High Performance, Nanosized Grain AlON for Optical Applications

Abstract
This invention produces a high performance transparent polycrystalline aluminum oxynitride (AlON). The demand for a high-hardness, high-strength transparent material is steadily growing for optical, defense, and energy applications. This is a high-quality, low-cost substitute for sapphire and aluminum oxide materials.
