没想到人造兰宝石这么不值钱，以后要用它来做手机屏幕了 - 平均$30/个 色大胆小2013-03-21 20:25:33
(CNN) -- The next wave of smartphones and tablets might have super-sturdy screens fashioned from the human-made version of a gemstone.
Manufactured sapphire, a substance already used to armor some military vehicles, would be an almost unbreakable alternative to the glass now used on the displays of mobile devices,
Sapphire is the second-hardest material on the planet, behind only diamond. According to the MIT report, a sapphire smartphone screen wouldn't break when you dropped it and couldn't be scratched with a car key or by a sidewalk.
"I'm convinced that some (manufacturers) will start testing the water and release some high-end smartphones using sapphire in 2013," Eric Virey, an analyst for the market research firm Yole Développement, said in the report.
Currently, Apple uses manufactured sapphire to protect the camera lens on its iPhone 5.
Manufactured sapphire is made by melting down aluminum oxide, the compound that crystallizes into sapphire in nature, allowing it to cool and then cutting it with a diamond-coated wire saw.
