Summary

Edge Defined Film-fed Growth (EFG®) sapphire crystals are being grown commercially as large, thick sheets that measure greater than 305 mm wide, 775 mm long, and 11 mm thick. The high strength, high hardness, and good transparency in the visible and infrared spectra make sapphire an ideal choice for transparent armor applications. This paper will discuss the properties of large sapphire sheets and the results from ballistic testing of selected sapphire transparent armor panels.
