    Aluminium oxynitride
    Aluminium oxynitride or AlON is a transparent polycrystalline ceramic with cubic spinel crystal structure composed of aluminium, oxygen and nitrogen. It is currently marketed under the name ALON by Surmet Corporation.[3] ALON is optically transparent (≥80%) in the near-ultraviolet, visible and near-infrared regions of the electromagnetic spectrum. It is 4 times harder than fused silica glass, 85% as hard as sapphire and nearly 15% harder than magnesium aluminate spinel. It can be fabricated to transparent windows, plates, domes, rods, tubes and other forms using conventional ceramic powder processing techniques. Because of its relatively low weight, optical and mechanical properties, and its resistance to damage due to oxidation or radiation, it shows promise for use as infrared, high-temperature and bulletproof and blast-resistant windows. Manufacturing methods continue to be refined. The cost is similar to that of synthetic sapphire.[citation needed]
