Wear resistance of Sapphire Window As Phone Cover

Product Description

X-ray interferometers of the Fabry-Perot type at first contained silicon crystals as X-ray grids. Then a need arose for crystals possessing higher stability in a wide range of temperatures and pressures, so for this purpose sapphire was chosen. It should be expected that the creation of such interferometers will lead to the appear-ance of a new generation of optical X-ray devices such as filters, X-ray clocks, and most significantly a new method of the measurement of atomic scales (i.e., high-precision length standards) .

The next step in this direction may be bound to the development of devices on the basis of synchrotron radiation. For this class of high-precision apparatus, grids (mirrors) made of dislocation-free sapphire are required.

Sapphire could be used as windows: 1.mobile phone screens; 2. lens; 3. fingerprint recognition; 4. Wearable equipment windows and so on, because of  its unique advantages including: high sensitivity, scratch resistance, abrasion resistance, high temperature resistance, high pressure resistance, good chemical stability, and corrosion and deliquescence resistance.
