Sapphire windows for mobile phones
Flat, spherical and cylindrical sapphire windows for mobile phones
Thanks to its strength properties sapphire is often used in those products where strong mechanical effect is present, such as dust particle scratching. It may seem strange at first sight, but glasses of common mobile phones undergo that kind of effects. That’s why in certain models mobile phone producers use sapphire as a material for these glasses. Generally such glasses have flat surface and right-angled shape.
