Glass is still used in the new process, being sandwhiched between an outer layer of the polished aluminum oxynitride and a polymer backing. .50-caliber test In a test this summer, the product held ...

While typical bulletproof glass requires up to three inches of material to halt a .50 caliber armor-piercing bullet, aluminum armor can stop it in half that.

Oxynitride Glass: A type of glass in which nitrogen is incorporated into the network structure, replacing a portion of oxygen. This modification results in enhanced mechanical, thermal and optical ...

The scientists at Surmet, a company that develops new high-tech materials, have created a special variant of alumina called ALON, or aluminum oxynitride.

The material, aluminium oxynitride, known as AION, is four times harder than fused silica glass, 85 per cent as hard as sapphire and stable up to a temperature of 1,200C.

Another recent development, originally reported by Amongtech, is that the Microsoft smartwatch could ditch the traditional glass covering in favor of aluminum oxynitride – “aluminium that is a ...

The chemical responsible for the material’s toughness is aluminium oxynitride, or ALON, a ceramic with similar optical and structural properties to sapphire.
