TOKYO, Nov. 3 (UPI) -- Shattered smartphone screens may soon be a thing of the past. Scientists in Japan say they've created a new type of glass stronger than most metals and nearly as tough as steel.
The glass is made by infusing silicon dioxide with alumina, an aluminum oxide. Traditional glass-making technologies complicate the introduction of alumina during the formation process, as the silicon dioxide crystallizes when it makes surface contact with a solid, like the alumina container.
