Transparent aluminum is an optically transparent aluminum that is a crystalline substance obtained from aluminate powder alloys. It is also known as aluminum oxynitride (AION) and ceramic alloy. In addition, transparent aluminum is polycrystalline ceramic with a cubic spinel crystal structure. It possesses mechanical strength due to which it is mostly the preferred metal in defense and security industry. Transparent aluminum finds a wide range of end use industries in infrared optical windows, sensor components, and the military defense industry.
