Now a collaboration of researchers from Caltech and the Department of Energy&#8217;s Lawrence Berkeley National Laboratory has created a form of glass that has both qualities. It&#8217;s stronger and tougher than steel or, indeed, any other known material. The material features palladium, a metal whose possible use in glasses was recognized 45 years ago.<\/p>\n<p>[. . .]<\/p>\n<p>The work is outlined in a study published this week in the journal <em>Nature Materials<\/em>. Marios Demetriou, a professor at Caltech and lead author of the paper, says the work involved finding a particularly strong version of the simplest form of glass, called marginal glass, and then turning it into the even stronger form known as bulk glass.<\/p>\n<p>&#8220;What we did here is find a very, very tough marginal glass made of palladium with small fractions of metalloids like phosphorus, silicon, and germanium, which yielded one-millimeter-thick samples. And we just said, let&#8217;s add very little of something that will make it bulk without making it brittle,&#8221; says Demetriou. By adding 3.5 percent silver to this marginal glass, Demetriou was able to increase the thickness to six millimeters while maintaining its toughness.<\/p>\n<\/blockquote>\n<p>H\/T to <a href=\"http:\/\/twitter.com\/vpostrel\/statuses\/24763402786177024\" target=\"_blank\">Virginia Postrel<\/a> for the link.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Arnie Bruce-Cooper reports on a recent development in high-strength glass: In the world of materials, strength (the amount of force a substance can withstand) and toughness (its capacity to resist fracturing) are not merely different attributes; they&#8217;re very difficult to achieve together.
