Industrial use of sapphire is military vehicles as transparent armor materials, but these materials if become cheap enough, will be able to replace the glass, become the material manufacture mobile phone screen. If the mobile phone accidentally landing also can not be broken, even if it is dropped on the concrete pavement is not broken.Industrial use of sapphire is likely than Corelle does not produce "gorilla glass" cheaper, "gorilla glass" is iPhone and other high-end intelligent mobile phone display manufacturing materials. A "gorilla glass" display prices for less than $3, and sapphire screen is likely to be approximately $30. Due to the improvement of competition and technology, sapphire display price may be in two years to below $20. The performance is better than that of glass, sapphire, so the price is competitive enough. In addition to diamond, sapphire is stronger than any other natural material hardness. It is "gorilla glass" hard three times, about three times the scratch resistance and resistance. Apple currently use sapphire protection iPhone 5 camera.
The major mobile phone manufacturers are considering the use of sapphire glass replaced. "I believe, some manufacturers will begin to test the water, release the intelligent mobile phone screen in 2013 the use of sapphire." Compared with the pure sapphire, another option is for laminating with transparent material, other low price and ultra-thin sapphire layer. This method can retain most of the performance advantages of sapphire, and at the same time, price and the glass is not far away.
The United States of America photovoltaic equipment suppliers are developing a much thinner than a human hair sapphire layer thin, than a millimeter thin glass mobile phone currently used much thinner. At the same time, the company also is to reduce the production cost of sapphire. Sapphire display price may only amount to a "gorilla glass" display three to four times, the future will further reduce.
