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. How does "transparency" work? by Gilmoure · · Score: 0, Flamebait

    What allows some things to pass light waves through them others to reflect light waves. I understand how reflection and color works. Photons hit the atoms of a substance and the substance obsorbs photons of some wavelengths while other bounce back. The wavelengths of the photons bouncing back are the color that we see. I just don't see how photons can pass all the way through some fairly dense substances. Any one, any one? Buhler?

    There was a comment posted awhile ago on another article that stated that the original name of the element was 'Aluminum', but in England they felt it should follow most of the other elements and end in ium, so they changed it to allow a 2nd spelling, 'Aluminium'.

    So, that would make those of us in the US at least spelling it the original way =]
