Transparent Aluminium

Posted by Hemos on from the making-things-more-clear dept.

Lynx writes "As the german magazine Spiegel reports, scientists at the Fraunhofer Institute for Ceramic Technologies have developed a transparent tile made from aluminium oxide pellets baked at 1200C. The material is very hard, and could be used as bulletproof windows." Use the fish.

  1. Re:Windows out of Sapphire ? I WANT ONE! by mattr · · Score: 3, Interesting

    Just buy a space shuttle. They all come with them included.

    You can actually buy sapphire windows at least up to 15cm square some places I found on the net.. supermarket scanners also sometimes have sapphire windows apparently.

    The watchglass of my Rolex is a sapphire crystal. Looks cool, doesn't scratch. This page has info about synthetic sapphire watchglasses. It says Seiko coats mineral glass with synthetic sapphire (sapphlex they call it) to make it hard.
