as ALON, is much stronger than standard glass, and over time, will become cheaper to make. But until then, it most likely will be used in applications spearheaded by NASA and the military. Courtesy of Interesting Engineering.
