High hardness of Wearable Sapphire Window Device

Sapphire substrates belong to one of the most significant aspects of the construc-tional application of this material. They are used for epitaxy of semiconductor films such as Si, GaN, AlGaN, and for making integrated circuits. Sapphire substrates are inert, work at high temperatures and mechanical loads, and can be...

Stones for devices made of sapphire and ruby are most reliable. Sapphire pivots produced commercially in large quantities serve as supports for the shafts of those mechanisms that must work continuously for tens of years (e.g., water and gas meters). Such pivots are either flat or supplied with conical craters of...

High hardness of Sapphire Window As Phone Cover

Sapphire energy withdrawal windows can be used. One of the factors that limit the withdrawal of energy from devices is secondary electron resonance discharge in vacuum proportional to the secondary electron emission coefficient. As seen, sapphire compares favorably with other dielectrics in this characteristic....

High hardness of Sapphire Window As Fingerprint Recognition

In contrast to ZnSe windows, those made of sapphire may have a thickness around 5 mm with a complete absence of optical scattering. As shown by recent investiga-tions, large area (500 × 500 mm and 1,000 × 1,000 mm) is necessary for making transparent armor used for the windows of helicopters, special-purpose vehicles....
