Paper Abstract

Aluminum Oxynitride (ALON® Transparent Ceramic) combines broadband transparency with excellent mechanical properties. ALON’s cubic structure means that it is transparent in its polycrystalline form, allowing it to be manufactured by conventional powder processing techniques. Surmet’s has been producing and delivering ALON® windows as large as 4.4 sq. Ft. for both Armor and Sensor window applications. We have also recently scaled up our ALON® process to produce windows as large as 8 sq. Ft. for sensor window applications. Initial prototype windows of this size have been produced. These windows exhibit the same excellent levels of transmission, haze and clarity as seen in smaller ALON® windows that we have produced.
