What I'm curious to know is, is it shatter or crack-proof? I don't know anyone who has "scratched" their phone screen but I see people all the time with shattered screens (or backs of phones) because they dropped their phone. To me it would be revolutionary if you could drop your phone without it cracking. "Cases" would be a thing of the past (and rightfully so).
- hereonbusiness 14y agoPlastic doesn't shatter.
- gph 14y agoPretty much any solid can shatter if enough force is applied. Case in point: Take a frisbee, lay it on the ground, and smash it with a sledgehammer. It will break or burst suddenly into pieces, i.e. shatter[1] [1]http://www.wordnik.com/words/shatter http://www.wordnik.com/words/shatter

- seanalltogether 14y agoSo I imagine that most people when they shatter the glass on their phone its because of compression of the glass. I found this http://abrisatechnologies.com/docs/AT%20Specialty%20Glass%20Technical%20Capabilities%20Brochure.pdf http://abrisatechnologies.com/docs/AT%20Specialty%20Glass%20... that says gorilla glass has a compressive strength of 800 MPa, and this http://www.roditi.com/SingleCrystal/Sapphire/Properties.html http://www.roditi.com/SingleCrystal/Sapphire/Properties.html says that sapphire has a compressive strength of 2.0 GPa. Additionally the flexural strength of sapphire appears to be ~20x higher then any of the "bending strengths" listed in that pdf
- acchow 14y agoI'm afraid of shattering from dropping the phone. Does that translate into a compression? Or something else? (vibration?) Honest question.
- reeses 14y agoFor common uses of "shatter" and "crack", yes, sapphire can. I've scratched the crap out of my 4s and 5 glass by forgetting "left pocket phone, right pocket keys" on too many occasions.
- eloisant 14y agoAre you talking about iPhones? They're not sapphires. Sapphires are commonly used in watches. Not the cheapest watches, but any watch more expensive than a few hundreds typically has a sapphire glass.
- reeses 14y agoThat's why I mentioned glass. The parent stated «I don't know anyone who has "scratched" their phone screen.» The parent also asked if sapphire could be shattered or cracked. My response to both comments is probably what confused you.
