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, and so forth Work in the creation of this kind of armor has been started in the United States, Russia, Ukraine, Czech Rep., and other countries.
The strength of a “glass sandwich” with a thickness of 25–35 mm will correspond to that of ~100-mm-thick armored glass. The upper layer of such a “glass sandwich” would contain a sapphire sheet meant to absorb the greater part of the kinetic energy of bullets. The rest of this energy will be absorbed in the layers of glass and plastic.
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.
