AM-III is a glass material made of carbon that is as hard as a diamond. It was developed by Chinese researchers for industrial purposes. It is a semiconductor that is capable of passing electric current. It is almost as efficient as silicon. The material had reportedly left deep scratches on a diamond.
The glass material can be used for developing bulletproof windows. It will be a major asset for the weapon industry, as it can be used as a photoelectric device and can withstand extreme temperature. This novel device has not yet entered into mass production.
