“Gorilla Glass” critica uso da Safira


Tony Tripeny, VP da Corning Glass que fabrica o Gorilla Glass, criticou o uso da Safira. 10x mais caro. 1.6x mais pesado. Gasta 100x mais energia. Ainda que resista aos riscos, o Gorilla é 2.5 resistente a pressão que a Safira.


When we look at it, we see a lot of disadvantages of Sapphire versus Gorilla Glass. It’s about 10 times more expensive. It’s about 1.6 times heavier. It’s environmentally unfriendly. It takes about 100 times more energy to generate a Sapphire crystal than it does glass. It transmits less light which it means either dimmer devices or shorter battery life. It continues to break. I think while it’s scratch resistant product it still breaks and our testing says that Gorilla Glass, about 2.5 times more pressure that it can take than Sapphire on. So when we look at it, we think from an overall industry and trend that is not attractive in consumer electronics. (traduzir)

The formation takes about 4,000 times longer than Gorilla Glass at a significantly higher melting temperature. Its hardness makes machining more difficult and costly. Then the cost per unit increases exponentially because when you have defects in boundaries in the crystal growth process, you essentially cut them out and so unlike glass where we have developed technologies so that we can have very large pristine pieces of glass, when you have that on crystals, what you end up doing is always having a yield issue. So it is really those items that make things more expensive. (traduzir)
